    Hi John.
    You can add to your /etc/modules.conf:

     options scsi_mod max_scsi_luns=n

    Where 'n' is the maximum number you want the kernel to probe for.

    Then rebuild the initrd for the kernel.
    A simple way to rebuild the initrd:

    new-kernel-pkg --mkinitrd --depmod --install `uname -r`

    This will create a new initrd for the currently running kernel BTW.

    You can find a little more detail about why this is necessary by
    visiting the Red Hat Knowledge Base https://kbase.redhat.com and do a
    search on 'SCSI LUNS'

    Cheers,
    Michael
