On storage servers that have a very large number of file systems available, the UI may time out while refreshing the list of available file systems, resulting in a No File Systems Available message. This usually means that the time out value is set too low for the number of file systems that the UI needs to refresh. To resolve this, change the settings for the Refresh Timeout Value in the Preferences Pane on the Tools and Resources tab in the Oracle VM Manager Web Interface to increase the timeout value.

See Preferences in the Oracle VM Manager User's Guide for more information on Oracle VM Manager UI preferences.
