.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility provides status monitoring and management functions
|
|
for devices attached
|
|
to the
|
|
.Xr mlx 4
|
|
driver.
|
|
.Pp
|
|
Controller names are of the form "mlxN"
|
|
where N is the unit number of the controller.
|
|
Drive names are of the form "mlxdN"
|
|
where N is the unit number of the drive.
|
|
Do not specify the path to a device node.
|
|
.Pp
|
|
.Bl -tag -width rebuild
|
|
.It status
|
|
Print the status of controllers and system drives.
|
|
If one or more drives are specified,
|
|
only print information about these drives,
|
|
otherwise print information
|
|
about all controllers and drives in the system.
|
|
With the
|
|
.Fl v
|
|
flag, display much more verbose information.
|
|
With the
|
|
.Fl q
|
|
flag, do not print any output.
|
|
This command returns
|
|
0 if all drives tested are online,
|
|
1 if one or more drives are critical and
|
|
2 if one or more are offline.
|
|
.It rescan
|
|
Rescan one or more controllers for non-attached system drives
|
|
(e.g.\& drives that have been
|
|
detached or created subsequent to driver initialisation).
|
|
If the
|
|
.Fl a
|
|
flag is supplied, rescan all controllers in the system.
|
|
.It detach
|
|
Detach one or more system drives.
|
|
Drives must be unmounted
|
|
and not opened by any other utility for this command to succeed.
|
|
If the
|
|
.Fl a
|
|
flag is supplied, detach all system drives from the nominated controller.
|
|
.It check
|
|
Initiate a consistency check and repair pass on a redundant system drive
|
|
(e.g.\& RAID1 or RAID5).
|
|
The controller will scan the system drive and repair any inconsistencies.
|
|
This command returns immediately;
|
|
use the
|
|
.Ar status
|
|
command to monitor the progress of the check.
|
|
.It rebuild
|
|
Requires two arguments,
|
|
.Ar controller
|
|
and
|
|
.Ar physdrive
|
|
as specified in the
|
|
output of the
|
|
.Ar status
|
|
command.
|
|
All system drives using space on the physical drive
|
|
.Ar physdrive
|
|
are rebuilt, reconstructing all data on the drive.
|
|
Note that each controller can only perform one rebuild at a time.
|
|
This command returns immediately; use the
|
|
.Ar status
|
|
command to monitor the progress of the rebuild.
|
|
.It config
|
|
Print the current configuration from the nominated controller.
|
|
This command will be updated
|
|
to allow addition/deletion of system drives from a configuration
|
|
in a future release.
|
|
.It help
|
|
Print usage information for
|
|
