<h1><a name="description">DESCRIPTION</a></h1>
|
||
|
<p><em>tw_cli(8)</em> is a Command Line Interface Storage Management Software for
|
||
|
3ware ATA RAID Controller(s). It provides controller, logical unit and drive
|
||
|
management. tw_cli can be used in both interactive and batch mode, providing
|
||
|
higher-level API (Application Programming Interface) functionalities.</p>
|
||
|
<p>The CLI prompt indicates the current object in focus, expressed in URI (Universal
|
||
|
Resource Identifier) syntax consisting of a hostname (<em>//hostname</em>), and an object
|
||
|
path (<em>/path/path/object</em>) such as <em>//elvis/c0/u0</em>. User can set the focus to a
|
||
|
particular object by <em>focus URI</em>.</p>
|
||
|
<p>CLI also supports <em>comments</em>. Command lines beginning with <em>#</em> denotes start
|
||
|
of comment. This feature is mostly useful with batch processing via <em>-f script</em>
|
||
|
flag.</p>
|
||
|
<p>CLI uses the following terminology:</p>
|
||
|
<p><strong>Logical Units.</strong> Usually shortened to ``units'', these are block devices presented
|
||
|
to the operating system. A logical unit can be a one-tier, two-tier, or three-tier
|
||
|
arrangement. Spare and Single logical units are examples of one-tier units.
|
||
|
RAID-1 and RAID-5 are examples of two-tier units and
|
||
|
as such will have sub-units. RAID-10 and RAID-50 are examples of three-tier units
|
||
|
and as such will have sub-sub-units.</p>
|
||
|
<p><strong>Port.</strong> 3ware controller models up to the 9650SE series have one or many ports
|
||
|
(typically 4, 8, 12, 16, or 24). Each port can be attached to a single disk drive.
|
||
|
On a controller such as the 9650SE with a multilane serial port connector, one
|
||
|
connector supports four ports. On the 9690SA and 9750 controllers, connections
|
||
|
are made with phys and vports (virtual ports).</p>
|
||
|
<p><strong>Phy.</strong> Phys are tranceivers that transmit and receive the serial data stream
|
||
|
that flows between the controller and the drives. The 9690SA controller
|
||
|
have 8 phys. These ``controller phys'' are associated with virtual ports (vports)
|
||
|
to establish up to 128 potential connections with the SAS or SATA drives. Each
|
||
|
controller phy can be connected to a single drive, or can be connected through
|
||
|
an expander to additional drives.</p>
|
||
|
<p><strong>VPort.</strong> Connections from the 9690SA and 9750 controllers to drives are referred
|
||
|
to as <em>virtual ports</em>, or vports. A vport indicates the ID of a drive, whether
|
||
|
it is directly connected to the controller, or cascaded through one of more
|
||
|
expanders. The vport, in essense, is a handle in the software to uniquely
|
||
|
identify a drive. The port ID or vport ID allows a drive to be consistently
|
||
|
identified, used and managed in a RAID unit. For dual-ported drives, although
|
||
|
there are two connections to a drive, the drive is still identified with one
|
||
|
vport handle. <strong>Note:</strong> With the controller summay via the command ``show'',
|
||
|
the number of (V)Ports shown may contain two times (2X) the number of drives
|
||
|
(suggesting the dual-ported drive type) even though the (V)Port column of
|
||
|
the summary to the command ``/cx show'' contains only the number of vports
|
||
|
corresponding to the number of drives. This is because the drive is
|
||
|
identified with only one vport handle.</p>
|
||
|
<p><strong>NOTE:</strong> For all practical purposes, hereafter port and vport are used
|
||
|
interchangeably in reference to a drive (or disk). Therefore, unless otherwise
|
||
|
specified, the mention of port implies vport as well. That is, while ``port''
|
||
|
is mentioned to denote a drive, it is implied that for the applicable controller
|
||
|
series, the reference also applies to vport.</p>
|
||
|
<p>CLI supports a set of primary command syntax and a set of legacy command syntax
|
||
|
that is the old or original command syntax. <strong>Note:</strong> The primary command syntax
|
||
|
replaces that legacy command syntax and as such support for legacy commands will
|
||
|
discontinue in the near future.</p>
|
||
|
<p>Please also note that some of the commands listed in this document are qualified
|
||
|
with restrictions of controller type/model support. For example, ``9000 series'' or
|
||
|
``9550SX and higher'' may be next to a command. The following is a summary of the
|
||
|
controller qualified specifications.</p>
|
||
|
<p>Commands with:</p>
|
||
|
<pre>
|
||
|
No specifications Could be used across all controller platforms. This includes
|
||
|
the 7000 and 8000 series controllers.
|
||
|
9000 series Could be used in all controllers in the 9000 series. This
|
||
|
excludes the 7000 and 8000 series controllers, and includes
|
||
|
the 9550SX, 9590SE, 9650SE, 9690SA and 9750 controllers.
|
||
|
9550SX and higher For controller models 9550SX, 9650SE, 9690SA and 9750.
|
||
|
9650SE and higher For controller models 9650SE, 9690SA and 9750.</pre>
|
||
|
<p>For the Mac system, while still true, the command qualifier is not meaningful
|
||
|
as all commmands are supported, provided the controller model is 9590SE or 9650SE
|
||
|
(or above).</p>
|
||
|
<p>Here is a summary of the controllers and their associated support:</p>
|
||

noted. Also, CCU (Chassis Control Unit) refers to the JMR enclosure/Sidecar.</p>
|
||
|
<p>This document organizes the CLI command set as different types of Object
|
||
|
Messages, and descriptions and examples are presented for each object message
|
||
|
or command. While some of the system features could be invoked with one
|
||
|
``set'' command and correspondingly displayed with a ``show'' command and as such,
|
||
|
information regarding the feature may be self-contained within the description
|
||
|
of the set command, other features may require or involve a set of commands
|
||
|
that work together and may not be so straight-forward. For these, the command
|
||
|
descriptions may present a fragmented view of the feature as a result. For
|
||
|
an encapsulated view of certain features and their relevant command set, please see
|
||
|
the <strong>Features</strong> section of this document.</p>
|
||
|
<p>This document, therefore, may be used as a reference for individual commands
|
||
|
and also as a reference for supported features. For the former please see
|
||
|
the <strong>Primary Command Syntax</strong> sections, and for the latter please see the
|
||
|
Features sections.</p>

<h1><a name="primary_command_syntax">Primary Command Syntax</a></h1>
|
||
|
<p>The primary command syntax will replace the legacy command syntax in the future
|
||
|
releases. The new and improved command format follows a general grammar in
|
||
|
the form:</p>
|
||
|
<pre>
|
||
|
Object Message Attributes</pre>
|
||
|
<p>Objects can be shell commands or can specify a controller, logical unit,
|
||
|
port or vport (drive), or battery backup unit (bbu). Messages are commands
|
||
|
sent to the requested objects. It may be a read operation such as for the
|
||
|
command ``show'', or a write operation for the set, delete, add, stop, start,
|
||
|
or remove commands. Attributes specify the values to read or write.
|
||
|
Attributes are either <em>Boolean Attributes</em> or <em>Named Attributes</em>. Value of a Boolean
|
||
|
attribute is deduced by presence. Value of named attributes are
|
||
|
expressed in a ``key = value'' format.</p>
|

<p>
|

</p>
|

<h2><a name="shell_object_messages">Shell Object Messages</a></h2>
|

<h2><a name="controller_object_messages">Controller Object Messages</a></h2>
|
||
|
<p>Controller Object Messages are commands (a.k.a. methods/messages) that are sent to
|
||
|
an instance of a controller such as <em>/c0</em>.</p>
|
||
|
<dl>
|
||
|
<dt><strong><a name="item__2fcx_show"><em>/cx</em> <strong>show</strong></a></strong><br />
|
||
|
</dt>
|
||
|
<dd>
|
||
|
This command shows summary information on the specified controller <em>/cx</em>. This
|
||
|
report consists of two to three parts: the <strong>Unit Summary</strong> that lists all units
|
||
|
present, the <strong>Port Summary</strong> that lists the ports and disks attached to them,
|
||
|
and if a BBU unit is installed, the <strong>BBU Summary</strong> that shows information on
|
||
|
the BBU.
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The <strong>Unit Summary</strong> section lists the units present with the unit number,
|
||
|
unit type (such RAID 5), and unit status (such as OK, VERIFYING, INITIALIZING,
|
||
|
etc.). The <strong>%RCompl</strong> reports the percent completion of the unit's Rebuild, if
|
||
|
this task is in progress. The <strong>%V/I/M</strong> reports the percent completion of the
|
||
|
unit's Verify, Initialize, or Migrate, if one of these are in progress. The
|
||
|
stripe size, the usable capacity in gigabytes, the cache setting, and the
|
||
|
autoverify setting are also listed.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p><strong>Note</strong>: If a ``*'' appears at the end of the status, there is an error on one of
|
||
|
the drives in the unit. Rescanning the controller will clear the error status
|
||
|
if the condition no longer exists.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>For controller models up to the 9550SX and 9650SE with Release 9.5.1 or
|
||
|
earlier, the <strong>Port Summary</strong> section lists all present ports and for each port,
|
||
|
the port number, drive status, unit affiliation, drive size (in blocks of 512
|
||
|
bytes), and the disk vendor assigned serial number are reported.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>For the 9750, 9690SA and 9650SE controller with Release 9.5.2 or later,
|
||
|
this section lists the ports or virtual ports present and for each port, the port
|
||
|
or virtual port (VPort) number, drive status, unit affiliation, drive type,
|
||
|
phy number (if direct attached), the enclosure and slot (if expander attached),
|
||
|
and model number of the drive are reported.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p><strong>Note</strong>: Unlike the 9550SX or older display, if a drive is not present, instead
|
||
|
of showing the port with the status NOT-PRESENT with dashes ('-') across the
|
||
|
columns in the summary table, for the 9750, 9690SA and 9650SE with Release 9.5.2
|
||
|
or later, that port entry is not listed. Thus, unlike the older display, the
|
||
|
port numbers in this list may not be sequential. Moreover, if there are no
|
||
|
drives present at all for the specified controller, the output of its Port
|
||
|
Summary would show an empty summary consisting of only the header.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The <strong>BBU Summary</strong> section lists the online state, readiness, and status of
|
||
|
the BBU unit, along with the voltage, temperature, charge capacity expressed
|
||
|
as time remaining in hours, and the BBU's last test date.</p>

<p><strong>group=3|4|5|6|7|8|9|10|11|12|13|14|15|16</strong> consists of the number of disks per group
|
||
|
for a Raid 50 type. <strong>Note:</strong> This attribute can only be used when type=raid50. Also,
|
||
|
group=13-16 is applicable to the 9690SA and 9750 controllers only.</p>

</dd>
|

|
<dd>
|
||
|
<p>Recall that a RAID-50 is a multi-tier array. At the most bottom layer,
|
||
|
N number of disks per group are used to form the RAID-5 layer. These
|
||
|
RAID-5 arrays are then integrated into a RAID-0. This attribute allows
|
||
|
you to specify the number of disks in the RAID-5 level. Valid values
|
||
|
are 3, 4, 5, 6, 7 and 8.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>Note that a sufficient number of disks are required for a given pattern or
|
||
|
disk group. For example, given 6 disks, specifying 3 will create two RAID-5.
|
||
|
However given 12 disks, specifying 3 will create four RAID-5 under the RAID-0
|
||
|
level. Given 6 disks and grouping of 6 is not allowed, as you'll basically
|
||
|
be creating a RAID-5.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The default group varies based on number of disks. For 6 & 9 disks, default
|
||
|
is group=3. For 8 disks, default is group=4. For 10 or 15 disks, default is
|
||
|
group=5. For 12 or 16 disks, default is group=4. For 14 disks, default is
|
||
|
group=7. Case of 12 disks could be grouped with group=3, group=4, or group=6.
|
||
|
Group=4 was set by default as it provides best net capacity and performance.
|
||
|
Case of 15 disks could be grouped with group=3 or group=5. And case
|
||
|
of 16 disks could be grouped with group=4 and group=8.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>Note that the supported group number indicated depends on the number of ports
|
||
|
on the controller. group=16 is the maximum and it is available on the 9690SA
|
||
|
and 9750 controllers only.</p>

<dd>
|

|
<p><strong>noscan</strong> attribute instructs CLI not to notify OS of creation of the new unit.
|
||
|
By default CLI will inform the OS. One application of this feature is to avoid
|
||
|
the OS from creating block special devices such as /dev/sdb and /dev/sdc as some
|
||
|
implementations might create naming fragmentation and creating a moving target.</p>

|

|
<dd>
|

|
<p><strong>nocache</strong> or <strong>nowrcache</strong> attribute instructs CLI to disable the write cache
|
||
|
on the newly created unit. Enabling the write cache increases performance at
|
||
|
the cost of high-availability. No caching is recommended when no BBU or UPS
|
||
|
is installed. The system default for the write cache is enable. If a BBU or
|
||
|
UPS is not installed, to avoid possibility of data loss in the event of sudden
|
||
|
power loss, it is recommended that nocache or nowrcache be specified.</p>

</dd>
|

|
<dd>
|

|
<p><strong>nordcache</strong> attribute instructs CLI to disable the read cache on the newly

created unit. Enabling the read cache increases performance. The <strong>rdcachebasic</strong>
|
||
|
attribute instructs CLI to set the read cache mode on the newly created unit
|
||
|
to <em>Basic</em>. Please note that it is not necessary to include any read cache
|
||
|
attribute if you wish to select the <em>Intelligent</em> mode of Read Cache, since
|
||
|
the system default is Read Cache Intelligent. See ``/cx/ux set rdcache'' for
|

more information.</p>

<p><strong>autoverify|noautoverify</strong> attribute enables or disables, respectively, the

autoverify attribute on the unit that is to be created. For more details on this
|
||
|
feature, refer to the <em>/cx/ux set autoverify</em> command section of this document.
|
||
|
This feature is not supported on controller models 7000/8000. For the 9650SE,
|
||
|
9690SA, and 9750 controllers that support Basic Verify, autoverify will be set
|
||
|
to ON by default for the new unit to be created. For other 9000 series controllers
|
||
|
that do not support Basic Verify, autoverify is set to OFF by default for the new
|
||
|
unit. The following table should help clarify regarding the defaults:</p>

<dd>
|
||
|
<p><strong>Note</strong>: while there is no reason to issue both <em>autoverify</em> and <em>noautoverify</em>
|
||
|
together at unit creation, CLI allows you to do so. Keep in mind however, that
|
||
|
in this case, only the last value specified would be used. That is, for
|
||
|
example, if you specified the command '/c0 add type=raid5 disk=0-2 autoverify
|
||
|
noautoverify', then you are essentially specifying that 'autoverify=OFF' for /c0.</p>

<dd>
|

<p><strong>noqpolicy</strong> attribute instructs CLI to disable the qpolicy (drive queuing) on the
|
||
|
newly created unit. The default qpolicy is <em>on</em> (i.e., noqpolicy is not specified).
|
||
|
For the spare unit, drive queueing is not meaningful and the qpolicy cannot
|
||
|
be set. During unit creation, specifying <em>noqpolicy</em> for spare returns an error.</p>

<p><strong>name=string</strong> attribute allows user to name the new unit. The maximum characters

<p>The attribute <strong>rapidrecovery</strong> specifies the Rapid RAID Recovery setting for
|

|
the unit to be created. Rapid RAID Recovery can speed up the rebuild
|
||
|
process, and it can speed up the initialize and verify tasks for redundant
|
||
|
arrays in the RAID system upon the event of an unclean system shutdown.
|
||
|
This feature allows for expedited boot-up time in the event of an unclean
|
||
|
shutdown. Setting this option to <em>all</em> applies the policy to the rebuild,
|
||
|
initialize and verify tasks at reboot. Setting it to <em>rebuild</em> applies the
|
||
|
policy to the rebuild tasks only. If the policy is set to <em>disable</em>, then
|
||
|
none of the tasks would be sped up.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p><strong>Note:</strong> Once this attribute is set, the policy setting is persistent in the

|
changed for that unit at a later time.</p>

This command instructs the controller to commit its dirty DCBs to
|
||
|
persistent storage (ie disks). While controller is processing I/O requests
|
||
|
against underlying disks, an in-transaction bit is set. If a failure (such
|
||
|
as power failure) is experienced, subsequent read from the disks, will inform
|
||
|
the controller that an un-clean shutdown took place. This command allows the
|
||
|
end user to complete all pending I/Os on disks and clear the in-transaction
|
||
|
bit.

<p>Typical application of this feature is when an application is using a given
|

|
unit in raw mode (such as databases) and user would like to shutdown the
|

|
host (Including UPS post failure automations). This command can then expedite
|
||
|
the process by instructing the controller to finish pending requests, clear
|
||
|
DCB's in-transaction flag as we are going down.</p>

Asynchronous events or AENs (Asynchronous Event Notifications) of the controller,
|
||
|
also known as 'controller alarms', are originated by firmware and captured by
|
||
|
their respective device drivers. These events are kept in a finite queue inside
|
||
|
the kernel, awaiting extraction by user space programs such as CLI and/or 3DM2.
|
||
|
These events reflect messages of varying severity levels. The levels range
|

in order of severity: INFO, WARNING, and ERROR, respectively.

message contains the severity as well, hence the ``Severity'' column shows a '-'

|
||

message the earlier it is in the table. The order of the messages could be

<p>For the 9650SE and newer RAID controllers, the Verify Task Schedule can be either
|
||
|
<strong>basic</strong> or <strong>advanced</strong> (For details about the two types and the associated
|
||
|
commands, please see the 'Features' section.) The basic Verify Task Schedule
|
||
|
sets a weekly day and time for verification to occur, and is designed to be
|
||
|
used with unit auto-verify. The advanced Verify Task Schedule provides
|
||
|
more control, and is equivalent to the Verify Task Schedule available for
|
||
|
9550SX and earlier RAID controllers.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>For the advanced Verify Task Schedule, up to 7 time periods can be registered,
|
||
|
known as timeslots (or simply slots) 1 through 7. This task schedule can be
|
||
|
managed by a set of commands including <em>add</em>, <em>del</em>, <em>show</em> and <em>set</em>. The task
|
||
|
schedule has a slot id, start-day-time, duration, and status attributes. Rebuild
|
||
|
follow similar background task schedules.</p>

<dd>
|

|
<p>Verify activity attempts to verify all units based on their unit type. Verifying
|
||
|
RAID-1 involves checking that both drives contain the exact data. On RAID-5 and
|
||
|
RAID-6, the parity information is used to verify data integrity. RAID-10 and 50
|
||
|
are composite types and follow their respective array types. On the 9000 series,
|
||
|
non-redundant units such as RAID-0, JBOD, single, and spare, are also verified
|
||
|
(by reading and reporting un-readable sectors).</p>

|
<em>add</em>, <em>del</em>, <em>show</em> and <em>set</em> a task. Background tasks have attributes of

slot id, start-day-time, duration, and status.

This command allows you to set a controller based disk spin up policy. The value
|
||
|
must be a positive integer between 1 and the number of disks/ports supported on
|
||
|
the controller (e.g. 4, 8, 12, 16). This policy is used to stagger spin ups of disks
|
||
|
at boot time in order to spread the power consumption on the power supply.
|
||
|
For example, given a spin up policy of 2, the controller will spin up two disks
|
||
|
at a time, pause, and then spin up another 2 disks, and so on. The amount of time
|
||
|
to pause can be specified with the spin up stagger time policy.

This command is associated with the stagger spin-up feature during hot-plug.
|
||
|
With stagger spin-up enabled (see command <strong>/cx set spinup</strong> and <strong>/cx set stagger</strong>),
|
||
|
during reset or power on, the controller will try to detect all drives that are
|
||
|
present and spin them up staggered in time, allowing the spread of power consumption
|
||
|
on the power supply. Upon drive hot-plug, that is, <strong>not</strong> on power-on or reset, the
|
||
|
default behavior of the system is automatic detection of the drives and immediate
|
||
|
spin-up. This command would change the default behavior and set the controller
|
||
|
to spin-up as the system at power-on.
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The <strong>autodetect=on|off</strong> attribute configures the controller drive auto-detect
|
||
|
setting. It should be set to <em>off</em> to initiate the sequence for the stagger
|
||
|
spin-up during hot-plug process. After the drives are inserted or re-inserted to
|
||
|
the ports (as specified in the second attribute decribed below), it should be set
|
||
|
back to <em>on</em> to complete the configuration process for the controller to initiate
|
||
|
the drive spin-up.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The <strong>disk=</strong><strong><p:-p</strong>><strong>|all</strong> attribute specifies one or many disks (i.e., drives
|
||
|
or ports). If a port is empty (i.e., no drive inserted), the echo message of the
|
||
|
command refers to a port, and if there is already a drive inserted the message
|
||
|
refers to a disk. The example below shows that auto detect has been set to <em>off</em>
|
||
|
to initiate stagger spin-up during hot-plug, where <em>port 3</em> was empty and
|
||
|
<em>ports 5</em> and <em>6</em> had drives inserted.</p>

</dd>
|

|
<dd>
|
||
|
<pre>
|
||
|
1. Issue command (set autodetect=off) to disable automatic detection of the
|
||
|
ports for staggered spin-up.
|
||
|
2. Pull out the drives of the specified ports (if not empty).
|
||
|
3. Replace the drives previously removed at the ports specified.
|
||
|
4. Issue command (set autodetect=on) to enable auto detect of the ports with
|
||
|
the newly inserted drives.</pre>
|
||

</dd>
|
||
|
<dd>

<p><strong>Read Cache Basic</strong> is used to store data locally on the controller that

<p><strong>Read Cache Intelligent</strong> enables the Intelligent Read Prefetch (IRP) feature.
|
||
|
This new feature includes a typical read ahead caching method, which is used
|
||
|
to proactively retrieve data from media and store it locally on the controller
|
||
|
with the anticipation that it may be requested by the host. For example, the
|
||
|
host may read blocks 1, 2, and 3. With read-ahead caching, the controller will
|
||
|
also retrieve and hold in its cache blocks 4, 5, and 6 in anticipation of
|
||
|
getting those command requests from the host. By loading a larger set of data
|
||
|
into the cache, chances are improved that another request can be filled by data
|
||
|
that is already in the cache. This can be helpful with applications that are
|
||
|
sequential in nature, such as video on demand, video surveillance playback,
|
||
|
and restoring from a disk-to-disk backup. Performance benefits of read-ahead
|
||
|
are especially pronounced when the host queue depth is low. In addition,
|
||
|
read-ahead cache also improves sequential read performance when the unit is
|
||
|
degraded. The Intelligent Read Prefetch (IRP) feature also includes some
|
||
|
intelligent and adaptive stream management layer to improve performance at
|
||
|
higher queue depth in multiple read only or mixed read/write stream
|
||
|
environments. The performance improvements should be seen for most type of
|
||
|
arrays and in any modes.</p>

<p>This command allows you to migrate an existing unit (aka source) to a unit with
|
||
|
<em>type=RaidType</em> (aka destination), to increase capacity, change the RAID level (with
|
||
|
the same or increased capacity), or change the stripe size.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The unit that results from the migration (destination unit) is subject to similar
|
||
|
rules and policies that apply when creating a new unit. For example, a valid number
|
||
|
of disks and parameters must be specified. The destination unit must use all source
|
||
|
disks and potentially augment the number of disks in the <strong>disk=<em>p:-p</em></strong> disk list.
|
||
|
Unspecified parameters are assigned default values (stripe size of 64K, write
|
||
|
cache enabled, autoverify disabled, and ignoreECC disabled).</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>The unit to be migrated (source unit) must be in a normal state (not degraded,
|
||
|
initializing, or rebuilding) before the migration. If the source unit is of type
|
||
|
RAID-1 and the destination unit is of type single, the disk-specifier of the
|
||
|
migration command [disk=<em>p:-p</em>] is actually not optional and must <strong>not</strong> be included
|
||
|
in the command. The drives in the RAID-1 array would become multiple units of type
|
||
|
single after the migration, and the source drives are the destination drives.
|
||
|
Specifying more drives with the ``disk='' option would return an error.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>Both source unit name and serial number will be carried over to the destination
|
||
|
unit. However, the RAID-1 to single migration path is a special case. In this case,
|
||
|
the <strong>migrate</strong> command splits both drives into two identical single disks. The
|
||
|
source unit name will be duplicated on the destination units, or single disks,
|
||
|
but the source unit serial number will <strong>not</strong> be carried over to new unit. The

new destination unit will have its own serial number.</p>

adding another drive, due to the need for additional storage capacity for parity bits.</p>

<p><strong>disk=p:-p</strong> consists of a list of ports or vports (disks) to be used in addition

index separators. A dash indicates a range and can be mixed with ``:''. For example

array. At the most bottom layer, N number of disks per group are used to form the
|
||
|
RAID-5 layer. These RAID-5 arrays are then integrated into a RAID-0. This option
|
||
|
allows you to specify the number of disks in the RAID-5 level. Valid values are 3,

4, 5 and 6. For example <strong>group=3</strong> indicates 3 disks of RAID-5 at the bottom layer

<dd>
|

<p>Note that a sufficient number of disks are required for a given pattern or disk

given 12 disks, specifying 3 will create four RAID-5 under the RAID-0 level. Given

6 disks and grouping of 6 is not allowed, as you'll basically be creating a RAID-5.</p>

<p>The default disk <strong>group</strong> varies based on number of disks. For 6 & 9 disks, default

group=5. For 12 or 16 disks, default is group=4. For 14 disks, default is

group=7. Case of 12 disks could be grouped with group=3, group=4, or group=6.

Group=4 was set by default as it provides best net capacity and performance.

Case of 15 disks could be grouped with group=3 or group=5. And case

<p><strong>noscan</strong> instructs CLI not to notify the operating system (OS) about the

creation of the new unit. By default CLI will inform the OS. One application
|
||
|
of this feature is to prevent the OS from creating block special devices such

as /dev/sdb and /dev/sdc as some implementations might create naming fragmentation

<p><strong>nocache</strong> instructs CLI to disable the write cache on the migrated

unit. Enabling write cache increases performance, but at the cost of potential
|
||
|
data loss in the event of sudden power loss (unless a BBU or UPS is installed).
|
||
|
By default the cache is enabled. Unless there is a BBU or UPS installed, to
|

avoid the possibility of data loss in the event of sudden power loss, it is

recommended that <strong>nocache</strong> be specified.</p>

<p><strong><em>Migration Process.</em></strong> In all cases of migration, the background migration process
|
||
|
must be completed before the newly sized unit is available for use. You can continue
|
||
|
using the original unit during this time. Once the migration is finished, a reboot
|
||
|
will be required if you are booted from the unit. For secondary storage, depending
|
||
|
on your operating system, you may need to first unmount the unit, then use CLI to
|
||
|
'remove' and 'rescan' the unit so that the operating system can see the new capacity,
|
||
|
and then remount the unit.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>You may also need to resize the file system or add a new partition. For instructions,
|
||
|
consult the documentation for your operating system.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p><strong>Note</strong>: It is important that you allow migration to complete before adding drives
|
||
|
to the unit or move it to another controller. Making any physical changes to the
|
||
|
unit during migration may cause the migration to stop, and can jeopardize the safety
|

|
of your data.</p>

<p>Please note that the migration path of raidtype Single to RAID-1 is a special
|
||
|
case. Since the single unit would become a mirrored array, technically this
|
||
|
is not a migration. As a result this command shows a different status than
|
||
|
other migration paths. In addition, the status of the newly specified disk
|
||
|
would show DEGRADED until the ``migration'' is complete.</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p>For example, below is a system with two migrating units, /c0/u0 and /c0/u1.
|
||
|
u0 is migrating from a RAID-10 to a RAID-0 array, while u1 is migrating from
|
||
|
Single to a RAID-1, initiated by the following commands:</p>
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<pre>

/c0/u0 migrate type=raid0</pre>

This command allows you to remove (or export) a port <strong>/cx/px</strong> (or drive).
|
||
|
Exporting a port will instruct the firmware to remove the specified port
|
||
|
from its pool of managed ports, but retains the DCB (Disk Configuration Block)
|
||
|
meta-data on the attached disk. You can import (or re-introduce) the port
|
||
|
via the <strong>rescan</strong> command. Use <em>noscan</em> to bypass informing the OS of this
|
||
|
change. Default is to inform the OS. The quiet option is for the non-interactive
|
||
|
mode.

This command is for the 9650SE with Release 9.5.2 or later, and 9690SA
|
||
|
and newer controllers only. This command presents a summary report on the
|
||
|
specified phy. The 'Device Type' column indicates whether the connected
|
||
|
device is an enclosure, or a drive of type SATA or SAS. The 'Device' column
|
||
|
is the device ID or handle. There are three 'Link Speed' columns: 'Supported'
|
||
|
denotes the link speed capability of the phy/device, 'Enable' denotes the
|
||
|
current link speed setting, and 'Control' denotes the link control setting.
|
||

|
<p>Enclosure Object Messages are commands (a.k.a. methods/messages) that are sent to an

|
instance of an enclosure such as e0. The enclosure element object messages are
|
||
|
commands sent to an instance of the enclosure element such as fan0. The subsections

which follow describe the commands of the enclosure and the enclosure elements. The
|

latter includes commands for the slot, fan, temperature sensor, and power supply
|

elements.</p>
|

|
<p>The command descriptions and examples of this section are shown with the syntax

This command controls the audibility and state of the enclosure alarm. It provides
|
||
|
the ability to silence the alarm after it has been turned on. It also gives you
|
||
|
the option to mute or unmute the alarm setting. In the case where a known
|
||
|
condition would set off the alarm and you do not wish to hear the sound of the
|
||
|
alarm, this command could be used to mute the potential audible alarm.
|
||
|
</dd>
|
||
|
<dd>
|
||
|
<p><strong>Note:</strong> Some enclosures support alarms but not the mute/unmute function. For
|
||
|
these enclosures, the command to set the alarm to <em>mute</em> will return an error
|
||
|
message indicating that the feature is not supported. In this case, the alarm
|
||
|
setting of <em>unmute</em> would seem to be supported. This is because the <em>unmute</em>
|
||
|
setting is the default and as such there is no error response. In effect, for
|
||
|
these enclosures, the alarm is not mutable and would stay unmute
|
||
|
.
|
||
|
Example:</p>
|
||
|
</dd>

<p><strong>Note:</strong> You <em>cannot</em> turn ON the alarm. The alarm is turned on by firmware when

it detects a degraded state pertaining to a drive or array. Setting the alarm

to ON will return an error.</p>

<p><strong>Note:</strong> Help stops at this /Object/Command level. Help does not extend to the
|
||
|
Attribute level, and thus inquiry for /Object/Command/Attribute is not valid.
|
||
|
For example, 'help /cx add verify' is not a valid Help command string and the
|
||
|
system would respond with a list of all '/cx add' commands followed by an
|
||
|
error message.</p>
|
||
|
<p>An alternate way to use Help is with '?' or 'help' at the end of a command
|
||
|
string. That is, starting with the object, followed by the command, followed by '?' or
|
||
|
'help'. For example, '/c0' being our object and 'show' is our command:</p>
|
||
|
<pre>
|
||
|
//localhost> /c0 show ?
|
||
|
/cx show
|
||
|
/cx show Attribute [Attribute ...] where Attribute is:
|
||
|
allunitstatus|bios|firmware|driver|drivestatus|exportjbod|

|

numunits|unitstatus|ondegrade(9500S only)|spinup|stagger
|

/cx show all where all means Attributes and configurations.

<p><strong>Note:</strong> Again, Help stops at the command keyword level, so that
|
||
|
'/c0 show selftest help' or '/c0 show phy ?' would respond with an output
|
||
|
identical to <strong>/c0 show phy</strong> followed by <strong>/c0 show ?</strong>. In this case no
|
||
|
error follows. Please also note that if /c0 is not a valid controller in
|
||
|
your system, an error is generated and this way of using help would not
|
||
|
work. Instead you will get the following:</p>
|
||
|
<pre>
|
||
|
//localhost> /c4 show ?

Error: (CLI:003) Specified controller does not exist.</pre>

<h1><a name="features">Features</a></h1>
|
||
|
<p>This section lists some of the features that CLI supports for the 3ware RAID
|
||
|
product. While many system features require a few commands, some require or
|
||
|
involve a set of commands that work together. Also, some of these features
|
||
|
may be compenhensively more complex to described in a few discreet commands.
|
||
|
The purpose of this section is to provide an encapsulated view of selected
|
||
|
system features with their command set.</p>
|
||
|
<p>Please note that you could consult the <em>3ware SAS/SATA RAID Software User Guide</em>
|
||
|
for more in-depth conceptual information about features that can be used to
|
||
|
control your 3ware RAID controller as well.</p>
|
||
|
<p>The subsections which follow contain descriptions, the commands applicable, and
|

<h2><a name="drive_performance_monitor">Drive Performance Monitor</a></h2>
|
||
|
<p>Performance monitoring and statistics of the RAID controller, as a basis
|
||
|
for analysis of performance, may also provide information for qualification
|
||
|
and diagnostics. The Drive Performance Monitor of CLI supports statistics of
|
||
|
queue depths, IOPs, transfer rate, response time for reads/writes, and
|
||
|
command reads/writes.</p>
|
||
|
<p>Queue depth refers to the number of reads/writes currently outstanding,
|
||
|
IOPs refers to the number of reads/writes completing, transfer rate refers
|
||
|
to the number of sectors read/written, response time refers to the
|
||
|
execution time of all commands, and command read/writes refers to the
|
||
|
drive and drive sectors' accumlated read and write commands.</p>
|
||
|
<p>The types of drive performance statistics supported are organized into five
|
||
|
groups:</p>
|
||
|
<pre>
|
||
|
- instantaneous
|
||
|
- running average
|
||
|
- long command times
|
||
|
- response histogram
|
||
|
- extended drive statistics</pre>
|
||
|
<p>The instantaneous measurements provide a short duration average. The running
|
||
|
average is a measure of long-term averages that smooth out the data, and
|
||
|
results in older results fading from the average over time. The long command
|
||
|
times is a collection of the commands with the longest read/write
|
||
|
response time. The response histogram categorizes the read/write execution
|
||
|
times and group them together based on time frames. Finally, the extended
|
||
|
drive statistics refers to statistics of a drive's read commands, write
|
||
|
commands, write commands with FUA (Force Unit Access), flush commands, and
|
||
|
a drive sectors's read, write, and write commands with FUA.</p>
|
||
|
<p><strong>Note:</strong> This feature is for the 9550SX and higher model controllers, with
|
||
|
exception of the commands related to extended drive statistics, that are
|
||
|
supported on the 9650SE, 9690SA and 9750 controllers only.</p>
|
||
|
<p><strong>OPERATION</strong></p>
|
||
|
<p>The command syntax falls into three categories: 1) Configuration, 2) port-based
|
||
|
drive statistics, and 3) controller-based drive statistics summary. The
|
||
|
configuration category allows the user to see the settings as well as change them.
|
||
|
At this time, the only setting that the user can change is 'enable' or 'disable'
|
||
|
of the Drive Performance Monitor. The port-based 'show' commands provide
|
||
|
requested statistics based on type. The port-based 'set' command clears the
|
||
|
specified type statistics. While these commands require the specification of
|
||
|
the port each time, the controller-based commands do not and provide the
|
||
|
information in a summary format.</p>
|
||
|
<p><strong>Note:</strong> Please note that the keyword 'pmstat' and 'dpmstat' generate the same
|
||
|
system response. At this time both could be used for Drive Performance Monitor
|
||
|
statistics. In the future if other types of performance monitor support would
|
||
|
be added, 'pmstat' would denote Performance Monitor while 'dpmstat' would
|
||
|
refer to Drive performance statistics only.</p>
|
||
|
<p>The following table summarizes the drive performance monitor commands. The command
|
||
|
type, command syntax, and corresponding descriptions are listed. Following the
|
||
|
table is an important note, which is then followed by examples and usage of the
|
||
|
commands.</p>

--------------+-----------------------------------+-----------------------------------</pre>
|
||
|
<p><strong>Note:</strong> The command '/cx show dpmstat' shows the performance monitor
|
||
|
configuration and the default set of summary statistics (type=inst) shows data
|
||
|
regardless of whether the performance monitor setting is ON or OFF. If the setting
|
||
|
is ON and I/O is running, the statistics data will change over time because the
|
||
|
measurements are being averaged. If the setting is OFF, the same table layout is
|
||
|
shown. However, since no calculations are taking place, the data will be static
|
||
|
and remains unchanged. Thus, when the drive performance monitor is OFF, the data
|
||
|
shown may not be zeros.</p>
|
||
|
<p>Examples of the command's usage are shown below.</p>
|
||
|
<p>To display the configuration of the Drive Performance Monitor of the specified
|
||
|
controller (default statistics display is instantaneous data), use command
|
||
|
<strong>/cx show dpmstat</strong>. For example:</p>
|
||
|
<pre>
|
||
|
//localhost> /c0 show dpmstat
|

<p>In the configuration information above, 'Version' refers to the firmware version
|
||
|
of the Performance Monitor, 'Max commands for averaging' refers to the maximum number of
|
||
|
commands that can be saved and used for calculating the average, and 'Max latency
|
||
|
commands to save' refers to the maximum number of commands with high latency that
|
||
|
are saved. The number of elements in the buffer is determined by these configurations
|
||
|
and the memory constraints of the system.</p>
|
||
|
<p>To set the Drive Performance Monitor to 'enable' or 'disable', use commands
|
||
|
<strong>/cx set dpmstat=on</strong> and <strong>/cx set dpmstat=off</strong>, respectively.
|
||
|
For example:</p>
|
||
|
<pre>
|
||
|
//localhost> /c0 set dpmstat=off
|
||
|
Setting Drive Performance Monitoring on /c0 to [off]... Done.</pre>
|
||
|
<p>To display the running average statistics data at the controller
|
||
|
level, i.e., as a summary of the running average data for the set of
|
||
|
drives attached to the controller, use command <strong>/cx show dpmstat type=ra</strong>.
|
||
|
For example:</p>
|
||
|
<pre>
|
||
|
//localhost> /c0 show dpmstat type=ra

|

|
<p>To clear the running average statistics data of the specified port,

|
use command <strong>/cx/px set dpmstat=clear type=ra</strong>. For example:</p>

<pre>

//localhost> /c0/p3 set dpmstat=clear type=ra
|

|
Clearing Port Performance Monitor running average statistics on /c0/p3... Done.</pre>
|
||
|
<p>Please note that this clears the Running Average and Histogram data.</p>
|
||
|
<p><strong>Note:</strong> Usage of the 'clear' command without specifying 'type' implies
|
||
|
the default, which is 'type=ra'. The default thus effectively clears
|
||
|
both the running average statistics and histogram data. Also, some statistics
|
||
|
data types cannot be cleared, such as setting 'type=inst' or 'type=histdata'.
|
||
|
Attempting to clear these will return an error.</p>
|

|
<p>If I/O traffic to the drive has been stopped, after clearing, a

<h2><a name="rapid_raid_recovery">Rapid RAID Recovery</a></h2>
|
||
|
<p>Rapid RAID Recovery can speed up the rebuild, initialize, and verify processes
|
||
|
and tasks in response to an unclean system shutdown. Effectively this feature
|
||
|
provides for expedited boot-up time.</p>
|
||
|
<p>This feature is supported on the 9750, 9690SA and 9650SE (with supporting firmware)
|
||
|
controllers. Also, it is only supported on redundant arrays only, such as RAID-1,
|
||
|
RAID-5, RAID-6, RAID-10 and RAID-50. This feature is not supported over migration.</p>
|
||
|
<p><strong>OPERATION</strong></p>
|
||
|
<p>The usage of this feature consists of a set of commands that sets
|
||
|
the feature to one of three possible states. This configuration may be
|
||
|
defined at unit creation time or after a unit has been created. Below
|
||
|
is a summary of the commands for this feature.</p>
|
||
|
<pre>
|
||
|
/cx add ... rapidrecovery=all|rebuild|disable
|
||
|
/cx/ux set rapidrecovery=all|rebuild|disable [quiet]
|
||
|
/cx/ux show rapidrecovery</pre>
|
||
|
<p>If you set this option to <strong>all</strong>, upon an unclean system shutdown, the
|
||
|
Rapid RAID Recovery policy will apply to rebuild, initialize, and verify tasks at
|
||
|
reboot. If you set this option to <strong>rebuild</strong>, then only the rebuild task will
|
||
|
be applied. If you set it to <strong>disable</strong>, then none of the tasks will be sped up.
|
||
|
Please note that once this attribute is set for the unit, the policy setting
|
||
|
is persistent in the system until it is disabled.</p>
|
||
|
<p><strong>Note:</strong> Once the Rapid RAID Recovery has been ``disabled'' for a unit, it
|
||
|
cannot be changed again for that unit. As a result, if you issue the
|
||
|
'/cx/px set rapidrecovery=disable' command, a message along with a prompt for
|
||
|
input to proceed will appear. To turn off the message and prompt
|
||
|
for scripting purposes, use the quiet option.</p>
|
||
|
<p><strong>Note:</strong> The default setting of Rapid RAID Recovery is 'all' for redundant
|
||
|
arrays. For non-redundant arrays the default is disabled.</p>
|
||
|
<p>Consider a 9690SA controller with four drives attached. Creating a RAID-5
|
||
|
unit with the rapidrecovery attribute set to the <strong>all</strong> option:</p>
|
||
|
<pre>
|
||
|
//localhost> /c1 add type=raid5 disk=0:2:3 rapidrecovery=all</pre>
|
||
|
<pre>
|
||
|
Creating new unit on controller /c1 ... Done. The new unit is /c1/u0.
|

|
Setting default Command Queuing Policy for unit /c1/u0 to [on] ... Done.
|

|
||
|
Warning: You do not have a battery backup unit for /c1/u0 and the enabled
|

<h2><a name="user_defined_lun_sizing">User Defined LUN Sizing</a></h2>
|
||
|
<p>User Defined LUN Sizing, or, Variable LUN Carve, is a feature that allows
|
||
|
the user to specify variable sizes for volumes in a unit. The first volume
|
||
|
may be considered, although not necessarily, the Boot LUN. This feature
|
||
|
allows the user to specify up to four volumes or LUNs in a unit.</p>
|
||
|
<p>You can define the LUN sizes for these array types: RAID-0, RAID-1,
|
||
|
RAID-10, RAID-5, RAID-50, RAID-6 and Single.</p>
|
||
|
<p>To specify Variable LUN Carve simply requires setting an attribute during unit
|
||
|
creation. However, to eliminate potential confusion with the existing
|
||
|
autocarve and carvesize commands, this section was created to describe
|
||
|
this feature along with those commands.</p>
|
||
|
<p>If the pre-existing related commands are included, the set of LUN carve
|
||
|
commands are the following:</p>
|
||
|
<pre>
|
||
|
/cx add ... [v0=n|vol=a:b:c:d]
|
||
|
/cx show autocarve
|
||
|
/cx show carvesize
|
||
|
/cx set autocarve=on|off
|
||
|
/cx set carvesize=[1024..32768]</pre>
|
||
|
<p>Note that the first command associates with this feature, and the latter
|
||
|
four commands have pre-existed.</p>
|
||
|
<p>While the Variable LUN Sizing feature is related to the autocarve feature,
|
||
|
they are independent. If autocarve has been set to ON, then the sizes of
|
||
|
the volumes for that unit are set to the specifed carve-size (or the
|
||
|
default). The possible size of the carving is in the range of
|
||
|
{1024..32768} GB or {1..32} TB. Specifying the <code>size(s)</code> of the boot or
|
||
|
first four volumes in essense overlays these volumes with their respective
|
||
|
sizes to that of the carved volume sizes. For example, if the carvesize
|
||
|
has been set to 1024GB and autocarve is ON:</p>
|
||
|
<p>Autocarve=ON, carvesize=1024GB (1TB)</p>
|
||
|
<pre>
|
||
|
------+------+------+------+------+------+------+------+------+------+-------
|
||
|
1024 1024 1024 1024 1024 1024 1024 1024 1024 1024 . . .
|
||
|
------+------+------+------+------+------+------+------+------+------+-------</pre>
|
||
|
<p>If we specify the first four LUN volumes to be 2000GB, 500GB, 1024GB, and 700GB,
|
||
|
then we have the following:</p>
|
||
|
<pre>
|
||
|
------------+---+------+----+-----+------+------+------+------+------+-------
|
||
|
2000 500 1024 700 896 1024 1024 1024 1024 1024 . . .
|
||
|
------------+---+------+----+-----+------+------+------+------+------+-------</pre>
|
||
|
<p>All numbers are in units of GB. Note the while the last specified carved size
|
||
|
was 700GB, the next carved volume is not 1024GB but,</p>
|
||
|
<pre>
|
||
|
1024GB - (remainder of last volume carved)</pre>
|
||
|
<p>Or:</p>
|
||
|
<pre>
|
||
|
1024 - 128 = 896</pre>
|
||
|
<p>The remainder of the last volume is 128GB because the four specified volumes
|
||
|
totaled 4224GB which exceeds the four autocarved volumes totalling 4096GB
|
||
|
by 128GB.</p>
|
||
|
<p>For the add command, at unit creation time the volume sizes could be
|
||
|
specified with either the attribute <strong>v0=</strong> or <strong>vol=</strong>. With <strong>v0</strong> only
|
||
|
the first LUN volume size could be specified. With <strong>vol</strong>, up to four LUN
|
||
|
volume sizes may be specified. The input of size is an integer in
|
||
|
gigabytes (GB) and the valid range is [1..32768], the upper limit is 32TB.</p>
|
||
|
<p>If the <strong>vol=a:b:c:d</strong> attribute is used, each volume is separated by the
|
||
|
symbol <strong>:</strong> in ascending order. That is, the integer closest to <strong>=</strong> is
|
||
|
volume 0 (v0), followed by volume 1 (v1), volume 2 (v2), etc. The maximum
|
||
|
that could be specified with this method is four volumes, or, up to v3.</p>
|
||
|
<p>For example, consider an 8-port controller with four drives attached. As
|
||
|
in the following:</p>

<h2><a name="verify">Verify</a></h2>
|
||
|
<p>The Verify function is among other self-test functions such as Rebuild and
|
||
|
Selftest in the RAID system. It performs data integraty checks on an array
|
||
|
unit based on the unit type. For a RAID-1 array, for example, the verification
|
||
|
involves checking that both drives contain the exact data; and on a RAID-5
|
||
|
array, the parity information is used to verify data integrity.</p>
|
||
|
<p>This feature is available on 9000 series controllers. The Verify function
|
||
|
requires some initial setup. Particularly the scheduled time windows of
|
||
|
the background verify tasks need to be defined. A scheduled time window,
|
||
|
or, timeslot, is part of the Verify Schedule.</p>
|

|
<p><strong>SET UP</strong></p>
|
||
|
<p>For the <strong>Verify</strong> function, the following commands are used for the
|
||
|
set up:</p>
|
||
|
<pre>
|
||
|
/cx set verify=enable|disable|1..5
|
||
|
/cx add verify=ddd:hh:duration
|
||
|
/cx del verify=slot_id</pre>
|
||
|
<p>The setup consists of setting Verify to enable, then adding verify
|
||
|
timeslots into the Schedule. The Schedule contains a default set of verify
|
||
|
timeslots defined, so specifying the verify timeslots is not necessary if
|
||
|
the defaults are suitable.</p>
|
||
|
<p>When a verify background process would initiate and run depends on more
|
||
|
than the Schedule itself. The sections below describe this in more detail.</p>
|
||
|
<p><strong>AUTOVERIFY</strong></p>
|
||
|
<p>Related to this Verify function is <strong>autoverify</strong>. The Autoverify setting lets
|
||
|
the RAID firmware determine a time to start the verify process of a unit
|
||
|
automatically or at its discretion at a time suitable (but related to the
|
||
|
Schedule) when it is set to ON. If a verify process has started and the verify
|
||
|
task cannot complete within the scheduled window, the verify task would be
|
||
|
paused and resumed later. Again, firmware makes its decision autonomously
|
||
|
based on factors such as the schedule, settings, and other higher priority
|
||
|
background tasks.</p>
|
||
|
<p>Autoverify applies to 9000 series controllers also.</p>
|
||
|
<p>The commands associated with Autoverify are the following:</p>
|
||
|
<pre>
|
||
|
- /cx/ux set autoverify=on|off
|
||
|
- /cx/ux show autoverify</pre>
|
||
|
<p>Autoverify is also an attribute that could be set at unit creation. The
|
||
|
setting of autoverify is ON if Basic Verify (see <strong>Verify - Basic</strong> section)
|
||
|
is supported, otherwise the default is set to OFF.</p>
|
||
|
<p><strong>MANUAL VERIFY</strong></p>
|
||
|
<p>Also related to the Verify function is Manual verify, where a background
|
||
|
verify process or task for a unit could be started and stopped manually.
|
||
|
The following is the set of commands associated with this:</p>
|
||
|
<pre>
|
||
|
/cx/ux start verify
|
||
|
/cx/ux stop verify</pre>
|
||
|
<p>Note that if subsequent to this command, one enables the background verify
|
||
|
task to follow the scheduled slots, then this on-demand task will be paused
|
||
|
until the next scheduled timeslot.</p>
|
||
|
<p><strong>VERIFY STATUS</strong></p>
|
||
|
<p>Finally, to see the status of the tasks associated with the Verify function,
|
||
|
the set of commands for that is the following:</p>
|
||
|
<pre>
|
||
|
show verify
|
||
|
/cx show verify
|
||
|
/cx/ux show verifystatus
|
||
|
/cx/ux show autoverify</pre>
|
||
|
<p>Here is an example of the show verify command.</p>
|
||
|
<pre>
|
||
|
//localhost> /c2 show verify</pre>

<h2><a name="verify__advanced">Verify - Advanced</a></h2>
|
||
|
<p>Advanced Verify is actually the Verify function of the previous section, intended
|
||
|
for advanced users, in systems where Basic Verify is supported. Advanced/Basic
|
||
|
Verify is supported on 9650SE and 9690SA controllers. In such systems, to set
|
||
|
to Advanced Verify as opposed to Basic Verify, you would set verify=advanced
|
||
|
with the command:</p>
|
||
|
<pre>
|
||
|
/cx set verify=advanced|basic|1..5</pre>
|
||
|
<p>If the system does not support Advanced/Basic Verify, you would get the following
|
||
|
error:</p>
|
||
|
<pre>
|
||
|
//localhost> /c2 set verify=advanced
|
||
|
Error: (CLI:146) Basic/Advanced Verify is not supported.</pre>
|
||
|
<p>In this case you could still set Verify to enable/disable. (See previous section.)
|
||
|
If Advanced/Basic is supported on your system, after issuing this command, all other
|
||
|
commands for Advanced Verify is identical to Verify that was presented in the previous
|
||
|
section.</p>
|
||
|
<p>We will show a setup scenario to demonstrate how the commands are used with respect
|
||
|
to this feature. For a RAID system with the following arrays and drives, we will
|
||
|
show the usage of the commands along with examples. Please note that this system
|
||
|
has a 9690SA controller with the firmware that also supports Basic Verify.</p>

<h2><a name="verify__basic">Verify - Basic</a></h2>
|
||
|
<p>As a result of the complexity and non-deterministic nature of Verify or
|
||
|
Advanced Verify with respect to when scheduled verify tasks may execute, the
|
||
|
Basic Verify feature was introduced to provide a more simplistic verify
|
||
|
function as an option.</p>
|
||
|
<p>Basic Verify does not change the current Verify function. But supplies the
|
||
|
user a means to specify a preferred day and time for a weekly background verify
|
||
|
task to be executed. If the preferred day and time is not specified, a default
|
||
|
is provided. The setting is simplier and when a scheduled verify task would
|
||
|
run is more deterministic and straight-forward.</p>
|
||
|
<p>Before using Basic Verify, it is important to know if your system supports
|
||
|
Advanced/Basic Verify. Generally, this is supported in the 9650SE, 9690SA and 9750
|
||
|
controllers. If the system does not support Advanced/Basic Verify, you would get
|
||
|
the following error:</p>

<h2><a name="metacharacter_warning_">Meta-Character Warning:</a></h2>
|
||
|
<p>If you wish to use CLI in single command mode (not interactive), make sure to avoid
|
||
|
collision with your command interpreter (OS shell) by escaping the meta-characters
|
||
|
(such as ?, <, >, @, &, *, etc) appropriately with single quote around them.</p>
|
||
|
<p>For example, given the</p>
|
||
|
<p>$ tw_cli /c0 ?</p>
|
||
|
<p>This is a case of single command usage where the user intends to get help on Controller
|
||
|
related commands. While this is a valid CLI command, but since the arguments to CLI
|
||
|
are first processed by the shell, then some shells like <code>csh(1)</code> will interpret the '?' as
|
||
|
a meta-character to be used toward file completion and if no file is found with a single
|
||
|
character, then shell will complain before the arguments are even passed down to CLI.</p>
|
||
|
<p>One solutions of this problem can be :</p>
|
||
|
<p>$ tw_cli help /cx</p>
|
||
|
<p>or</p>
|
||
|
<p>$ tw_cli '/c0 ?'</p>

<h2><a name="reporting_style">Reporting Style</a></h2>
|

<pre>
|

|
|

|
tw_cli(8) reporting has changed (hopefully for better). The intent has been to
|
||
|
provide a consistent tabular reporting so that relevant and important information
|
||
|
(such as B<info>) are made available as fast as possible. For example, firmware,
|
||
|
PCB, PCHIP and similar information have been removed from the info summary report,
|
||
|
as this type of information is not frequently needed.</pre>
|
||
|
<p>The new style also accommodates automation much better by providing consistent
|
||
|
columns with or without values so that it could be easily parsed. The intent is
|
||
|
to make CLI yet another API (to approach it).</p>
|
||
|
<p>However to accommodate current automations around tw_cli and to ease the migration,
|
||
|
the old behavior can still be requested by setting <strong>TW_CLI_STYLE</strong>
|
||
|
environment variable to <strong>OLD</strong> as follows:</p>
|
||
|
<pre>
|
||
|
If Bash, then "export TW_CLI_STYLE=OLD"
|
||
|
If csh, then "setenv TW_CLI_STYLE OLD"
|
||
|
if Windows, then "set TW_CLI_STYLE=OLD"</pre>
|
||

<p>This backward compatibility window, will be communicated by official 3ware representatives.</p>

<h2><a name="initialization_process_control">Initialization Process Control</a></h2>
|

|
<p>On the 9K series of controllers, the rebuild scheduling controls both rebuild and
|
||

initialize processes if it is enabled. Currently, <code>tw_cli(8)</code>
|
||
|
does not have any direct command to pause or resume an initialization process.
|

If such action is needed, use the rebuild scheduling to handle it.</p>
