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 6.220.

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

Cause of the error

Several conditions can cause this symptom. Table 8 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

Corrective ActionPossible Cause

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.

The management server may not be able to

communicate with either controller.

Enter the correct password through HP Command View EVA or disable

the password on the controller.

When HP Command View EVA is first starting

up, a password may be enabled on the con-

trollers, but a password has not been entered

in HP Command View EVA.

Verify that switches are zoned correctly.

The switches may not be correctly zoned,

making a storage system invisible to HP

Command View EVA.

1. Verify that the controllers are up and functioning properly.

2. Check the cable connections between the management server and

the switch.

3. Verify that switch zoning is correct.

4. Click Discover.

HP Command View EVA may have been re-

started while there was a communication

failure between HP Command View EVA and

the controllers. When restart is completed,

the storage system that lost communication

will not be visible.
