1. Take full vg00 ignite backup
2. Shutdown server, remove both old disks, insert both new bigger disks
3. Recover vg00 ignite backup
4. Setup alternate boot disk to with LIF and mirror to primary boot disk
Is there anything else that's needed in this process to achieve the same vg00 setup on the new bigger disks?
Solved! Go to Solution.

SolutionSteps 1-3 are fine.
You can manually intervene in the Ignite process and set up vg00 to utilize increased space if you wish.
Then do step 4.
Ignite make_tape_recovery will back up and restore mirror boot disk configuration as well.

Re: Replacing boot disks
do exactly what you wrote...but like Steve said, intervene during recovery process to utilize your full disk space.

Re: Replacing boot disks
reduce the mirror, replace the disk with bigger disk, re-add the bigger disk to vg00, follow the root vol mirroring procedure.
When done repeat the process for the other disk.

Re: Replacing boot disks
Really? I didn't think this process you mention would allow me to fully utilise the bigger disk. I was always under the impression that a volume group has to be created with the biggest disk first, if you therefore add a larger disk later on it will only recognise the initial disk size, the rest will be ignored. Or am I wrong?

Re: Replacing boot disks
You may not be able to change the size of the stand and root logical volumes because they need the contiguous free PEs due to contiguous allocaction policy.
BUt as you do not need to extend the size of the lvols of vg00 . you can simply go form mirroring and replacing the smaller disk with the large one.
