    Hi All, We are doing some testing with omniOS in our datacenter and
    would love connect it up to our compellent san via fc connectivity. I
    slapped omniOS onto a dell r610 that has a qlogic dual port hba (each
    port is pathed to separate fabrics), performed zoning in each fabric,
    and assigned some luns. Now im not sure if compellent supports Solaris
    11 (i can contact them and see about that), but it definately support
    solaris 10 which is what we use on other production systems.

    I'v actually made it pretty far through the process which is really
    exciting, except for the last multipathing bit. After mapping a volume
    to the host I can't seem to condense all the devices down to a single
    mulipathed device. It seems multipathing is enabled for the fp driver. I
    noticed there is not a mpathadm command.

    Anyone have any ideas? I'll post some output from the commands i think
    of below. Let me know if you would like to see any other information.

    Thanks much,
    Majeed

    On solaris 10 the main thing we have to do is add the following to
    /kernel/drv/scsi_vhci.conf (reconfigure reboot)
    device-type-scsi-options-list =
    "COMPELNTCompellent Vol", "symmetric-option";
    symmetric-option = 0x1000000;

    Here is the format output:
