When the main directory is destroyed, for instance in connection with a physical disk crash, SINTRAN and the Backup System are not running. In tjhis case, you can use the stand-alone program DISK-RESTORE to restore the main directory.

NOTE: Only backups take with the Backup System command DEVICE-COPY can be restored with DISK-RESTORE.

The DISK-RESTORE program is delivered on three floppy diskettes, 211187A<rev>-XX-01D, 211187A<rev>-XX-02D and 211187A<rev>-XX-03D.

Note that the program must be run from TERMINAL-1 (the console).

  • insert 211187A<rev>-XX-01D in floppy diskette unit FLOPPY-DISC-1, unit 0.
  • Execute the following commands. Do not press ENTER after 1560&:
  -- FLOppy to MEMory copying --
Insert next floppy and type any character to continue -->
  • Remove 211187A<rev>-XX-01D and replace it with 211187A<rev>-XX-02D. Type any character to continue.
  • You are then asked to insert another floppy diskette. Insert 211187A<rev>-XX-03D and type any character to continue.

If the starting of DISK-RESTORE is successful, you get the following message:

-- End of copy, starting now the SINTRAN
hh.mm.ss mm.dd.yy ERROR 40 IN BAK01 AT 35104; POWER FAIL
  • Press ENTER to get the prompt Di-Re: on the screen. Mount the backup storage medium on the source device, and execute the command RESTORE-DISK:
Destination device name: DISC-70MB-1
Destination device unit: 0
Source      device name: STREAMER-1
Source      device unit: 0

Mount the first backup medium on STREAMER-1 unit 0
Mounted (Yes/No?): YES
