9245xb VFS_MOUNTROOT failed

[Tanja_4]

Hi,
two days ago our old Hp 9000 D270 stop working.
Now when I turn on the server I get this messages:

Open failed on device 0x1f005000 (0x10)
...
9245xb Pdt
VFS_MOUNTROOT failed

Cannot find ENTRY_TEST
Cannot find ENTRY_INIT
Status= .7

Cannot open LVM BOOT

Primary boot 8/12.5

What's the matter ?
Is it a hard disk failure ? Is there any diagnostic disk I can use to be sure of that ?
Or simply it's the operating system that's corrupted ? And so, I can recover it ?
I think I've not the original installation media. The Hp9000 has two 4.3 scsi hard disks.
Tell me if you need more information.
Thanks a lot,
Tanja

It would appear that thre is some corruption of the boot disk.

Recovery methods:

boot off a recent make_tape_recovery backup after replacing the bad disk, if its bad.

boot off the alternate disk if you set up a mirror disk.

replace the bad disk and reinstall the operating system.

ENTRY_INIT Status = -7

this means that the boot device does not exist, the address specified exists but is not installed or not responding.

can you boot in single-user mode?
You can check for OS crash or disk failure.
To get to ISL on the S800, press any key before 10 seconds have expired (as it says on the screen). Interact with the IPL. Then type `hpux -is'.

It sounds like a hardware failure, but since you can't boot anything, there are no logs. All of the suggestions for recovery (Mirrored disks, Ignite/UX backup, full tape backups) assume that you set up all this prior to the failure. If the system won't boot, you'll probably have to reinstall.

Hi
pulling the disk tray and reseating the disk connectors works.If still persit you may have a bad disk. Check for the disk led again.
Wonder that how many root disk do you have and what about the mirror disk? As you say you just have only primary boot, what about alternate boot path?
That case means all the boot path no respond during booting process.
You don't have the original installation media? You can recover the OS with backup tape (make_tape_recovery or make_recovery)

Thanks a lot.
I will try everything you suggest.
But how can I be sure to have an hard drive hardware failure ? Is there any utility ?
I have also an indication of secondary boot like 8/10.5 . What does that mean ? Having two disk, where I can see if I have a mirror disk ? I try to boot with only one disk, but without the upper the system told me that no boot source found, without the lower I got an error.

This is a problem with your boot disk. You can't run anything when you can't boot up. If you have your original Core/Install CD, you may be able to boot from the CD and run the offline diagnostics or use copyutil as a quick check. However, even if the disk is good, the boot code on the disk has been trashed, so in either case, you still have to reinstall from backup tapes.

> I have also an indication of secondary boot like 8/10.5 . What does that mean ?

HP 9000 processor ROMs have two possible boot paths, but the secondary boot path might point to a data disk, a tape drive, a CD or perhaps to a non-existent device. This path is menaingful only if you explicitly set it prior to your failure and there is a bootable image on the secondary path.

> Having two disk, where I can see if I have a mirror disk ?

MirrorDisk/UX is a priced product that requires a codeword to install, then specific steps to sync the disks. If none of this was done, then you don't have mirroring. The processor ROMs cannot tell you about mirroring.

If you tried to boot from the second disk (you need to know the hardware path to the second disk, then watch it to see if the light on the disk flashes during bootup) and got an error, then that is your answer--no mirroring and no alternate bootable disk.

As mentioned, diagnostics won't help much except to tell you whether you need to replace the disk. In either case, the disk must be reloaded and this requires that you have some bootable media (CD, tape). In the case of tape, you must have traken explicit steps to create this bootable tape, for HP-UX version 10.00 and later, the Ignite/UX programs.
