    You said you wanted to get rid of this vg and rebuild. You should be
    able to exportvg this vg to rid yourself of it.

    I tried the following that is supposed to ignore quorum and this is what
    I
    got:

    # varyonvg -fu pdxvg
    PV Status: 00201337f771271e PVNOTFND
                            00201337f7ca7ed0 PVNOTFND
    0516-013 varyonvg: The volume group cannot be varied on because
            there are no good copies of the descriptor area.

    Can you not force the vg to vary-on? Can you turn off quorum and then
    try to vary-on the vg?

    Hello All,
    I have an F40 with a raid controller and two internal raid 5 arrays.
    One
    array in each of two six packs (hdisk6 and hdisk7). Each array has 6 18
    gig
    drives. I have been having problems with a drive in hdisk7. and today
    the
    system crashed. When the system came back up nothing would mount. I
    look
    at the array status and it was showing only hdisk7 but with the drives
    from
    hdisk6. hdisk6 was channel 1 with 18, 19 1A, 1B, 1C, 1D and hdisk7 was
    channel 2 with 28, 29, 2A, 2B, 2C, 2D. Now it shows hdisk7 with 18-1D.
    I
    decided to wipe out the filesystems, volume group (which had hdisk6 and
    hdisk7). Remove each array and re-make the arrays. Somehow the volume
    group is varied off and when I try to varyonvg pdxvg it tells me quorum
    problem, not enough disks. I cannot remove the filesystems because it
    says
    I have to have the volume group varied on and I can remove the volume
    group
    because it cannot remove the logical volumes. Does anyone know how I
    can
    get rid of this volume group and filesystems??????

    Thanks,
