Scenario 2: Cannot mount, unmount, or access a "mounted" file system

The file system does not appear to exist in the shared file system. Any attempt to mount the file system, however, fails with EINVAL (X'79'), JrIsMounted (X'055B005B'), and any attempt to unmount the file system fails with EINVAL (X'79'), JrFilesysNotThere (X'0588002E').
