mkvgback command not backing up the files

Env: 
   AIX 325
   RISC 590
   Sysback 3.1.0.34

Desc:  The customer is running the
       mkvgback -vf /dev/rmt0 datavg from the commandline
       and it is not backing up the files in the datavg volume
       group.  

Action:
       1.  lsvg -l datavg
           LV NAME           TYPE           MOUNTPOINT
           oraclelv           jfs            /oraclefs
           loglv00            jfslog         N/A

       2.  tctl -f /dev/rmt0 rewind
           sbread -L /dev/rmt0
           ./.databaseVg.date
           ./oracleFS

  
       3.   find ./oracleFS | -xdev -print
            It returned back nothing

       4.   df showed the filesystem mounted on /usr1
            look in /etc/filesystem showed its real mount on
            /oracleFS

            The customer wanted it mount on /usr1
            So we changed the filesystem stanza in /etc/filesystems
            to match this.  That fixed the problem.

           sysback uses the filesystem stanza to determine the mount
           point of the filesystem.  If the customer from some reason
           changes the mount point in this manner:
           umount /oracleFS
           mount /dev/orcaleLV /usr1
           sysback will then think the mount point is /oracleFS and
           not /usr1 where it is currently mounted.
           sysback bug???  NO it is not a sysback bug!!!

         When the system reboots it will mount it back to /oracleFS
         So checking df to find the mount point would be dangerous
         problem with sysback.  So there will be no change to code in
         this case.
