patch update

Hi,

I need to install the most recent patch on a critical system running 11iv3. I need to have a strong roll back plan. I don't have a disaster system.

I know, I will required a backup and ignite tape. Do you have other idea that can speedup my restore process in case of roll back.

My hardware is rx7640 with 2 internal disk and an eva 4400 running VSEOE.

Thanks,

Re: patch update

Do you have another hp-ux available? If so, you can use it as a ignite server.

Re: patch update

You can try to split the mirror and keep one untouched while the other for patch installation (alt disk). I am not sure whether it is feasible or any document for it. But you can test it in a sandbox first.

Re: patch update

Hi ... after a long time..

As our mate said, if you have spare disk there is no best solution other than DRD ( dynamic root disk).

There is no better roll back plan which is better than DRD , available as of now.

Please post your doubts on DRD now..

Re: patch update

Hi,

What I used to do is boot the server form alternet disk if everyting goes fine then shutdown the box. take out the alternet disk from the server now boot from the primary disk install your critical patch.
if its fail just shutdown the box fix the alternet disk and boot from alternet disk mirror back to primary disk.

Re: patch update

Any ways if you do no have DRD configured, just remove the mirrored disk apply patch if u like OK else put the disk back and boot from it, you back on the last stage.

I suppose Ignite is also pretty fast and good when everything fails it works :)

Re: patch update

For taking the diskout, you should have hardware access ;)

There is nothing to configure for DRD.

Download and install the product. Thats it.use DRD commands to install the patch

Ohh I forgot that with 11.31, DRD will come by default ..( if I am right)

Re: patch update

Hi,

DRD seems to be the way to go, I heard about it with the clone component, but I never used it.

Do you have a quick guide or reference for me. I need to make an update on a major system saturday night.

Thanks,
Torsten.

Re: patch update

All the docs are in hp.com/go/bsc now.

http://www.hp.com/go/drd

Create a clone, patch or upgrade the inactive clone, on downtime just activate the clone and boot. Done.

If everything is fine, ok.

In case of problems, boot the original.

Hope this helps!
Regards
Torsten.
