Creating a mirrored boot disk under HP-UX v11.22 and cloning

[Mark Everett]

Two issues:
1) looking for a detailed procedure for creating a mirrored boot disk under HP-UX v11.22
2) Cloning the system disk to other identical systems

I am setting up four identical IPF-based 5670's with HP-UX v11.22. My plan is to complete the install and configuration on the first system, then create the other three through cloning the first. I want to mirror the system disk on each and have installed MirrorDisk/UX.

It seems like I could use MirrorDisk/UX to create these clones, and force set_parms to trigger on boot for each clone.

Does this sound like an effective plan? Or, is make_tape_recovery a better route?

Has the procedure for mirroring the boot/system disk changed much since 11.22 came out? (I have HP's DocID #LVMKBRC00005103 dated 4/20/01)

Thanks,

-Mark

Hi Mark:

The creation of a bootable mirrored vg00 should be unchanged.

I'd use Ignite's 'make_tape_recovery' to create an image of the first system's vg00 and then use it to clone (cold-install) the remaining three servers.

Of course, Ingite doesn't mirror, so you will have to repeat the mirror setup on each server thereafter, but that's not any big issue in my opinion.

Regards!

Ignite will mirror if you use a post configuration script. This can be done when cloning a system that already has mirror/ux installed with appropriate codewords.

I've done it with a Golden Image transfer.

Attaching the config script.

Thanks for the suggestions folks.

I'll make an attempt to use Ignite.

One related concern I have regarding mirroring involves the form of the disk device. I noticed that my 'master' install ended up with a physical volume name of /dev/dsk/c0t2d0s2 for vg00. I've never noticed a specific slice number beging assigned before. My HP-UX v11.11 systems (on PA-RISC) do not include a specific slice, only showing the entire disk (eg /dev/dsk/c1t0d0).

Perhaps this is a function of incorporating more Veritas into HP's LVM (which I used to create the volumes and filesystems)?
