Boot Disk Failure

ramendra — Fri, 12 Sep 2008 18:53:43 GMT

Hi,
I have recently replaced my primary boot disk and when tried to reboot the server,the following message is appearing...
ISL >hpux -is

Boot
: disk(0/0/1/1.15.0.0.0.0.0;0)/stand/vmunix
disk(0/0/1/1.15.0.0.0.0.0;0)/stand/vmunix: cannot open, or not executable

I also tried the same with my secondary mirrored disk but getting the same error.The System is still at ISL Prompt.

My OS Version is 11.11 and its a PARISC Server.

How to resolve this ???

Thanks

Did you create an ignite image ? If so use that.

I am assuming that

1) you did not recover the failed disk correctly after replacing, e.g. using pvcreate -B, mkboot, etc..

1) I am also assuming on the mirror, that you did not orgionally create that correctly and test.

Supply the process/commands you used to replace and re-sync the OS. You may be able to recover this if you do not have ignite by booting a CD based version of HPUX and using recovery shell. Maybe.

Recovery docs attached.

Kindly suggest.Thanks

Nothing wrong with your doc. Looks good.

So you were able to initially boot the mirror to single user mode to fix the primary. Now you cannot boot either ?

hmmm.....

Either there was an error following your instructions or there were errors that were overlooked while following the instructions.

Where to go from here ? I am on my way out for the weekend so hopefully someone else can chime in to help find a solution.

SOrry.

Hi Ramendra,

Did you do pvchange before removing the disk?
Also your doc does NOT include using commands:

#lvlnboot -r /dev/vg00/lvol3
#lvlnboot -b /dev/vg00/lvol1
#lvlnboot -s /dev/vg00/lvol2
#lvlnboot -d /dev/vg00/lvol2

But this might not provide you the complete solution, i am afraid.
Else, using recovery shell use is the best option..

ramendra, your procedure looks wrong to me ...

Try

ISL> hpux ll

Re: Boot Disk Failure

ramendra — Sat, 13 Sep 2008 18:03:56 GMT

ISL> hpux ll

Ls
: disk(0/0/1/1.15.0.0.0.0.0;0)/.
cannot open directory

ISL>

Can anyone send me the procedure of the recovery shell using HPUX OS CDs...???

Please follow the following steps .
and this will work .

1) Boot off the recovery CD and run Recovery Shell

According to the procedure (your attachment) you did, there is a step

mkboot â l /dev/rdsk/c1t15d0
without a previous "pvcreate"
followed by

vgcfgrestore ...

I think this didn't work.

Can you boot from the other disk?
