Nick,
First bring in the disk, after mapping the disk on VIOS, run cfgmgr and you will see the new disk.
Steps:
1. run cfgmgr
2. change the disk attributes if any (like hcheck_interval time etc..,)
3. extendvg the disk to rootvg by running extendvg rootvg hdiskX (where X=disk no)
4. now mirror the disk, mirrorvg -S rootvg hdiskX (-S flag tells to sync in the background). It will return soon, but will take some time to sync all LV.
5. now check for mirror, lsvg -l rootvg (you should see PPs=2) and LV STATE=open/syncd
6. if at all you see any stale LV's use syncvg -v rootvg and that should sync then.
7. verify the bootlist, run bootlist -m normal -o

Hello,

thanks for the quick response

Once all is mirrored do I need to also perform the following task?

• Run a bosboot on both new disks, this will install all software needed for boot on the disk
o bosboot -ad hdisk0
o bosboot -ad hdisk1

Oh, that was suppose to be my 7th step, I missed it and listed bootlist on it.

Any ways!! good luck.

me again,

So just to be 100% sure, do I run the bosboot -ad command on both of the root disks or just the mirror i.e hdisk1 ?

Cheers

Nick

No harm in running on both disk. Also make sure you see hd5 on both disks.
you can add by running bootlist command.
