Hi,
I want to move the root_domain (on a 4100 5.1A PK2) to a different device so
I followed the instructions in 5.3.3 and 5.3.4 in the AdvFS Administration
guide:
http://www.tru64unix.compaq.com/docs/base_doc/DOCUMENTATION/V51A_HTML/ARH96C
TE/TOC.HTM#CHPTRTRB
and now when the machine starts to boot it gets a cpu exception at (I think)
'cant open osf boot'.
Here's what I did:
used diskconfig to partition an RZ29B (AdvFS on partition a)
backup / (root) and /usr
boot from CD
mkfdmn -r /dev/disk/dsk3a root_domain
mkfset root_domain root
mount root_domain#root /mnt
mkdir /etc/fdmns/TMP_BACKUP
nkdir /var/tmp_backup
mkfset TMP_BACKUP tmp_backup
mount TMP_BACKUP#tmp_backup /var/tmp_backup
cd /var/tmp_backup
tar -xv #get backup off tape
vrestore -x -f thor.51A.PK2.root.vdump -D /mnt #restore root_domain to new
device
cd /mnt/etc/fdmns/root_domain
ln -s /dev/disk/dsk3a dsk3a
rm -e dsk4a # previous root partition
shutdown -h now
set bootdef_dev dkb400
boot
it gets to 'jumping to bootstrap code' then produces the 'cant open osf
boot' error.
Anybody have any idea what I've done wrong? What if I, in the first 2 steps
above, I did a backup (vdump) first then ran diskconfig for dsk3 -- would
the vrestore overwrite what the diskconfig had done? Should I disklabel
dsk3 again?
Thanks!
Andy
