Xsan: Finder may not immediately display directory contents when accessing StorNext 4.x volumes

Directories on a StorNext 4.x volume may appear to have no contents when viewed in the Finder from an Xsan client that is using OS X Lion or Mountain Lion. The contents eventually appear, and they appear immediately when using the ls command in Terminal.

Enable fast reverse path lookup (RPL) on StorNext 4.x volumes that will be accessed by Xsan clients running OS X Lion or Mountain Lion.
