Loading an iSCSI Storage cluster fails. How do I resolve this?

Solution

Try the following approaches:
Verify that all hosts in the cluster can recognize the same LUN device information.

Run multipath -ll to check whether the multipath output is consistent across all hosts.
If the output is inconsistent, run service multipathd restart on the affected host to restart the multipath service.
Run rescan-scsi-bus.sh -a to rescan the SAN storage.
Reload the iSCSI Storage cluster.
