What happens to a PV on a hardware RAID-5 device that is presented to the system as a single (say scsci) target when you put a few more disks in it and tell the hardware raid device to add them to the given (scsi) target that a PV was created on? (what a mouthful). Is this really possible or can one only expand a hardware raid array for LVM usage by adding additional raid targets and then adding the raid targets as PVs to a VG? b.
