Troubleshooting the Java Plug-in

• ”OutOfMemoryException Messages” on page 676
• ”Improving Reload Performance in System Manager” on page 676
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 677
• ”Error -56” on page 677
• ”“Can't delete this zone” Message” on page 677
• ”Changes in EFC Manager Requiring Discovery Data Collection/Get Details” on page 677
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.
