Dave, It was way back on the 7700E when HDS decided that using PPRC commands to manage Shadowimage volumes would be a handy thing. In its simplest form the Control Unit looks at the serial numbers of the Source and Target volumes in the PPRC command and if they are the same, and Shadowimage is licensed, then it will be processed as a Shadowimage command. For most cases TrueCopy and Shadowimage volumes can co-exist in the same Control Unit and be managed with PPRC commands.
Of course TC and Shadowimage are now doing things that PPRC commands are not designed to handle, which is why we prefer customers to move to Business Continuity Manager. If you are licensed for Shadowimage and your current procedure works then there is no need to change, as the PPRC commands support most of Shadowimage's capabilities. If you want a simpler way to maintain and manage this then you may want to look at BCM - I get a lot of positive feedback about the ISPF interface and the simplicity incorporating the COPYGROUPS into REXX. FlashCopy provides some innovative integration with DFSMS STORGRUPS and DFSMShsm, as well as Dataset Level capabilities that may be a better mousetrap for your shop. You do not need PPRC commands or BCM if you use FlashCopy on HDS. In most cases it should inter-operate transparently with ANTRQST and ICKDSF FC* commands and DFSMSdss.
