DRM has such a tool indeed, but requires manual intervention, you move minidisks one by one. It exists in two flavours: a 3270 interface a CMS/GUI interface (DRMGUI package) The first one lack userfriendlyness (somewhat caused by the 3270 limitations). The CMS/GUI interface is much nicer, but it suffers from bugs in the CMS/GUI WSA. I do have a more recent version than on VM's download lib, contact me if you are willing to install the WSA, lack of time to finalize the newer version made it is not on the WWW yet, but is is *much* better, I found a way to bypass some WSA bug with cursor placement.
Both work better when you have DFSMS, you don't need ISPF, just DFSMS and its worker machines SMSMASTR and DGTSRVxx. The reason it works better with DFSMS is that my tool reads the DFSMS results files sent to your Reader. I do not try to intercept DIRMAINT's messages to see which moves worked or failed. I use it (the CMS/GUI version) when I need much space for new VM releases etc. Kris, IBM Belgium, VM customer support > Take a look at DRM on the VM DOWNLOAD pages.
