Troubleshooting MPIO Verifying P4000 DSM for MPIO operations After logging on to a volume via iSCSI, the P4000 DSM for MPIO automatically builds a data path to each storage system in the cluster and one administrative path.

Verifying P4000 DSM for MPIO operations
After logging on to a volume via iSCSI, the P4000 DSM for MPIO automatically builds a data path
to each storage system in the cluster and one administrative path. You can verify the P4000 DSM for
MPIO operations by looking at the Details window of the iSCSI connection for the volume after logging
on to that volume.

What happens if a path fails with the P4000 DSM for MPIO
If one I/O path fails, volume I/O continues because additional active I/O paths to the iSCSI SAN
remain, as illustrated in
