Disk Group Quarantine Issue After Replacing a Disk on HPE MSA

[abzalsoltankhan]

Hi everyone! Here’s the situation: There are two MSA2060-ENCL-SFF storage systems with MSA-12G-ENCL-LFF expansion shelves, one is old and the other is new. The old one is currently turned off. Both storage systems have Pool B with Disk Groups dgB01. On the expansion shelf of the old storage system, we needed to replace the fifth disk, so we replaced it with a disk from the old expansion shelf of the old system. The disk appeared in the system, but it is listed as an Unassociated Disk in Disk Groups (dgB01).

Here is the output from the CLI:

# show disk-groups

   --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
   The spare capacity available to the MSA-DP+ disk group is not sufficient to meet the required configured spare capacity that is needed to provide full fault tolerance. Spare capacity availability can be influenced by operations that require available space in the system, such as reconstructing data from a failed disk.
  - Add disks to the disk group, or replace any disks that may have failed. The system will automatically increase the spare capacity to meet the requirements placed on the system by the target spare capacity.

   The disk group is quarantined. - Look for events in the event log related to quarantine (172, 485, or 590), and follow the recommended actions for those events.

As I understand it, it has read the metadata from the disk that was replaced from the old storage system with the same Disk Groups, and now it shows this Disk Group as quarantined. What can be done here?

If you can return the drive to the other system and remove the disk-group metadata on the disk, that would be the easiest way to clear the disk.
If you are unable to complete that task then you will need to contact HPE support and request an escalation.  Clearing disk-metadata can be a very dangerous task, while this case seems to be straight forward, the initial levels of support are not supposed to be able to clear the metadata as a wrong step could permanently remove all data from the system.
FYI - more than likely the other system will also have problems that may require escalated support to recover, so it would be good to get both systems in a usable state sooner rather than later.
