mlxctl

MLXCTL(8)						    BSD System Manager's Manual 						 MLXCTL(8)

NAME

     mlxctl -- Mylex DAC960 family management utility

SYNOPSIS

     mlxctl [-f dev] [-v] [-a] status [drive] [...]
     mlxctl [-f dev] [-a] detach [drive] [...]
     mlxctl [-f dev] [-a] check [drive] [...]
     mlxctl [-f dev] rebuild channel:target
     mlxctl [-f dev] cstatus
     mlxctl [-f dev] rescan
     mlxctl [-f dev] config

DESCRIPTION

     The mlxctl utility performs status monitoring and management functions for Mylex DAC960 RAID controllers and attached devices.

     The following options are available:

     -a       Apply the action to all drives attached to the controller.

     -f dev   Specify the control device to use.  The default is /dev/mlx0.

     -v       Increased verbosity.

     The following commands are available:

     cstatus  Display the controller's current status.

     status   Display the status of the specified drives.  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   Re-scan the logical drive table, and attach or detach devices from the system as necessary.

     detach   Detach the specified drives.  Drives must be unmounted and unopened for this command to succeed.

     check    Initiate a consistency check and repair pass on a drive that provides redundancy (e.g., RAID1 or RAID5).	This command returns imme-
	      diately.	The status command can be used to monitor the progress of the check.

     rebuild  Rebuild onto the specified physical drive.  Note that there can be only one running rebuild operation per controller at any given
	      time.  This command returns immediately.	The cstatus command can be used to monitor the progress of the rebuild.

     config   Write the current system drive configuration to stdout.

EXAMPLES

     Display the status of drive ld3 attached to the controller mlx1:

	   mlxctl -f /dev/mlx1 -v status ld3

SEE ALSO

     ld(4), mlx(4)

HISTORY

     The mlxctl command first appeared in NetBSD 1.5.3, and was based on the mlxcontrol utility found in FreeBSD.

BUGS

     Modifying drive configuration is not yet supported.

     Some commands do not work with older firmware revisions.

     Error log extraction is not yet supported.
