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 func-
     tions 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 num-
     ber 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 ver-
	      bose information.  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
	      driver initialisation).  If the -a flag is supplied, rescan all
	      controllers 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 sys-
	      tem drive (e.g. RAID1 or RAID5).	The controller will scan the
	      system drive and repair any inconsistencies.  This command
	      returns immediately; 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 sys-
	      tem drives from a configuration in a future release.

     help     Print usage information for command.
