Unknown Storage System; No Storage Systems Found - HP 6400/8400 Software Manual

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.
See "Unknown storage system—cause
Unknown storage system—cause 1
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.
Corrective Action for Unknown Storage System—Cause 1
This scenario should correct itself in less than one minute. Alternately, you can perform a Rediscover
operation to initiate new commands to the controller.
Unknown storage system—cause 2
HP Command View EVA can only manage controllers that are running supported XCS versions.
Corrective Action for Unknown Storage System—Cause 2
Ensure that you are running the HP Command View EVA version that is compatible with XCS
09522000. See the "HP Command View EVA interoperability support" table in the HP StorageWorks
Enterprise Virtual Array compatibility reference to determine which version of HP Command View
EVA you should be running. Then, upgrade HP Command View EVA to a compatible version. See
"Required documentation" on page 11 for the link to this document.
