Hope someone can help, we have an old PS5000 (out of support) which has 16 disks in raid 10. 14 of them make up the raid group, of which one has failed, however the two "spare" disks are simply marked as offline.
There doesn't seem to be any issues with them other than this, I just can't find a way from gui or command line to set them online and as spare disks so they can be used for the rebuild. I haven't done any physical removal/swapping of drives yet.
Any thoughts appreciated.
