Thanks to all that replied before, I have been able to MOSTLY create a
working backup of my HPUX 8.0 system. Still have a glitch to work out but,
I'm getting a lot closer.
Originally, I was using two different size disks and that wasn't working out
so, now I'm using identical disks for the source and target.
I am using the "dd" command to copy the data from the existing root disk
partitions to the target.
dd if=/dev/dsk/c1000t0d13 of=/dev/dsk/c1008t0d13 bs=1024k
dd if=/dev/dsk/c1000t0d2 of=/dev/dsk/c1008t0d2 bs=1024
Now I can boot hpux on the backup disk but only if I boot ISL on the
original disk. When I load ISL from the original 8.0 disk, it shows a
different version than when I load ISL from the backup disk. The backup disk
was previously loaded with 10.20 and it appears that dd did not overwrite
that portion of the disk.
Unfortunately, the 10.20 version of ISL will not boot the 8.0 version of
HPUX. It reports a funky out of memory error or some such.
I realize in this case that the dd command is only moving the "13" and "2"
partitions of the disk and ISL is probably not on either of those
partitions.
"ioscan -fn -C disk" reports about 50 different special files for each drive
and I really don't to wade through all of them to find the right
combination. I have tried a few of the obvious like "c1000t0d0 --->
c1008t0d0" but still haven't found the right combination to copy the ISL
sectors.
So... the question(s) is:
What partition is ISL on?
Will dd copy ISL or do I have to use a different utility?
Thanks, Steve
