Troubleshooting the Java Plug-in

Java Applet Has Data from a Different Build 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 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

• Cannot Access a Resource Owned by Another Controller, page 720
• Error -56, page 720
• “Can't delete this zone” Message, page 721
• Changes in EFC Manager Requiring Discovery Data Collection, page 721
Cannot Access a Resource Owned by Another Controller
If you receive a message about not being able to access a resource owned by another controller, it
is because you tried to access a controller that has not been discovered. You should discover all
controllers on the LSI storage system.
For example, assume you discovered only one of the controllers on an LSI 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.
