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 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 nominated 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 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 system
	      drives from a configuration in a future release.

     help     Print usage information for command.

BUGS

     The config command does not yet support modifying system drive configuration.

     Error log extraction is not yet supported.

NAME

     ida -- Compaq Intelligent Drive Array Controllers

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device ida

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   ida_load="YES"

DESCRIPTION

     The Compaq Intelligent Drive Array (IDA) technology is used to distribute data across an array of hard drives.  It unites these hard drives
     into one or more high-performance logical drives.	The drive array is managed by an array controller.

     These controllers have the ability to provide fault tolerance for the connected drives and optionally provide write cache for the logical
     drives.  It is also possible for an application to access the SCSI bus subsystem directly by using the pass-through interface.

HARDWARE

     The following controllers are supported by the ida driver:

     o	 Compaq SMART Array 221
     o	 Compaq Integrated SMART Array Controller
     o	 Compaq SMART Array 4200
     o	 Compaq SMART Array 4250ES
     o	 Compaq SMART 3200 Controller
     o	 Compaq SMART 3100ES Controller
     o	 Compaq SMART-2/DH Controller
     o	 Compaq SMART-2/SL Controller
     o	 Compaq SMART-2/P Controller
     o	 Compaq SMART-2/E Controller
     o	 Compaq SMART Controller

IMPLEMENTATION NOTES

     Extreme caution should be exercised when using the pass-through interface.  It is possible to interfere with normal system I/O and cause
     hangs if pass-through is used to an active device.  Pass-through should only be used to a device that is otherwise quiescent.
