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.

How do I set the map layout so it stays after Fabric Manager restarted?

If you have arranged the map to your liking and would like to "freeze" the map so that the objects stay
as they are even after you stop Fabric Manager and restart it again, follow these steps:
Step 1 Right-click in a blank space in the map. You see a menu.
Step 2 Select Layout > Fix All Nodes from the menu.
What do I do when two switches show on the map, but there is only one
switch?
If two switches show on your map, but you only have one switch, it may be that you have two switches
in a non-contiguous VSAN that have the same Domain ID. Fabric Manager uses <vsanId><domainId>
to look up a switch, and this can cause the fabric discovery to assign links incorrectly between these
errant switches.
The workaround is to verify that all switches use unique domain IDs within the same VSAN in a
physically connected fabric. (The fabric configuration checker will do this task.)

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
