Failure of a Multihost Disk Expansion Unit

If you lose power to one of the multihost disk expansion units, your volume management software detects errors on the affected disks and takes action to put them into an error state. Disk mirroring masks this failure from the Sun Cluster fault monitoring. No switchover or takeover occurs.

When power is returned to the multihost disk expansion unit, perform the procedure documented in Chapter 11, Administering SPARCstorage Arrays, or Chapter 12, Administering Sun StorEdge MultiPacks and Sun StorEdge D1000s.
