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 :frowning:
