I have recently retrieved dump/restore from ftp.brl.mil, & I have been trying to test it out. When I issue the following command, I get the following results: % dump 0usdf 2300 6250 /dev/rmt/xmt0d0.6250 /dev/dsk/dks0d1s0 /etc/dumpdates: No such file or directory DUMP: Date of this level 0 dump: Mon Mar 11 09:38:46 1991 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/dsk/dks0d1s0 (/) to /dev/rmt/xmt0d0.6250 /dev/dsk/dks0d1s0: Permission denied DUMP: Cannot open/stat /dev/dsk/dks0d1s0 If I run the above command as root I get the following response: % /usr1/people/c60244/dump-restore # ~/bin/dump 0usdf 2300 6250 /dev/rmt/xmt0d0.6250 /dev/dsk/dks0d1s0 /etc/dumpdates: No such file or directory DUMP: Date of this level 0 dump: Mon Mar 11 09:39:48 1991 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/dsk/dks0d1s0 (/) to /dev/rmt/xmt0d0.6250 DUMP: Cannot find character device for /dev/dsk/dks0d1s0 Any clues/hints will be appreciated on how to use dump/restore. vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv | Kenneth M.

It might also work to specify the character device (/dev/rdsk/dks0d1s0) instead of the block device (/dev/dsk/dks0d1s0), though I'm not sure about that.. -Stan

@aedc-vax.af.mil:c60244@ccfiris.aedc Kenny - I believe that you are having two separate difficulties with dump/restore. I have directed my response to the whole list, in case others encounter similar difficulties. 1) You need to manually create the file /etc/dumpdates before dump/restore can use it in processing the "u" option, etc. This can be done quite simply by running (as root) this command: touch /etc/dumpdates 2) Your /etc/fstab entries need to include a "raw=" option in them. For example, here are a few sample entries for one of our machines: /dev/root / efs rw,raw=/dev/rroot 1 0 /dev/usr /usr efs rw,raw=/dev/rusr 1 0 /dev/dsk/lv0 /vld efs rw,raw=/dev/rdsk/lv0,grpid 1 0 /dev/dsk/xyl0d1s7 /a efs rw,raw=/dev/rdsk/xyl0d1s7,grpid 1 0 The existance of the "grpid" option is unrelated to dump/restore. Also note that the penultimate column must contain a "1" in order for this filesystem to be eligible for dumping. Best, -Mike

Any clues/hints will be appreciated on how to use dump/restore.
