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" (page 57) below. • The controllers are running a version of XCS that HP Command View EVA does not recognize. See "Unknown storage system-cause 2" (page 57). 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 6.240. See the "HP Command View EVA interoperability support" table in the HP 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 "Reference documentation" (page 7) for the link to this document. No storage systems found Symptom HP Command View EVA does not display any storage systems, even though they are on the fabric. Cause of the error Several conditions can cause this symptom. Table 8 (page 57) lists some possible causes of these errors and their corrective actions. Corrective action Table 8 Possible causes and corrective actions when no storage system found Possible Cause Corrective Action The management server may not be able to communicate with either controller. Check the connection configuration between the management server and the controller pair. The management server must have a communication path to both controllers in case one controller loses communications with the server.
