RE: 70GB load source and 5 other drives



fixed

Yes, the CTL 0 is the first disk, and the Load Source.

Ok, since they all look alike to me, do I just pick the one with "Ctl" = 0?
Or should I fire this up with just one storage space initially to make sure I grab the right one?


Select Load Source Device

Rob,

7.2 will need a 70GB load source, and that means when you
create it on the guest side you have to create it larger than 70 to get 70
on the hosted (or client) side. I have been using approximately 79GB when
I create them, and they have worked fine for 7.2. Then if the others are
significantly smaller, I end allocations on that drive to keep the I/Os
more balanced on the spread of the I/Os across the drives

I know that we covered this in a thread but I'm having a devil of a time
finding it. I found it alluded to in
http://archive.midrange.com/midrange-l/201401/msg00542.html

I have a guested system that is currently 279GB. And it's only 30%
utilized. I am doing an unload/reload and I want the 6 "luns".

I figured that I'd make the first one slightly over 70GB (like 75 or 80).
The reason being that it is a very hard halt with the next version of OS,
especially with virtualized disks, and IBM will publish the 'pad' needed
for VIOS, etc.

~300GB - 80GB = 220GB
220GB/(5drives/GB) = 44GB/Drive
So am I better off having 5 'luns' of 44GB each, or,
220GB/(35GB/drive)~=6 drives of 35GB each and having 6 drives of a
somewhat standard size?

Or refigure the whole thing since it's only 30% utilized.
279 * .3 = 81GB

80GB load source and how many of what size additional CRTNWSSTG spaces?
Cause you can see just how much wasted space I'll have with 6 drives of
80GB.
