HP EVA Updating Product Software Guide (xcs10001000) (5697-2423, December 2012)

Cause
HP P6000 Command View may have lost communication with the controllers. Two possible scenarios
follow:
• The management server HBA may have timed out commands to the controllers. See “Unknown
storage system” (page 65).
• The controllers are running a version of XCS that HP P6000 Command View does not
recognize. See “Unknown storage system” (page 65).
Resolution
Unknown storage system – cause 1
If the array has a heavy I/O load, the HBA in the management server may time out commands to
the controllers. If this occurs, the array appears in the Unknown state.
Corrective action
This scenario should correct itself in less than one minute. Alternatively, you can perform a Rediscover
operation to initiate new commands to the controller.
Unknown storage system– cause 2
HP P6000 Command View can only manage controllers that are running supported XCS versions.
Corrective action
Ensure that you are running the HP P6000 Command View version that is compatible with XCS
10001000. See the “HP P6000 Command View interoperability support” table in the HP P6000
Enterprise Virtual Array Compatibility Reference to determine which version of HP P6000 Command
View you should be running. Then, upgrade HP P6000 Command View to a compatible version.

corrective actions.
