FAULTY DISK replacement HP rx4640

Hello,

I'm new to this forum and as you will see from my question I'm new to UNIX as well.
One of our costumers has HP rx4640 running on UNIX with two 300GB hot-swappable disks that are mirrored. They reported to us that one of the disks is faulty and they want us to take care of it. Below is the only log they sent to us.

Code:

With my limited knowledge of UNIX i assumed from this that the disk ID is 13. If yes how do i find which of the two physical disk should be replaced?
And if i identify the problematic disk, are the below steps correct?

1) Check that the disk is not in the root volume group with lvlnboot -v command
2) continue with the disk replacement:

Code:

# pvchange -a N /dev/dsk/- # <replace the hot-swappable disk> # vgcfgrestore –n vg01 /dev/rdsk/- # vgchange –a y vg01

If I'm way off please inform me as i got all this from "When Good Disks Go Bad" and as i mentioned I have very little experience with UNIX.

Any help is appreciated.
Thanks Gjk
