To access or view the data stored in a UDFS, you must mount the UDFS after every IPL.
When you mount a UDFS, it covers up any file systems, directories, or objects that exist beneath the mount point in the folder hierarchy. This makes those file systems, directories, or objects inaccessible until you unmount the UDFS. To ensure that access to all data in the integrated file system is maintained, mount the UDFS over an empty folder. After the UDFS is mounted, the files within the UDFS will be accessible from within that folder. Any changes made in the folder will be changes to the UDFS, rather than to the covered up folder.
To mount a user-defined file system (UDFS), follow these steps:
If you like to drag and drop, you can mount a UDFS by dragging it to a folder within the integrated file system on the same server. You cannot drop the UDFS on /dev, /dev/QASPxx, /dev/asp_name, another system, or the desktop.
