After changing iSCSI storage array, RHEVH nodes become non-operational when attaching the storage domains and StoragePoolMasterNotFound errors appearing in vdsm.log

Solution Verified - Updated -

Issue

A complete power outage caused the RHEV environment and iSCSI SAN storage to go down.  Upon regaining power, the storage array wouldn't start due to a hardware issue.  The disks were taken out of the storage array and put into another storage array.  Upon starting the RHEV environment, the RHEVH nodes come up and appear as Up in the RHEVM, but when trying to attach the storage domain they become non-operational.
