NAME
     mlxcontrol -- Mylex DAC-family RAID management utility

SYNOPSIS
     mlxcontrol <command> [args]
     mlxcontrol status [-qv] [drive]
     mlxcontrol rescan controller [controller ...]
     mlxcontrol detach drive [drive ...]
     mlxcontrol detach -a
     mlxcontrol check drive
     mlxcontrol config controller
     mlxcontrol help command

DESCRIPTION
     The  mlxcontrol utility provides status monitoring and management functions
     for devices attached to the mlx(4) driver.

     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.

     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 -v flag, display much more verbose informa-
	      tion.  With the -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.

     rescan   Rescan  one  or  more  controllers  for non-attached system drives
	      (e.g. drives that have been detached or created subsequent to dri-
	      ver initialisation).  If the -a flag is supplied, rescan all  con-
	      trollers in the system.

     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  -a  flag is supplied, detach all system drives from the nomi-
	      nated controller.

     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 imme-
	      diately; use the status command to monitor  the  progress  of  the
	      check.

     rebuild  Requires	two  arguments, controller and physdrive as specified in
	      the output of the status command.  All system drives  using  space
	      on  the  physical  drive 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
	      status command to monitor the progress of the rebuild.

     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.

     help     Print usage information for command.

     tion.

     Error log extraction is not yet supported.
