  • 1.  Renumbering hdisks

    Thanks

    extendvg rootvg hdisk0
    mirrorvg rootvg

    -> same for hdisk6

    The drives aren't mirrored. Hdisk6 is empty. I rmdev -dl hdisk6, and run cfgmgr, still comes back as hdisk6.

    lsdev -Ccdisk will probably show them as defined.

    rmdev the old disks and hdisk6 then cfgmgr and hdisk6 should come back as 0, mirror it to 5 and then unmirror 5 and you should have rootvg on 0, then rmdev and reconfigure 5 and it should come back as 1, don't forget the bosboot and boot list.
