Unknown storage system

Symptom
HP Command View EVA reports an unknown storage system for a storage system that should be
displayed.
Cause of the error
HP Command View EVA may have lost communication with the controllers. Two possible scenarios
are:
• The HBA in the management server may have timed out commands to the controllers. See
storage system—cause
• The controllers are running a version of XCS that HP Command View EVA does not recognize.

When the fabric is heavily loaded, the FC adapter in the management server may time out commands
to the controllers. If this occurs, the storage system appears in the Unknown state.
