So a bit of additional 'lore' which is probably obvious to a zillion VMS
admins but was news to me. One can create a standalone backup tape that is
both bootable into standalone backup, and has the system image on it. I did
it as follows:
1) INIT the tape with label SYSTEM
2) @SYS$SYSTEM:STABACKIT
Select MUA0 as the device
Tell it _not_ to re-initialize.
3) Now boot this tape and at the prompt use
BACKUP/IMAGE/VERIFY DUA0: MUA0:MYBACKUP.B/SAVE/LABEL=SYSTEM
Now go away for a while :-)
Once its done you can boot the tape and restore with
BACKUP/IMAGE/VERIFY MUA0:MYBACKUP.B/SAVE/LABEL=SYSTEM DUA0:
This saves me from having to change tapes in the process.
On an unrelated note, I've got a Dataram MS650 board (MicroVAX III memory)
and when it is installed it takes a _longish_ time to past the
initialzation tests and standalone backup appears to hang when run. Has
anyone seen this? Is this perhaps a bad memory chip that is being
constantly repaired by the ECC logic...
