We just need to get the LUN up again, if all data is lost - that's OK. It's an old XSAN we can wipe/reinitialize.
So if there is no way to restore the missing LUN/RAID config from the drives (?) now in unconfigured mode, that means "redoing" the config for those drives/that LUN.
I downloaded/Exported the "configscript" from the controller and it is missing the LUN3 config. It seemed easy to just add the LUN3 settings back in by copying and add one of the other LUN's configs in and then edit it to what it must have been and then Import the now complete "configscript" to the controller. In the "configscript" it says you must delete the old "configscript" in the controller so it seems it not just overwriting the old file when you do an Import.
Does any of you guys know how to do this?
Either recovering the "Unconfigured" drives (RAID5 degraded by one drive) LUN / RAID5 or just "update" the "configscript" and reboot?.
