Corrective Action
Possible 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.

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.
Enter the WWID.
A storage system may not be visible to HP
Command View EVA because the controllers
are waiting for World Wide ID (WWID) to
be entered. This condition will occur if the
storage system has been uninitialized and
the cabinet is power cycled.
This may also occur if backend problems are
preventing access to the quorum drives. Once
communication is restored, the WWID along
with the checksum can be re-entered.
