DASD Allocation Control Products

The CA Vtape dynamic allocations should not be intercepted or modified by DASD allocation control software other than SMS. Products which intercept space abends or adjust allocation amounts based on DASD pool conditions are not needed since Space Constraint Relief is coded in the DFSMS data class. Also, CA Vtape requests specific primary and secondary space values and takes appropriate actions when these amounts cannot be honored. Adjusting these values with another product could result in CA Vtape taking inappropriate actions or an ABEND.

Note: This restriction includes CA Allocate. The CA Allocate ASR should be updated to ignore all CA Vtape dynamic allocations.
