Question mirroring rootvg
I would like to konw wheather below steps are sufficient for mirroring rootvg.

Code:
extendvg rootvg hdisk1 
mirrorvg rootvg 

bootlist -m normal hdisk0 hdisk1 

bosboot -ad hdisk0 
bosboot -ad hdisk1

or anything needs to be added.

It should be enough.

And after all those steps, you'd better
reboot to disable quorum checking on rootvg. The mirrorvg turns off quorum by default, but the system needs to be rebooted for it to take effect.

Not necessary from 5.3 TL7 / 6.1 on.

Just to add, that I would probably do it this way:

Code:
mirrorvg -s rootvg hdisk91

to prevent sync'ing.

Then you can sync LPs in parallel:
Code:
syncvg -P 8 -v rootvg

(i.e. for 8 LP's in parallel)

LVM expects you to confirm 'recycling' of a formerly used disk by forcing writing new VG information onto it. man extendvg.

Be careful run lspv and check that hdisk1 is not already in another VG before you force it into rootvg!
