Mirroring on HPUX

panks — Tue, 21 Oct 2008 15:06:36 GMT

Dear All,

I want to do the mirroring on my RX8640 box having HPUX 11.23 installed. I heard about licensing, do I need to buy a licenese to do even a software mirroring (One disk to other).
Also, please tell me the procedure.
Thanks

you need to buy MirrorDisk/UX, but there are certain Operating Environments that include this product.
The procedure is laid out in:
http://docs.hp.com/en/B2355-90950/B2355-90950.pdf
start at page 634 I think

Thanks for the postings.
I used the link given by Asif, it worked for me.

I just have one issue, when I rebooted the server and tried to boot from the alternate disk, which I have added for RAID I am getting following messages.

Selected boot option: HP-UX HA Alternate Boot: 0/0/0/3/0.6.0

" Is it like unless our pri disk fails we can't check mirroring by booting from other disk"

If 0/0/0/3/0.6.0 is the new drive you just mirrored to your primary and it will not boot then I suspect you did something wrong.

Rip apart and start over. Once done correctly you should be able to boot from the mirror/alternate device.

This obviously is a MUST test scenario, does no good to find out it does not work after your primary fails.

This server is going to be a prodcution server. I mirrored each logical volume individually except swap.

I used the procedure given by asif in the link of forum.

Pls suggest which procedure shall I follow, to setup correctly and how can I remove the configuration I done using the above link.

You should ALWAYS mirror the swap - otherwise the mirror is almost usless!

Stop boot here:

HP-UX Boot Loader for IPF -- Revision 2.029

Press Any Key to interrupt Autoboot

and do

HPUX> ls -l

Procedure is here:
