Troubleshooting 626
Java Applet Has Data from a Different Version
of Management Server Software
If you attempt to monitor a host with old JAR (Java Archive) files, you might be unable to monitor the
host and you might see the following error message:
The Java applet has data from a different version of the management server.
Please close and re-start your browser.
The reason for this error message is that the client still has JARs from the previous build in its Java
Plug-in cache. To remove the old JARs, clear the cache for the Java plug-in.
OutOfMemoryException Messages
In some rare cases it may be necessary to increase the amount of memory for the Java plug-in on
the client computer. This should only be done if you are seeing OutOfMemoryException
messages in the Java console on the client side.
Improving Reload Performance in System Manager
If your Java plug-in control panel cache setting is set at 50 MB, it is recommended you increase this
setting to 150 MB or more. Increasing this setting improves the reloading performance of System
Manager.
Troubleshooting Provisioning
This section describes the following:
• ” Cannot Access a Resource Owned by Another Controller ” on page 626
• ” Error -56 ” on page 626
• ” “Can't delete this zone” Message ” on page 627
• ” Changes in EFC Manager Requiring Discovery Data Collection/Get Details ” on page 627
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 Filers, Tape Libraries, Switches and Storage Systems ” on page 15 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.
