    I have a "datavg" volume group that is mirrored from hdisk2 to hdisk3 on
    a 7026 B80. These internal disks are both 18GB scsi drives and I just
    rec'd 2 new drives to replace them. There are no extra drive bays in the
    server. I figure I will need to back up the vg with savevg and then swap
    the drives and do a restvg which I've never done or could I break the
    mirror and the swap 1 drive and remirror and then the other?

    What would be the best/easiest way?

    TIA
