HP MSA Events Description Reference Guide (762785-001, March 2014)

Event descriptions 19
116
Error After a recovery, the partner controller was killed while mirroring write-back cache data to the controller
that logged this event. The controller that logged this event restarted to avoid losing the data in the partner
controller’s cache, but if the other controller does not restart successfully, the data will be lost.
Recommended actions
• To determine if data might have been lost, check whether this event was immediately followed by
event 56, closely followed by event 71; the failover indicates that the restart did not succeed.

Recommended actions
