What do I do when SCP/SFTP fails when a file is copied from local machine to
the switch?
If there are embedded spaces in the file path, then windows scp/sftp might fail. You will get a
copyDeviceBusy error from the switch. In tools such as the License Wizard either make sure tftp copy
can be done or pick filenames with no spaces.
UNIX Issues

What do I do when the parent menus disappear?

Displaying a submenu may occasionally cause the parent menu to disappear. For more details on this
bug, refer to: http://developer.java.sun.com/developer/bugParade/bugs/4470374.html.

What do I do when the web browser cannot find web server even it is running?

This can happens when web browser uses proxy server. To check that for Internet Explorer, choose tools
in menu, then choose internet options, then choose connection subpanel, then click Lan Setting. A dialog
comes up, verify the proxy setting.

How do I fix a "too many open files" error?

If you are running the JVM (Java Virtual Machine) on Linux and the drive where Java is installed or your
home directory is NFS mounted, there is an open bug against the Sun JDK about errors acquiring file
locks. The symptoms for the Fabric Manager are that launching a Device Manager or saving/opening
files will fail, giving a "too many open files" I/O or socket exception. The JVM keeps trying to open a
file on the NFS mounted drives, fails, and keeps trying to do it until it hits the 1024 file descriptors limit.
Workarounds (assuming /tmp is a local disk - replace it with your tmp area):

System Preferences
Make sure the system level preferences are stored on a local disk. The system preferences are stored
in $JAVA_HOME/.systemPrefs where JAVA_HOME is where you have installed the JDK. If this
directory is NFS mounted, then just do the following:
$ rm -rf $JAVA_HOME/.systemPrefs<
$ mkdir /tmp/.systemPrefs
$ ln -s /tmp/.systemPrefs $JAVA_HOME/.systemPrefs
The problem with this workaround is that you have to make sure /tmp/.systemPrefs exists on every
box where you are using $JAVA_HOME. We recommend installing the JVM as root and on a local
disk.
User Preferences
If your home directory is NFS mounted and you are getting this problem. Do the following:
$ rm -rf $HOME/.java
$ mkdir /tmp/.java.$USER
$ ln -s /tmp/.java.$USER $HOME/.java
