Wrench Sun Storage Tek 2540 M2 controller lockdown
hello all,

I have recently acquired the above server and i am having issues with the RAID controllers being put into a lockdown state.
This occurs when new drives are added to the array, the controller automagically reboots and then gives status codes OE and LT. After this i am unable to communicate at all with the controllers.

So far i have connected to the arrays successfully using CAM with no drives in, but when the drives are added CAM loses communication with the array/controllers.

If anyone has any experience with these arrays, is there a preferred method of installing HDD's into the array, or is there any way to remove the lockdown state from the controller?

Any help wold be greatly appreciated Smilie

mlxcontrol

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

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.
