Thank you for bringing this to my attention. These are the filterlists I
have defined:
FILTLIST DASD_UNITS INCLUDE('3390','SYSDA','SYSALLDA', '')
FILTLIST TAPE_UNITS INCLUDE('3590*','MAGSTAR','T3590')
FILTLIST DB2_VOL INCLUDE(* )
In the select logic I check for the dataset name being passed and the
DASD units. So could I get burned by this example ?
We don't SMS manage any tape and the filter list defined for the tape
units is no where in the logic. We just defined it in the event we might
use it someday.

Dean, there's may be an unintended consequence to be careful of now that
you added null to the list of valid unit types.
If you have a job that stacks datasets on a single tape volume by using
UNIT=AFF=ddname such as the following:
//TAPEV01 DD DSN=SDR.BKUP.ML1001(+1),DCB=(SYS2.DSCB),
// UNIT=LTAPE,DISP=(NEW,CATLG),LABEL=(1,SL),
// VOL=(,RETAIN)
//TAPEV02 DD DSN=SDR.BKUP.DBA002(+1),DCB=(SYS2.DSCB),
// DISP=(NEW,CATLG),LABEL=(2,SL),
// UNIT=AFF=TAPEV01,VOL=(,RETAIN,REF=*.TAPEV01)
The ACS routine will have null for the unit for TAPEV02 .
I burned myself by changing an HLQ from non-SMS to SMS managed, and with
the logic as it was in my SMS routines, I was setting a storage class
for the second tape data set (we don't SMS manage tapes) and the
allocation ended up failing.
May not impact you at all, just something to look to make sure it
doesn't bite you.
