HP-UX 11.00 Mirror boot disk for new Server

[Cory Gaetz(1)]

Hello folks,

I have to build a new rp5470 (PA-RISC) that needs to be identical to an existing rp5470 running HP-UX 11.00. For various business related reasons Ignite-UX is out of the question.

We have decided that the best method then is to take the OS down, pull out one of the existing mirrored disks, put a new disk in it's place, and create a new mirror on that for use in the new box. I have done this before, but only on newer boxes with a newer OS.

Any help on an exact procedure on how to do this would be greatly appreciated. 10 pts to anyone that can help. Thanks.

Cory,

If all cards, and all things are in the same place as the main server - just use "dd" and make a copy of that disk on tape.

$> dd if=/dev/rdsk/xxxxx of=/dev/rmt/0m bs=32k

do a tape for both the main and the mirror disk.

Then, take one of the drives and put in the scsi chain, and dd back to it. You can use any server which yields relatively easy access to the scsi chain.

$> dd if=/dev/rmt/0m of=/dev/rdsk/xxxxxx bs=32k

repeat for other disk.

Remembering which is the primary and which is the alternate, put them in the other server and boot up.

You can use most any Unix computer for this, even a PC box running Linux.

Thanks for the quick response Two_Proc, unfortunately I don't have access to a tape drive either for this change. I'm really hamstringed by having to do a disk to disk copy.
