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 "Unknown storage system-cause 1" on page 74 below. • The controllers are running a version of XCS that HP Command View EVA does not recognize. See "Unknown storage system-cause 2" on page 74. 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.
