Kashif,
Do not change the vfstab options to yes. The system/kernel is not ready to
mount them
at boot.
Your file system vfstab entries should look like this:
/dev/dsk/c0t3d0s0 /dev/rdsk/c0t3d0s0 / ufs 1 no -
/dev/dsk/c0t3d0s6 /dev/rdsk/c0t3d0s6 /usr ufs 2 no -
/dev/dsk/c0t3d0s7 /dev/rdsk/c0t3d0s7 /opt ufs 3 yes -
/dev/dsk/c0t3d0s1 - - swap - no -
You have already confirmed the system hard drive target as "c0t3d0" in a
previous email.
If your vfstab file system entries entries look like the above example I would
try the following.
I am speculating that this WP51 is not the original workstation that the backup
tape
was made from and the hardware complement is different.
1. Boot off the DAY0 CDROM.
ok> boot cdrom
2. Mount the root file system.
# mount /dev/dsk/c0t3d0s0 /mnt
3. Initialize the "/etc/path_to_inst" file.
# cp /tmp/root/etc/path_to_inst /mnt/etc
4. Recreate the "/dev" devices tree for this workstation.
# cd /mnt
# rm /mnt/dev/dsk/*
# rm /mnt/dev/rdsk/*
# drvconfig -r /mnt -p /tmp/root/etc/path_to_inst
# disks -r /mnt
5. Un-mount the root file system and perform a reconfigure reboot.
Make sure you get al clean file system check. (As seen in your previous
email).
# cd /cdrom
# sync /mnt
# umount /mnt
# fsck /dev/rdsk/c0t3d0s0
# reboot -- -r

I changed the CDROM media and the booted from a new version 4.3 DAY 0 CDROM.
When I tried mount, it worked. I listed /etc/vfstab file. It goes like this
both / and /usr ' mount at boot option given as no. Should I change to yes and
try rebooting.

-------------------------------------> Kashif,It is difficult to try and
diagnose this tye of problem remotely.When booted from CDROM I would try to
verify I have a valid formattedsystem hard drive installed in the workstaiton.
For example:1. Run the "format" command and verify valid hard disk/target
install like "c0t3d0".(Use CNTRL-D to exit without making changes to the
drive)2. If your uncomfortable running the format command try and verify the
disktry using the "prtvtoc" command, for example:# prtvtoc
/dev/rdsk/c0t3d0s0The output should reflect the partitioning as described in
the B0193ND.3. If the format appears correct perform an "fsck" on "usr"
partition.# fsck /dev/rdsk/c0t6d0s
64. Have you try mounting one of the other partitions like root or opt?Root is
slice 0, opt slice
