In your place I'd use a mirrored "rootvg" because "production system" sounds way to important to run the chance of a simple disk failure to play show stopper.

Having said this, if the two disks are in the same (root-)VG (as they appear to be) you can either create LV-copies on the other disk via LVM-mirroring, then, after syncing, break up the mirror and remove the copy on the disk you want to make free. Or you can use the migratepv to accomplish the same. Have a look at the man page for a detailed description.

I hope this helps.
