Hi
I would suggest having as much volumes as possible. This is because AIX
treats every volume as a PV, and one PV can only do one write or read at a
time.
So, using 24GB volumes is probably the best way to go. Also, JFS
formatted volumes is the way to go.

Subject: Defining TSM Disk pools on ESS wisdom wanted
Hi,
We are redefining our TSM disk pools on IBM ESS storage. We got 39 x 24 GB
LUNs from our storage collegues. Total 936GB.
LUNs are spread across the whole ESS. Now what is the best way, TSM wise
and
performance wise to define these disks to TSM?
Make the volumes as large as possible?
or define a volume per LUN, so I get 39 volumes of each 24GB?
Use raw volumes or JFS formatted?
Almost forgot: we're running TSM 4.2.1.9 on AIX 4.3.3 ML10 (yes I do
know....All going out of support soon).
ESS is FC connected.
Thanks all for your eternal wisdom,
