HP rp4440 11i v1 reboot system could not restart

[Gary L]

Hi

Urgent case.

I have a rp4440 box, installed 11i v1 OS. Just now I rebooted system due to there is a mount point has some issue. After boot, system stop at >ISL
error message is:

Boot
:disk(0/1/1/0.1.0.0.0.0.0;0)/stand/vmunix
disk(0/1/1/0.1.0.0.0.0.0;0)/stand/vmunix: cannot open, or not executable

ISL>

I tried to reboot system again and press any key interrupt system boot and goes into the "ISL" mode.
> pa
Primary boot path: 0/1/1/0.1
Alternate boot path: 0/1/1/1.0

Primary boot path boot system failure, so I tried to boot system via alternate boot path
>bo 0/1/1/1.0
y
Booting...
Not a valid boot device (DEV CLASS ERR).
... FAILED.

What the problem is? And how to fix this problem.

Thank you very much. Any answers will be very appreciate!

hi,

first off try to boot the backup kernel, this will at least get you up and running while you fix what you did wrong?

from isl prompt

ISL>hpux /stand/vmunix.prev

see if this boots

or for single user mode

ISL> hpux -is /stand/vmunix.prev

alt boot path only any good if its miirored system, but if you change the kernel on one, you change it on the other aswell with mirrordisk/ux.

Hi ANdy

Thanks for your fast reply.

Just now I have tried boot from .prev, but all didn't work, details are as follows:

ISL> hpux /stand/vmunix.prev
Boot
:disk(0/1/1/0.1.0.0.0.0.0;0)/stand/vmunix.prev
disk(0/1/1/0.1.0.0.0.0.0;0)/stand/vmunix.prev: cannot open, or not executable

both hpux and hpux -is.

What's going on.


Thanks a lotl

See if you can list what's there. There is a "ls" in isl(1m) and another with hpux(1m).
Try: hpux ll

Hi Dennis

Thanks for your suggestion. Below is the result:

ISL>ls

Utilities on this sysem are:

hi,

if you havent got the system back up yet, it los like your only other option will be to run a recovery shell from the core os media and try and rebuild your kernel.

http://docs.hp.com/en/B2355-90772/ch11s13.html

you could just try maintenance mode before, but i think it will be unlikely to boot into that even

ISL> hpux -lm /stand/vmunix

what exactly did you do to the system?

Hi Andy

Thanks for your reply.

For your question: what exactly did you do to the system?

There is a mount point /u01 /dev/vg00/lvol9 in that rp box. The old size is 10GB, I increased the size to 15GB via SAM. But it exit with error. Althrough from SAM Logical Volume it listed the 15GB, but from system # bdf /u01, it still display the old data, and looks like some application software could not access /u01 mount point due to "disk space full etc.". I used # fsck to check and repaire that file system, but it still doen't work, So, I reboot the server via command "reboot". and system could not boot up due to above error.

I will try your suggestion "recovery shell from the core os media and try and rebuild your kernel". see if it works.

Thanks.

Hi Andy

I met a problem when I tried to recovery the bootlif/os partitions, details are as follows:

insert Core OS CD-1
boot from media via >sea p0-media >bo p0
Run a Recovery Shell
Enter: n not start up network at this time.
r - recover an unbootable HP-UX system
b - recover the bootlif/os partitions

The system defualt value are:
Devie file used for "/" (ROOT) is c2t1d0
address: 0/1/1/0.1.0

when I select "a" for the above info is correct, error messages as below:

****Installing bootlif********
-W requires file system on device /dev/rdsk/c2t1d0
\mkboot failed

mkboot failed to update the bootlif!
You will be returned to the "HP-UX Recovery MENU"

When I repeat
r - recover an unbootable HP-UX system
b - recover the bootlif/os partitions
I click "b" WRONG!! The device file used for "/" (ROOT) is incorrect. not "a".
at the prompt line i run command "list", I found there are two local hard disks in that system:
0/1/1/0.0.0 c2t0d0
0/1/1/0.1.0 c2t1d0
so I changed the device and address to "0/1/1/0.0.0 c2t0d0" but when "installing bootlif" the system said::
there appear to be non-boot logical volumes on the device. Overwriting them could destroy all the data on thsi device. SHould the logical volumes be overwritten [y/n], I fear remove important data, so I click "n". error message like above.

How to fix it. And to know which device and address are for boot. from system main menu through command >pa the list path are:
pri - 0/1/1/0.1
alt - 0/1/1/1.0

Thanks

hi,

I think you were on the boot disk first attempt as per your previuos answers

Boot
:disk(0/1/1/0.1.0.0.0.0.0;0)/stand/vmunix

to find all bootable devices on the system from pdc

do a search for ipl

MA> sea ipl

this will list any potential boot devices.

How mayny disks are in the system or attached?

if just the two then it looks like one is a boot disk and the other is a Data disk

Also check what the paths are at pdc and see if they match the disks! your alt path could be the cd/dvd.

MA>pa

then boot the core os cd and follow the instructions in the link provided earlier starting with

Installing Critical Root Files Only

Hi Andy

Thank you very much for your detail suggestions above.

I have worked with HP software support guys from 8:30a.m. to 3:30 p.m. we tried hundreds way to rescue it but all failed.

>SEA IPL just output a DVD media. There are no bootable devices were detected by system, I have no idea what's happend.

>pa list pri and alt path but >bo pri and bo alt all didn't work.

we could mount /root, but could not mount /stand, from Core OS CD-1 we could not do anything include: reover bootlif, kernle ...

They gave me two options:
1. cold OS re-installation.
2. boot system again from Ignite-UX OS image tape, recovery all vg00. But that sever's Ignite-UX tape I made a year ago, sigh.

HP recommend do Ignite-UX image backup weekly and vg00 just for pure OS, other applcaiotns, DBs, data using another Voulem group except vg00.

Anyway, thanks again.

It's not a good weekend.
