Disconnects by removing the path (volume path) between the volume and the compute node. Before you run the command, verify that no I/O operation is being performed between the intended compute node and the intended volume.
When you are using Universal Replicator, note the following:
- Volume paths between a volume whose universalReplicatorAttribute is "P-VOL" or "S-VOL" and a compute node can be removed by deleting the Universal Replicator pair.
-
When compute nodes are clustered and the volumes recognized by the compute nodes are online, set the intended volume offline and then cancel allocation of the volume.
-
For FC* or iSCSI connection, before you delete path information from a compute node, verify whether the volumes that can be accessed from the compute node are in SCSI-2 Reserve status or SCSI-3 Persistent Reserve status. If the volumes are in either status, release them from the status, and then delete path information.
* Only the bare metal model is supported.
-
When you change the path information of a compute node, perform a rescan of the storage on that compute node. If the path information already deleted remains on the compute node, it might cause malfunction.
