Can we create an LPAR for testing on a relatively small machine? Any
thoughts from hardware experts would be appreciated, before we starting
digging into the manuals...
Here’s the picture:
We have a 520 M25 running V6R1, 1 processor, 16GB memory with plenty of
spare CPU time.
We have 12 4328 disk units at Raid 5. 8 are 120mb, 4 are 100mb, for
over 1 TB of space. We could devote 25% of this to a test LPAR.
I believe we could share the CPU so that the existing production
partition would rarely be impacted (it would always get priority for
cycles).
But can we realistically split up 12 drives so that 25% goes to a new
LPAR? For continued production performance I think we’d want production
data spread across all 12 units.
Back in a former life on an earlier OS with much bigger machines, IIRC
we needed a separate disk controller for each LPAR, but I was much
further removed from hardware nuances then. (I'm still not all that
close...)
Thanks, Sam
