8.11.4 SC Series back-end outage
If an unplanned event impacts primary Live Volume back-end SC Series components (such as the loss of
several drives or a drive shelf), the primary Live Volume will automatically fail over to the surviving array. Both
arrays will continue to service I/O requests from the primary Live Volume locally and remotely through the
replication link.

If an unplanned event impacts the availability of the tiebreaker service on the DSM server, both SC Series
arrays will continue to service I/O requests but no automatic failover can occur during this time.
