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 69 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 70. 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. HP StorageWorks 4x00/6x00/8x00 Enterprise Virtual Array Updating Product Software Guide (XCS 6.220) 69
