P2000 G3: adding a new disk as spare fails

Hallo,

after I replaced a failed disk in the P2000 G3, I'm not able to defined the new disk a spare. Everytime I try to assign the disk a spare (select vdisk use manu Configuration > Manage Dedicated Spares) the procedure finished successfully (Message text: The vdisk spare settings were modified successfully.) and the disk is shown as "Spare".

But a few seconds later, the status if teh disk reverts back to AVAIL.

This is the same if I perform this action with the cli command (set spares disks 2.25 vdisk VDISK_D)

Attached you find the Event Log.

Any suggestions?

I do not see anything wrong.

kind regards Bernd
