HP-UX 11i v1 booting problem

[Mohammad Mostafa]

i tried, it takes a very long time with no response at the end ( i ended the session after about 15 minutes not responding)

[Mohammad Mostafa]

i mean the
# vgchange -a y vg00

it takes long time without any response

[sujit kumar singh]

hi try

#vgchange -a y -q n vg00

perhaps there is a Failure of the disks.

also show
#ioscan -fnCdisk

also do a
#lvdisplay -v /dev/vg00/lvol3

to know the alt boot disk if any.


regards
sujit

Hi Sujit,

The output of the cmds are down, i need to ask you if the following has anything to do with the problem, it is displayed after hpux -lm execution (and before the prompt is reached)

HI


the messsage that you said might be due to the corruption in the LVM information regarding the root boot and wap config, that can possibly be set using the list og lvlnboot command as said earlier,
the other part i would like to suugest is to use

on the BCH Main menu> boot alt

or BCH MAIN MENU>SEarch
Boot using pX for the path


P0 0/0/2/0.0 ide.0 Random access media 0 --- DVD rom

P1 0/1/1/0.1 intscsia.1 Random access media 0 -- primary path

P2 0/1/1/0.0 intscsia.0 Random access media 0 -- can be alternate path

P3 0/1/1/1.2 intscsib.2 Random access media 0 -- can be altrnate path


you can try booting using the Suspected alternate path giving the syntax after the search command
as

boot 0/1/1/0.1
or
boot 0/1/1/1.2

If you have an older record of the VG vg00 like earlier Nickel then that can be helpful

vgchange hangs
This seems to be a serious H/W issue and you might need to replace the disk.

[Avinash20]

You could check if the disk is perfect via booting from the recovery CD and running fsck on the disk. If this hangs then surely H/W needs to be checked.

Hi Sujit and Avinash,
i'm really grateful but i'm also got tired.
i'll continue tomorrow and i'll keep you updated and i hope you will keep following with me.

Thanks a lot

Hi Sujit,
I used # hpux -lm -lq as you said before
and that time when i executed the
# vgchange -a y -q n vg00
it was successful,

while executing the fsck, i got the following
# #########################################

# fsck /dev/vg00/lvol1
fsck: /dev/vg00/lvol1: possible swap device (cannot determine)

continue (y/n)? y

***** MARKING FILE SYSTEM CLEAN *****

***** FILE SYSTEM WAS MODIFIED *****

# #######################################

At the mount step, i got the following

# ########################################

# mount -a
vxfs mount: /dev/vg00/usrvol is corrupted. needs checking
vxfs mount: Cannot open /dev/vg01/lvol2: No such device or address
vxfs mount: Cannot open /dev/vg01/lvol1: No such device or address
# ########################################




Any recommendation?
