    Hello Sun Gurus,

    I currently have a problem I can't seem to google/find in the archives. I
    need to grow a mirror set d66. This set is currently sitting on 2
    concatenated devices, which sit on 2 soft partitions. I know I need to
    grow the soft partitions, but everything I've read in Sun Docs, says I
    can't do this if I've created another device from the soft partitions. Is
    it possible to create a soft mirror(Mirror in Volumn Manager) and then
    create soft partitions on top of that mirror set, or does the mirror need
    to be a hardware based mirror. Any help would be great. I've included the
    dump from metastat d66 at the bottom.

    d66: Mirror
        Submirror 0: d16

        Submirror 1: d26
