Re: rootvg Mirror

You mirror LV's not disks. So as long as there is enough room on
hdisk1 to mirror all LV's on hdisk0 then you are ok. Obviously you
could wind up data on hdisk1 that can't get mirrored to hdisk0 if it
gets full. Mirrorvg is just a script that mirrors all the logical
volumes with mklvcopy.

Can you mirror two different size disks in rootvg? For instance, hdisk0
is an 18 GB drive and hdisk1 is a 36 GB drive. Can you mirror hdisk0 to
hdisk1? Any pros / cons to doing this?
