Hi,

I need to upgrade from 5.2 to 5.3, I have 2 hisks mirrored currently in
rootvg, I am having problems understanding how I can clone hdisk0 to
hdisk 1, so I only upgrade one of the disks.
Is there any docoumentation somewhere, that is idiot proof !

Thanks
Pete

You will have to unmirror one of the disks and make one free , And if
I am right there is a nim command ( for eg:- nimadm which I used for
upgrading to 5.2) where in you need to specify what type of
upgradation and the destination disks, which will clone by itself to
the targeted disks and perform the upgrade on it.

Lets gather other comments as well.

chapter 13 of the AIX 5.3 Installation and Reference Guide talks about alt disk migrations.
