RE: V5R4 and 8GB drives

Thanks for the tip. Yes I have a 520 and I need to rack it. I also
have a 5094 and 5095 expansion towers. There is room in the 5094 to
hold everything in the 5095 so I can get rid of that tower. IBM does
not sell a conversion kit for the 5094 so I have to purchase a 1.8m 0594
tower and move all my guts there. I was also going to convert the 520
system unit to rack mount and put in the rack with the 0594 tower. That
is why I want the full 1.8m rack. I will be fun getting all the
hardware to be recognized in the new tower. Yes I have a HMC but I
really have not done anything with it. IBM set up the HMC when we move
from an 820 to the 520, migrating our load source to the drive in the
5095 tower, where it remains today.

Say how automated is it to move the guts and IPL? Will the system come
back up?

There is nothing better than an i5.

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.
