Replaced a disk, broke boot up

I recently installed HPUX v3 on an rx2620.
there were two disks on the system, and it installed onto the second disk.
Yesterday as i was trying to add the first disk to the VG, it came back telling me i had block errors.

HP replaced the disk today, which i put in. I decided to reboot the system so i could work from a fresh start. On reboot, When it should autoboot HPUX, instead it drops to a Shell> prompt

I dont know a whole lot about the EFI shell so i took out the disk0 again, and still no joy. I had taken out the disk prior to recieving the new one, and everything was working fine, everything was available on the system.

In the boot menu, I have :
HP-UX Primary Boot: 0/1/1/0.0x1.0x0

How do i point this at the disk1 to boot?

this is kind of urgent, so any help will be greatly appreciated.

Re: Replaced a disk, broke boot up

I think you need to look at this document. It pretty much tells you how to change the boot order along with other things about EFI. Good reference in my opinion.

Device mapping table
blk0 : Acpi(HWP0002,0)/Pci(2|0)/Ata(Primary,Master)
blk1 : Acpi(HWP0002,100)/Pci(1|0)/Scsi(Pun1,Lun0)
Shell:\>blk1:
blk1:\> ls
ls: Cannot open current directory - No mapping
Exit status code: No mapping

Should there be "/HD" information at the end of the device mapping for the disk?

(document is very helpful too, thanks)

That doc is all about while the system is live. I dont have access to those commands from the EFI shell

Looks like the mapping cant see any filesystems. Is there any way around this or do i have to go and reinstall from scratch?

Re: Replaced a disk, broke boot up

guess Im going to have to rebuild the OS i reckon. Is there any way to get the information from the disk that is no longer booting? Is there documentation for getting at this LVM?

I need to get this machine back running by the morning, but just being able to get config files etc would greatly reduce the amount of time required on a rebuild.

Re: Replaced a disk, broke boot up

Yep. I removed the failed disk before the replacement arrived, and everything was still running smootly.

So doeas anyone have any suggestions on how to get at the disk contents? I have reinstalled HPUX 11i V3 and just need some config files and such.

I also have a spare rx2620 that i could put the disk into if someone has suggestions on how to make it bootable again.
