• cimom.cxws.agency.timeout - The timeout property controls the allowable interval of
silence before either the CIM Extension or the management server start to question whether
its partner is still alive. If an entity (management server or extension) has not received a
message from the other during the interval set by the timeout property, it will send an “are
you there” message. If that message is not acknowledged during the interval set by the
timeout property, the entity will conclude that the connection is no longer functioning. The
CIM Extension will stop attempting to make a connection. When this occurs on the side of
the management server, the management server will attempt to re-connect (and it will keep
re-attempting until the host becomes available). The default value is 1,000 ms. You are
modifying it to wait 20,000 ms or 3.33 minutes.
3. Click Save.
4. Restart the service for the management server for your changes to take effect.
While AppStorManager is restarting, users are not able to access the management server. The
AppStorManager service must be running for the management server to monitor elements.

Cannot Access a Resource Owned by Another Controller
You received the message about not being able to access a resource owned by another controller
because you tried to access a controller that has not been discovered. You should discover all
controllers on the Engenio storage system.
For example, assume you discovered only one of the controllers on an Engenio storage system with
two controllers. If you want to change a volume, such as add or delete a LUN, you will not be able
to make the change to the volume associated with the controller that has not been discovered.
See ”Discovering NAS Devices, Tape Libraries, Switches and Storage Systems” on page 29 for
more information on how to discover a controller.
Error -56
If you see error -56, the switch has network connection failures/problems. To solve the
problem, make sure the switch is physically connected to the network. Then, redo the task you were
originally trying to complete.
If you now see -21(OBJECT_NOT_FOUND) errors, the switch needs to be rediscovered.
