The SMC DFSMS interface may select incorrect POLICY, MANAGEMENT CLASS, MEDIA or RECTECH.
SMC may pass to DFSMS the unit address in place of the ESOTERIC or GENERIC under the conditions as noted. If the ACS routines do not account for the unit address to be passed in the &UNIT field then the ACS routines may not match for the mount and incorrect information from the ACS routines may be returned to SMC. This may cause SMC to select an incorrect POLICY, MANAGEMENT CLASS, DATA CLASS, MEDIA, RECTECH..
WHEN &UNIT = &TAPE
SET &DATACLAS = '36TRK'
SET & DATACLAS = '18TRK'
In this case if the VSM unit 9000 is passed to the ACS routine the DATACLAS of 18TRK will be assigned rather than 36TRK as it should have been.
The SMC DFSMS interface is utilised.
The DFSMS ACS routines perform determinations on &UNIT.
The &UNIT determinations compare with a GENERIC or ESOTERIC unit name but NOT a unit address.
BPXBATCH is run in an earlier step or the allocation is within the BPXBATCH step.
