When this occurs it is possible to recover your system from the Shell option
from the Utilities menu.
These steps will pick up after fdisk & divvy have been executed.
mount /dev/hd0root /mnt
mount /dev/boot /mnt/stand
This example will assume you have a /u and a /u2 filesystem on the primary or secondary drive that you do not wish to restore.
cd /mnt
/bin/edge -xvbkfEE a b /dev/tape ./u ./u2
NOTE:
a would refer to the block factor of your tape.
b would refer to the volume size of your data cartridge.
/dev/tape would refer to the device name of your tape
drive.
This will restore the root filesystems and exclude the /u & /u2
filesystems.
When the restore is complete, change directory and umount your
mounted filesystems
umount /mnt/stand
umount /mnt
Finally, to be safe and possibly save time later, force a boot
track & master boot record. This too will need to be done from
the shell. Type the following
dparam -w
dd if=/etc/hdboot0 of=/dev/hd0a
dd if=/etc/hdboot1 of=/dev/hd0a bs=1k seek=1
