Troubleshooting MPIO
Verifying DSM for MPIO operations
After logging on to a volume via iSCSI, the DSM for MPIO automatically builds a data path to
each storage system in the cluster and one administrative path. You can verify the DSM for MPIO
operations by looking at the Details window of the iSCSI connection for the volume after logging
on to that volume.
Figure 8 Verifying the DSM for MPIO connections
What happens if a path fails with the 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 Figure 9 (page 11).
