One of the mirrored disk on the system had failed, so we replaced it physically. For reinstating the data in replaced disk from the original, we followed the steps in the attached file.
We got up to step 9, and we had to reboot the machine to free up the vg00 so that it could be deactivated.
Now the machine won't boot and is stuck on EFI boot menu. I am guessing that it is trying to boot from the newly replaced disk, whose data was not yet fully restored.
Can anyone help us to boot from the original disk? Machine is rx4640, OS is HPUX 11.23. The system is part of an MCSG cluster. Let me know if any other info is needed.
Solved! Go to Solution.

Re: Production server stuck on EFI shell and cannot boot
Do you see any fs entries when you do a "map -r" from EFI, e.g. fs0: ?
Hope this helps!
Regards
Torsten.

This looks like your
/stand
is empty, hence no kernel.
Hope this helps!

Torsten.

Solution"We got up to step 9, and we had to reboot the machine to free up the vg00 so that it could be deactivated." ?
Looks like you don't have any OS data on your disk - the disk is empty. What happens to the other disk or the mirror pair?
There is only 1 disk with an EFI area.
Do you have an ignite backup?
You will probably need it now ...
Hope this helps!
Regards
Torsten.

Re: Production server stuck on EFI shell and cannot boot
Your alternate disk does not have /stand
set up properly.
Just last week I was teaching HP-UX for Experienced Admins in Australia and
one of the students made a mistake to
created a mirror on the second disk but the first slice was not /stand :)
Obviously, it did not work. Luckily,
it was a virtual lab and I helped him.
Than I sat down, and for the sake of my students create a small Shell script to
mirror and/or unmirror LVM boot disks
for HP-UX (it even takes care of
legacy and agile DSF in HP-UX 11.31):
http://www.circlingcycle.com.au/Unix-sources/HP-UX-11x-LVM-mirroring.sh.txt
I am still testing the script...
Maybe similar mistake happened in your case?
Cheers,

Luckily we have ignite backup. We will be restoring from it shortly.

Re: Production server stuck on EFI shell and cannot boot
As per your attached file I can see your EFI partition is only 100MB
If you are useing 11.22 then its ok if you are using 11.23 then your EFI partation should be 500MB
Create a partition description file:
HPUX 100%
# vi /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB
