Then you need to start RAID-5 on all DASD, and then add the non-configured DASD to the ASP. In the process of starting RAID-5 the system will do a reasonable job of scattering the objects. Adding this amount of DASD, I wouldn't do more. There is a DSKBAL command on V4R1 through V4R3 to balance disk utilization. (The command was added via PTF, so you may not have it.) I have not used it. There is a STRASPBAL command in V4R4 which I have tried, and it works reasonably well. I have never heard of a STRDSKRGZ command.
