+.SH NAME
+megactl \- diagnostics on megaraid adapters and attached disks.
+.SH SYNOPSIS
+megactl [\fB-vest\fP] [\fB-H\fP] [\fB-l\fP log-page-nr] [\fB-T\fP long|short] [target \.\.\.]
+.PP
+Reports diagnostics on megaraid adapters and attached disks. Permits
+dumping of controller log pages for inspection of error, temperature,
+and self-test conditions, initiates self-test diagnostics, and documents
+adapter and logical drive configuration. Target devices may be adapters,
+(e.g. a0), channels (e.g. a0c0), or individual disks (e.g. a0c0t0). If
+no target is specified, reports configuration and drive state on all
+adapters. If a target matches a collection of disks, operations are
+applied to all matching devices. Options are:
+.TP
+.B
+\fB-v\fP
+Increase program verbosity.
+.TP
+.B
+\fB-e\fP
+Dump read (0x03), write (0x02), and verify (0x05) error log
+pages.
+.TP
+.B
+\fB-s\fP
+Dump self-test (0x10) log page.
+.TP
+.B
+\fB-t\fP
+Dump temperature (0x0d) log page.
+.TP
+.B
+\fB-l\fP page
+Dump the specified log page. Log page 0 documents the log pages
+the device supports.
+.TP
+.B
+\fB-p\fP
+Do not report physical disks. Reports only adapters and logical
+drives. Useful for concisely documenting adapter configuration.
+.TP
+.B
+\fB-T\fP test
+Initiate the background short or long self-test procedure. The
+test may take up to an hour to complete, but does not inhibit
+access to the device. The test may be monitored using the \fB-s\fP
+option.
+.TP
+.B
+\fB-H\fP
+Perform an adapter health check. Inspects state of all logical
+and physical drives and battery backup unit and reports problem
+conditions. If all is well, generates no output. Useful in a
+cron job.
+.TP
+.B
+\fB-B\fP
+When performing health check, do not treat battery problems as
+failures.
+.TP
+.B
+\fB-V\fP
+Show version.
+.PP
+N.B. The background long self test is a useful tool for diagnosing
+problems with individual disks. But be cautious with program usage.
+"megactl \fB-T\fP long" with no targets will initiate a background long self
+test on every drive on every adapter. This may not be what you want.
+.PP
+By default, the health check option inspects log pages 0x02, 0x03, and
+0x05 for uncorrected read, write, and verify errors, 0x0d for excess
+temperature conditions, and 0x10 for failed self tests. If, however, any
+of the log page options is specified, only the designated log pages are
+inspected.
+.PP
+This program requires the device file /dev/megadev0 to be present on
+the system. If your system does not have this device file, you may
+create it either by executing Dell's "dellmgr" program once, or by
+locating the megadev entry in /proc/devices and creating /dev/megadev0
+as a character device with suitable permissions with a matching major
+device number and a minor number of 0.

+.SH NAME
+megasasctl \- diagnostics on megaraid adapters and attached disks.
+.SH SYNOPSIS
+megasasctl [\fB-vest\fP] [\fB-H\fP] [\fB-l\fP log-page-nr] [\fB-T\fP long|short] [target \.\.\.]
+.PP
+Reports diagnostics on megaraid adapters and attached disks. Permits
+dumping of controller log pages for inspection of error, temperature,
+and self-test conditions, initiates self-test diagnostics, and documents
+adapter and logical drive configuration. Target devices may be adapters,
+(e.g. a0), enclosures (e.g. a0e0), or individual disks (e.g. a0e0s0). If
+no target is specified, reports configuration and drive state on all
+adapters. If a target matches a collection of disks, operations are
+applied to all matching devices. Options are:
+.TP
+.B
+\fB-v\fP
+Increase program verbosity.
+.TP
+.B
+\fB-e\fP
+Dump read (0x03), write (0x02), and verify (0x05) error log
+pages.
+.TP
+.B
+\fB-s\fP
+Dump self-test (0x10) log page.
+.TP
+.B
+\fB-t\fP
+Dump temperature (0x0d) log page.
+.TP
+.B
+\fB-l\fP page
+Dump the specified log page. Log page 0 documents the log pages
+the device supports.
+.TP
+.B
+\fB-p\fP
+Do not report physical disks. Reports only adapters and logical
+drives. Useful for concisely documenting adapter configuration.
+.TP
+.B
+\fB-T\fP test
+Initiate the background short or long self-test procedure. The
+test may take up to an hour to complete, but does not inhibit
+access to the device. The test may be monitored using the \fB-s\fP
+option.
+.TP
+.B
+\fB-H\fP
+Perform an adapter health check. Inspects state of all logical
+and physical drives and battery backup unit and reports problem
+conditions. If all is well, generates no output. Useful in a
+cron job.
+.TP
+.B
+\fB-B\fP
+When performing health check, do not treat battery problems as
+failures.
+.TP
+.B
+\fB-V\fP
+Show version.
+.PP
+N.B. The background long self test is a useful tool for diagnosing
+problems with individual disks. But be cautious with program usage.
+"megasasctl \fB-T\fP long" with no targets will initiate a background long self
+test on every drive on every adapter. This may not be what you want.
+.PP
+By default, the health check option inspects log pages 0x02, 0x03, and
+0x05 for uncorrected read, write, and verify errors, 0x0d for excess
+temperature conditions, and 0x10 for failed self tests. If, however, any
+of the log page options is specified, only the designated log pages are
+inspected.
+.PP
+This program requires the device file /dev/megaraid_sas_ioctl_node to be
+present on the system. If your system does not have this device file,
+you may create it either by executing LSI's "MegaCli" program once,
+or by locating the megadev_sas_ioctl entry in /proc/devices and creating
+/dev/megaraid_sas_ioctl_node as a character device with suitable
+permissions with a matching major device number and a minor number of 0.
