TRCASPBAL and STRASPBAL does not seem to work

["Mark A. Manske" <mmanske@xxxxxxxxxxxxxxxxxx>]

I have a few disks on a 820 at V5R1 that are being used much more
heavily than most others, thus hampering performance.

I had run the TRCASPBAL for a week to collect data, then we
IPL'd and I had set things up in the startup to do the STRASPBAL,
it ran for 1 second - and did nothing.

I looked through the archives, and on IBM's manuals which dragged me
to the Hierarchical Storage Management manual -

None of which told me anything I did not already know, I am wondering
how the following commands "appear" to have done nothing -
note, these ran under QSECOFR user, and shows in the QHST log
that the ASP trace started, there is no log entry showing that it ended...

On 11/23/2002 I ran the following command-

TRCASPBAL  ASP(*ALL) SET(*ON) TIMLMT(9999)

and the next Saturday I ran the following command -

STRASPBAL  ASP(*ALL) TYPE(*USAGE) TIMLMT(1800)

I set a time limit of 1800 so as to allow time to let system settle down
before the Sunday shift started working.

Due to budget constraints and sporadic growth, we have a varied
collection of disk packs - as follows:

              Size
 Unit  Type    (M)
    1  6717   6442
    2  6607   3670
    3  6607   3670
    4  6607   3670
    5  6607   3670
    6  6607   3670
    7  6607   3670
    8  6607   3670
    9  6607   3670
   10  6607   3145
   11  6607   3145
   12  6607   3145
   13  6607   3145
   14  6607   4194
   15  6607   4194
   16  6713   6442
   17  6713   6442
   18  6713   6442
   19  6713   6442
   20  6713   8589
   21  6717   6442
   22  6717   6442
   23  6717   6442
   24  6607   4194

Any thoughts as to why this did not work for me "as expected" -
I was hoping to balance the work load of the heads/packs; some run at 0% to
5%,
and just five to six will run at 70%-90% during many runs that we have going
in
batch all this while the CPU utilization is at 40% or less.

TIA
