Hi there,

I've got a ds10 box running tru64 4.0f. I've now also got another
identical box which I've configured the same as the original box and
restored a tape backup. The problem is, it just won't boot.

The machines both have two 8GB drives set as JBOD. (nothing special).
They both have an advfs root/usr/var file system.

I've tried fixing the boot sector with disklabel (although I think its
ok) and I've also tried copying over osf_boot from the original machine.
I'm fresh out of ideas.

Here is some text from the boot.

(boot dra0.0.0.17.0 -flags A)
block 0 of dra0.0.0.17.0 is a valid boot block
reading 13 blocks from dra0.0.0.17.0
bootstrap code read in
base = 200000, image_start = 0, image bytes = 1a00(6656)
initializing HWRPB at 2000
initializing page table at ff2e000
initializing machine state
setting affinity to the primary CPU
jumping to bootstrap code
can't open osf_boot

halted CPU 0

halt code = 5
HALT instruction executed
PC = 20000030[vbcol=seagreen]

Any ideas?

Regards,

Jonathan

You are using ADVFS root. When you restore from tape backup, you do not
restore boot sector (which is advfs). You have to create it using
disklabel.
You can also use one little trick:
1. Boot the "working system" and attach "nonbootable disk" as additional
disk
2. Open graphycal disk configurator and select "nonbootable disk" for
configuring
3. Find the field "boot block" which is usually set to none
4. Change this field to ADVFS
ADVFS boot block is now created and disk is bootable

Thats not an option right now however I will bear it in mind, thanks.

Besides, I think I did this when I did:

disklabel -r /dev/rre0a > /tmp/label
disklavel -rt advfs /dev/rre0a /tmp/label

And it didn't work.

Jonathan

I think you had simply deleted /osf_boot. Copy one from a similar system.
