unable to boot the tru64 unix server from the SRM prompt

[Vladimir Fabecic]

So you have 7 disks connected to "normal" SCSI controller and 2 disk connected to SWXCR.
Now I am a little bit confused.
Please boot from install CD and send output of:
# hwmgr -view device
It is very important to see which disk is mapped as dsk0
I will have not much time today so please hurry.

[Vladimir Fabecic]

And please send output of:
# disklabel -r dsk1

[Vladimir Fabecic]

Looks like your "old root" should be dsk1a not dsk0a. Waiting for your reply.
Procedure:
1.
# cd /etc/fdmns
# mkdir tmproot
# cd tmproot
# ln -s /dev/disk/dsk1a
# cd /
# mount tmproot#root /mnt
Send output of:
# ls -al /mnt
2.
# dn_setup -install_tape
Send output of:
# hwmgr -show scsi
3.
Restoring file system backup tape
(lets say that "old root" is already mounted in /mnt)
# cd /mnt
# vrestore -x -f /dev/ntape/tape0 (or whatever is tape device)

But you must be sure you have the right save set loaded in tape drive.
To check out do:
# vrestore -i -f /dev/ntape/tape0
and do "ls" when get prompt

Hi,

Please fins the output of disklabel -r dsk1

In the previous post VS640 is the tape library.

Hello,

I am getting error when I am trying to mount the disk.

# cd /etc/fdmns
# mkdir tmproot
# cd tmproot
# ln -s /dev/disk/dsk1a
# cd /
# mount tmproot#root /mnt
output:
tmproot#root on /mnt: Device does not contain a valid ADVFS file system.

and

# hwmgr -show scsi

its showing the

Hi,

I've still not seen the output of "show boot*"

However, I'll guess that you should try booting up off dra0.

P00>>> b dra0

Cheers,

Rob

[Vladimir Fabecic]

Rob,
I do not think that machine can be booted from DRA0. See output of "disklabel -r dsk0".
As I can see, dsk0 is DRA0, and dsk1 is DKD0.
DRA0 has just one partition marked as advfs (partition "a"), and DKD0 does not have any partition marked as advfs or ufs, but has primary boot block created.
Default boot device is probably DKD0.
Imran,
Your situation is very strange and confusing.
Looks like someone changed disk label or something like that. That does not look like a hardware problem to me. Also it does not look like file system or domain corruption (it does nor change disk label)
Please do the following before restoring backup:
1.
Boot from Tru64 Unix V5.1B Media and go shell
2.
Do:
# dn_setup -install_tape
3.
Send output of:
# hwmgr -show scsi
# hwmgr -view device
# mt status
# disklabel -r dsk0
# disklabel -r dsk1
# disklabel -r dsk2
# disklabel -r dsk3
# disklabel -r dsk4
# disklabel -r dsk5
# disklabel -r dsk6
# disklabel -r dsk7
