HPUX 11.23 root disk replacement with mirror

[Tony Drake_2]

I am working on some documentation for our new Itanium systems. I have the HP document for mirroring a root disk for the first time, which includes creating the efi and SP partitions and so on.

What I cannot seem to find is the corresponding document for replacing the root disk in a mirrored pair.

I know it is slightly different, since the new "raw" disk will not have the partitions, but I would hope that it would not require executing the full first time mirror protocol.

Our current 11.11 and below procedures use vgexport, vgcfgrestore and vgsync to bring on a new mirror.

Can you point me to the HP document, or give me a working procedure to do this? Or do we just use the first time mirror procedure? It is taken from DOC ID: KBRC00014526

Thanks.

This is the document that I already have.

What I am looking for is the document that tells how to replace a root disk, not one that shows how to mirror for the first time.

Have a look at Chapter 29 of the Software recovery handbook. It talks about replacing failed disks on Itanium boxes.

Hi Tony,

Here is a procedure for replacing the root / non-root disk on itanium using LVM.
