Format=Old_File
    Format=New_Tape

    Specifies whether the backup or optimized .aij file was written
    in the old (disk-optimized) or the new (tape-optimized) format.
    If you enter the RMU Dump After_Journal command without the
    Format qualifier, the default is the Format=Old_Tape qualifier.
    You must specify the same Format qualifier as was used with the
    RMU Backup After_Journal command or the RMU Optimize After_
    Journal command. If your .aij file resides on disk, you should
    use the Format=Old_File qualifier.

    If you specified the Format=Old_File qualifier when you optimized
    or backed up the .aij file to tape, you must mount the backup
    media by using the DCL MOUNT command before you issue the RMU
    Dump After_Journal command. Because the RMU Dump After_Journal
    command uses RMS to read the tape, the tape must be mounted as
    an OpenVMS volume (that is, do not specify the /FOREIGN qualifier
    with the MOUNT command).

    If you specify the Format=New_Tape qualifier, you must mount the
    backup media by using the DCL MOUNT /FOREIGN command before you
    issue the RMU Dump After_Journal command.

    Similarly, if you specify OpenVMS access (you do not specify
    the /FOREIGN qualifier on the DCL MOUNT command) although your
    .aij backup was created using the Format=New_Tape qualifier, you
    receive an RMU-F-MOUNTFOR error.

    The following tape qualifiers have meaning only when used in
    conjunction with the Format=New_Tape qualifier:
