The CA Vtape dynamic LDS allocations requested by the SVTS and SVTSAS started tasks 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 SMS data class. Also, CA Vtape requests specific primary and secondary space values based on the CachePrimary and CacheSecondary attributes coded in its parmlib 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 cache allocations.
