    I just noticed that we do have access to the mpathadm command by
    installing the "pkg:/storage/mpathadm at 0.5.11-0.151002" package. After
    installing I don't see any paths with "mpathadm list LU" which is what
    im used to on solaris 10 (i know I should be comparing to solaris 11,
    just havn't played with it much). I wonder if there are any other bits
    that I need to install or other configuration tweaks to get this going.

    Thanks in advance for any pointers,
    Majeed
