Hi Glen,

Thank you for the advice. The HMIG commands worked perfectly. I would just like 
to see how PRIMARY SPACE MANAGEMENT invokes the ACS routines when the data sets 
become eligible for transition.

Where is 'SPMGCLTR' being picked up? Is it a setting that has been part of 
DFSMS since z/OS 2.1?
What is difference between CTRANS and SPMGCLTR?

Regards
Theo

Subject: Re: Example of ACS Environment of SPMGCLTR

Hi Theo,

Change:
 IF &ACSENVIR = 'SPGMCLTR' THEN
  SELECT (&MGMTCLAS)
    WHEN ('USRTIER1') 
      SET &MGMTCLAS = 'USRTIER2'
      OTHERWISE SET &MGMTCLAS = &MGMTCLAS
   END

to:

IF &ACSENVIR = 'SPGMCLTR' THEN
   SET &MGMTCLAS = 'USRTIER2'
END

This obviously overly simplifies it, unless you only plan on making the change 
to one management class.  Unfortunately, with the current limitations, you may 
not have access to the RO variables that you need to add the correct logic.

I also forgot to point out that we shipped a Development APAR OA47700 that 
enables you to override ACS logic and just specify MC, SC and / or storage 
group on the various Migrate Transition commands.  For example, you could 
transition a data set to just a new storage group with the command HMIGRATE 
DSNAME(... ) TRANSITION(STORAGEGROUP(Nearline)).

If you'd like to set up a conference call to discuss your options in more 
detail, you can email me at [email protected].

Glenn
