    I would do similar to Jason but a little different:

    Break the mirror, move all data to one drive, remove empty drive from vg,
    rmdev empty drive, physically remove empty drive, put new drive in, cfgmgr,
    extendvg, mklvcopy old drive to new drive (to re-establish the mirror),
    rmlvcopy old drive, rmdev old drive, physically remove old old drive,
    insert second new drive, extendvg to second new drive, mklvcopy to second
    new drive.

    Break the mirror, move all data to one drive, remove empty drive from vg,
    rmdev empty drive, physically remove empty drive, put new drive in, cfgmgr,
    extendvg, migratepv data to new drive, repeat for second drive, mirrorvg

    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
