    Are the new drives the same size as the old drives? PP sizing depends upon
    drive size. I ask because normally you don't replace 2 working drives unless
    you are increasing space. If you are increasing the drive size, look at chvg -t
    command.

    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
