You could do that... or just create two separate LUN's in each
redundancy group and just use LVM to stripe across both LUN's. Beef
up the IO queue depth via the SCSICTL command in HPUX and you should
see a vast improvement in performance. Make sure you upgrade to the
latest firmware for the VA7400 also.
