How do I find out which disk the server booted from

[njia_1]

Hi

I know someone asked this before but I just could not find that question.

I need to find out which disk the server booted from when 2 disks are mirrored.

I tried setboot -v and lvlnboot -v but the problem is that I can not assume the server booted from the primary path. I have to be sure.

thanks

Bonjour,

You can find some informations in result of command "dmesg". For example :

Boot device's HP-UX HW path is: 0/4/1/0.0.0.0.0

from the syslog file:

vmunix: Boot device's HP-UX HW path is: 0/1/1/0.0.0

Hi:

You can also do:

# echo 'boot_string/S' | adb -o /stand/vmunix /dev/mem

Drop the '-o' if you are running releases prior to 11.23.

Hello,

Others already replied with good information.

This test is one of many in my OAT script:

http://www.circlingcycle.com.au/Unix-sources/HP-UX-check-OAT.pl.txt

a) Here is how the results look like for Itanium server rx2620 running HP-UX 11.23:

CHECKING CURRENT BOOT DEVICE
____________________________
0x1f021002

INFO Boot string 1f021002 translates to disk c2t1d0

(;)/stand/vmunix

b) Here is how it looks like on SuperDome nPar (SD32000) running HP-UX 11.11:

CHECKING CURRENT BOOT DEVICE
____________________________
1F008000

INFO Boot device 1F008000 translates to disk c0t8d0

INFO Boot string
boot_string: (4/0/1/0/0/4/0.8.0.0.0.0.0;)/stand/vmunix

c) Here is how it looks like on Itanium server rx2620 running HP-UX 11.31 (Agile view):

CHECKING CURRENT BOOT DEVICE
____________________________
0x3000006

INFO Boot string 000006 translates to disk brw-r----- 1 bin sys 3 0x000006 Apr 1 12:31 disk6_p2

(;)/stand/vmunix

Check my script for details how to obtain
the results...

Cheers,

HI all

Thanks for your replies, as I said setboot and lvlnboot does not help because even it tells me which one is primary and alt, I can't just assume the server is booted from the primary path.

check syslog or demsg may give me the info I want but I will try and will also assign points after.

thank you all
regards

Hi (again):

> check syslog or demsg may give me the info I want but I will try

Have you tried the 'adb' command I suggested? I think that you will find that that satisfies your request.

Regards!
