I know that smf collects everything
SMF only collects what it is told to.
Your scheduler may (or may not) write SMF (user) records.
And, SMF may (or may not) accept them.

Ted,
It was not DB2 that had a problem. It was CICS and a few batch jobs. I don't
have a problem with multi-volume datasets at all, and in fact I design SMS
to allocate large datasets on as many volumes as possible. It was simply
having so many candidate volumes for every dataset, 1 track or 1

Seriously, can any shop beat 10 years of continual VTS B18 Operations?
Not a competition, just out of interest.
1. It has nothing to do with VTS, except the fact VTS uses real drives
in real 3494 library. So the problem regards 3590 drives in the library.

Most people are running on VIRTUAL disks anyway. z/os may see a 2105

RAID 5 on the SAN so it doesn't much matter any more. We used to place
datasets on disks in accordance to their activity level and distance
from the VTOC. To

Okay. I stand/sit corrected.

I didn't think you did have a problem.
The issue is
TIOT
A lot of SMS sites provide for multi-volume allocation in the default
DATACLAS, but 40 would be unusually high Unit Count to provide all
datasets.
Why?
I've worked in shops that set the default, through ACS, to the max (59).
I would also be careful with just setting the max (been

We're not talking performance, here.
We're talking space, volumes, TIOT (Task I/O Table).

Ken,
I think I have a bit of an understanding about virtual arrays. Unfortunately
allocation doesn't, and shops without PAV still suffer from IOSQ.
And I still open the doors up to see if there some sort of IO skew happening
- flashing lights still tell you something about destage and cache miss
The TIOT concern is related to the DVC value rather than the volume
count value. The DVC total is counted whether or not the dataset
extends to that count total. Whereas the volume count is recorded in
the catalog as candidate volumes.
