    Each node will have its own vg00. This usually consists of the onboard
    disks only and holds the OS and swap space.

    There may be other "local" vgs, which will hold stuff exclusive to
    that node, depends on how it was set up.

    Each application package has its own set of 1 or more vgs which will
    be activated on the node running the package. These vgs will be
    deactivated when the package is halted. They are only visable on the
    node running that package, although defined to all hosts.

    Regards,

    Ted.
