RE: V5R4 and 8GB drives

Chris,

If your load source is in an expansion tower, I would keep it there.
It's the best place for all your disks, especially if you are going to a
520, or if you have a 520 as you state. If possible, I always try to put
all my disks in an expansion tower. Remember, keeping it in the expansion
tower will make your migration to the Power6 520 follow on (when announced)
even easier. We can assume from your statement that you have an HMC, which
makes managing the box even easier. Last year I had an 820 with four
partitions. Three of them had all their disks in expansion towers. Do you
know, that we were able to detach the expansion towers from the 820, update
the HSL cards in the 5094, and reattach the expansion towers to the 520. We
had all 3 partitions up within 90 minutes. That is 90 minutes total, not
each. The other partition took us about 5 hours as we had the disks in the
820 CEC. There is nothing better then an i5.

JMHO

I would. I have never done a load source migration and I may have to do
that here on our production system when we rack mount our 520 with the
two attached towers. Our load source is in one of the expansion towers,
not the system unit.

What is your DASD utilization? What level of RAID are you running? How
many disks? I am in Northern CA.

Ah, if only you were local, Chris! I'm in Chicago.

But the idea is good. In fact, in addition to the prerequisite vittles,
I'd
be willing to pay a couple of benjamins to someone, provided they were
willing to walk me through the steps -- an instructor-led hands-on lab,
if
you will <grin>.

Where are you located? Sound like a great opportunity to outsource to
an individual like myself that has the hardware experience. If your
local, I would only charge a six pack and some pizza.
