    Hello,

    a p650 has 2 internal scsi-controller.

    I noticed that on all of my p650 the 2 internal disks (rootvg) are
    connected to the same controller. Nothing is connected to the 2nd
    controller.
    If there are external (non ssa, non san) disks, there is a 3rd and 4th
    scsi-controller to which the disks are connected to.

    I see no point in connecting both rootvg-disks to the same controller as
    long there is an unused 2nd controller; neither regarding availability
    nor performance.

    But I dont know if this setup is shipped from IBM like this or if it is
    done somewhere @ ibm in my country.

    So, could you please tell me if your p650 have the same setup?

    If anybody got an idea about any advantage with this setup, please let
    me know.

    Regards,

    Holger
