AIXites,

Here's what I'm trying to do:

I have two VG's with one 80G non-striped LV/FS each laid out some
storage, spanning 5 PV's each. I would like to mirror these into
another VG with existing LVs, striping the 'old' LVs in the processes
over the 4 PVs that this VG encompasses. Is this possible without
rebuilding the LVs as striped first?

Thank you very much in advance!

You can only mirror within the same volume group. So you would have to
remove the LV's and filesystem on the disks you want to mirror onto,
then reducevg to remove the PV's from the VG, then extendvg.

This will not allow striping though, you would have to backup the
data, delete the LV's and recreate them with striping and then restore
the data.
