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 m ay have timed out commands to the controllers. See

"Unknown storage sy stem—cause 1" on page 64 below.

• The controllers are running a version of XCS that HP Command View EVA does not recognize.

See "Unk

nownstoragesystem—cause2" on page 64.

Unknown storage system—cause 1

When the fabric is heavily loaded, the FC adapter in the management server may time out com m ands 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 c a n perform a Rediscover

operation to initiate new commands to the controller.

Unknown storage system—cause 2

HP Comm

and View EVA can only manage controllers that are running supported XCS versions.

Correc

tive Action for Unknown Storage System—Cause 2

Ensure that you are running the HP Command View EVA version that is compatible with XCS 6.110. See

the “EVA software version compatibility” table in the HP StorageWorks EVA software compatibility

reference to determine which version of HP Command View EVA you should be running. Then, upgrade

HP Command View EV A to a compatible version . See "Required documentation"onpage11forthe
