DG creation fails with error “V-5-1-585 Disk group punedatadg: cannot create: SCSI-3 PR operation failed” on the VSCSI disks (3875044)

If the disks that do not support SCSI3 PR are used to create the shared disk group, the operation fails as the data disk fencing functionality cannot be provided on such disks. The operation fails with error:

VxVM vxdg ERROR V-5-1-585 Disk group <DGNAME>: cannot create: SCSI-3 PR operation failed

Workaround:

If you still want to allow such disks to be part of shared disk group, disable the data disk fencing functionality in the cluster by running the command on all the nodes in the cluster:

# vxdctl scsi3pr off
<!--NeedCopy-->

After the disabling process, take caution that it may not protect the disks against the ghost I/Os from nodes that are not part of the cluster.
