.Sh NAME
.Nm mlxcontrol
.Nd Mylex DAC-family RAID management utility
.Sh SYNOPSIS
.Nm mlxcontrol
.Aq command
.Op args
.Nm mlxcontrol
status
.Op Fl qv
.Op Ar drive
.Nm mlxcontrol
rescan
.Ar controller
.Op Ar controller ...
.Nm mlxcontrol

.Ar drive
.Op Ar drive ...
.Nm mlxcontrol
detach
.Fl a
.Nm mlxcontrol
check
.Ar drive
.Nm mlxcontrol
config
.Ar controller
.Nm mlxcontrol
help
.Ar command
.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 status
.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 (eg. 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 (eg. 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 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
.Ar command.
.Sh BUGS
The
.Ar config
command does not yet support modifying system drive configuration.
.Pp
Error log extraction is not yet supported.
.Sh AUTHORS
The mlxcontrol utility was written by
.An Michael Smith
.Aq msmith@FreeBSD.org .
