    Thanks to all who replied (Tom Payerle, Victor Engle, and Vincent Bolay).

    Initial problem: multipathing/failover with a dual HBA from Emulex (the
    LightPulse LP9802DC).

    Suggestions received:

    1. Look at Veritas Volume Manager
    2. See what your storage vendor has in the way of RDAC drivers

    Also, multipathing is less of an issue than failover.

    Action take:
    1. Downloaded IBM RDAC driver for FAStT (taken from the FAStT Storage Manager
    package)
    2. Installed
    3. Failover works on a very limited basis (see below)

    Current problem:
    1. Panic when data is copied onto new SAN partition

    I can run newfs, mount the filesystem, touch a file, and list the files on the
    new filesystem. I can even pull cables and it will failover (i.e., I can
    continue to do a file listing). But when I attempt to copy a file onto the new
    partition it panics.

    Anyone see this before? I am not getting a lot out information from
    /var/adm/messages, etc. This is Solaris 9, and I am looking into kernel patches.
