Stale SCSI-3 PR keys remain on disk after stopping the cluster and deporting the disk group

December 9, 2025

When all nodes present in the Arctera InfoScale cluster are removed from the cluster, the SCSI-3 Persistent Reservation (PR) keys on the data disks may not get preempted. As a result, the keys may be seen on the disks after stopping the cluster or after the nodes have booted up. The residual keys do not impact data disk fencing as they will be reused or replaced when the nodes rejoin the cluster. Alternatively, the keys can be cleared manually by running the vxfenclearpre utility.

For more information on the vxfenclearpre utility, see the Arctera InfoScale Administrator’s Guide.
