We're preparing a FAS9000 for an ONTAP upgrade and we have several broken disks that belong to pool NONE and therefore they do not have an owner. The disk model is EOS and it's not going to be replaced.
We wanted to unassign those disks but as they do not have an owner we don't know what we should do. Would it be possible to add them to FAILED pool? Would that assign an owner to the disk? Is it safe to remove the disks as they are (pool NONE, no owner) without doing anything to guarantee the ONTAP upgrade must be performed?
Thanks in advance for your help.
