mirroring boot disk in HP-UX 9.04

Hunan_1 — Mon, 05 Aug 2002 20:42:52 GMT

Hi all.
I have some old servers (E25 and E35)running 9.04
Can anyone tell me how to make a mirrored boot disk for this version?
First of all, The servers have two different disks. I have a full backup for everyone of them.

What I want to do is the following:

1.- Make a mirrored disk.
2.- Use one of the disk as backup in case of a disk failure in one of the servers.

To make that I need to make the mirror two times because the disk I wanna use as backup has a SCSI interface which is the same to the boot disk and fits using an adapter.

Any help would be really appreciated.

what are you using for your filesystems? HFS or LVM ?

What was the last patch set that was applied?

Is 10.20 an option?

Disk Mirroring has always been an optional (priced) product so without this software, you can't mirror the disks except by dd'ing them, and even then, you must change the disk's address to match the original disk before it will boot and run correctly.

If you want to create a boot disk identical to the current boot disk you can use dd for that.
The only thing is that the update which is done on the boot disk will not be updated(mirroring).
You can use dd to take a backup of your root disk upto today's date.

Also I checked a link for to do a make_recovery on 9.04

Thanks to every one for your helping...

I don't really want to make a mirror, I just want to have a disk from where to boot in case of some disk failure.

Besides I think Mirror is supported in 9.04 (because It has mkboot and the commands involved ), I have information about that but is for 10.20 and last versions of HP-UX.

Answering to Harry,
filesystems are using LVM
the last patch applied is PHKL_12056
and 10.20 is not an option in this moment.
