Introduction of this new feature in no way prevents you from continuing centralizing SMS and non-SMS data set allocation management in BrightStor CA-Allocate without the need to implement DFSMS ACS routines. Existing code can "SET" multiple SMS SGs in the ACS Environment the same way it can set multiple NonSMS-ones in the ALLOC, DEFINE, EOV, and EOV_VSAM Environments.
DFSMS will select a volume from the ESG only when the data set already has candidate volumes in excess of available volumes in SMS SG it was originally allocated in. There are three ways to insure a data set has available candidate volumes. Either via he new DYNVOL parameter, the old unit-count JCL parameter, or BrightStor CA-Allocates existing End-Of-Volume Support for SMS-Managed data sets.
