HP StorageWorks Enterprise Virtual Array Updating Product Software Guide (XCS 09534000) (5697-0754, October 2010)

Corrective ActionPossible Cause
Reinstall HP Command View EVA.
404 Error: A .frm (HTML) file may be missing in the HP
Command View EVA directory structure. This can occur
if the files were changed or if HP Command View EVA
was not successfully installed.
Retry the request when HP Command View
EVA is up.
503 Error: HP Command View EVA may be down when
a browser makes a request. The web server returns a 503
(No Service) error because it cannot access the page.
Retry the request when the appliance and HP
Command View EVA are up.
Browser timeout: The appliance may be down or the web
server may be unavailable when a browser makes a re-
quest to HP Command View EVA. In this case, the browser
will time out internally.
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 75 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 75.
Unknown storage system—cause 1
When the array 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
09534000. 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. Then, upgrade HP Command View EVA to a compatible version. See
“Required documentation” on page 10 for the link to this document.
