Boot area corrupted after power down C3000 Visualize

Oleg Zieaev_1 — Wed, 28 Jul 2004 09:57:48 GMT

Hi
I recently got C3000 HP workstation and run into problem with missing boot drive if it reboots or has power failure.
Currently using work around and do boot to recovery shell to fix it each time. I do not have that many power failures. But still want to fix it. B180 standing right next to it is booting fine each time, even after power downs.
lvlnboot reports missing boot volume and lif area got 'hpux -lm /dev/dsk/...'. I understand why system boots in LVM maintenace mode. However root cause is still in doubts.
Please advise.

Thanks,

When in lvm maintenance mode, fsck all lvols.
Also, is this boot disk properly fitted into the box. check for loose connections. cables etc.
Which version of OS??

Hi Oleg,

You can try and fix the BRDA if that is what is wrong. you use the lvlnboot command to fix that.

Can you post the output of your "lvlnboot -v /dev/vg00" command.

What is the exact error you get when you boot / reboot the system.

Hope this helps.

Hi.

Boot Definitions for Volume Group /dev/vg00:

Boot: lvol1 is missing after I boot to recovery shell.
It also tells me to redefine root,dump and swap areas after I use option "b" in "recover unbootable hard drive" menu.

Is it booting into single user mode?? If yes, run mkboot -a "hpux -lq" /dev/rdsk/cxtxdx

Booted to single user mode.
Run all commands.

Should I reboot or reboot -n?

Re: Boot area corrupted after power down C3000 Visualize

Goto single user mode and post the output of the following command.

lifls -l /dev/rdsk/cxtxdx

AUTO area is empty.
lifcp gives io error when I try to list the content:
lifcp /dev/rdsk/c3t5d0:AUTO -

Might this be a HDD problem?

It is doubtful that this is a hard disk problem. You would see error messages like I/O error or errno 5. The lif area is the first filesystem on the disk but someone playing with the lif commands could have removed everything or perhaps just the AUTO file was removed. Just recreate the AUTO file in /tmp, then use lifcp to copy it to a new AUTO file.

This is fresh install (less than 7 days). I am the only user for now on this system.
Also, even after I put "hpux" into it via mkboot -a "hpux" /dev/rdsk/c3t5d0
it is working up to the time of power down.
(shutdonw -h).

tried to copy AUTO file from /tmp.
lifcp gives an error: file already exist

Re: Boot area corrupted after power down C3000 Visualize

Bill Hassell — Wed, 28 Jul 2004 15:31:23 GMT

You'll need to remove the AUTO file (since it exists but has nothing in it (lifrm) and then use lifcp to copy it back.

done.
reboot - works.
power down - failed again.
this time it does not boot to ISL.
has to go to recovery CD.
