Hello Tom, As I read the DS6800 manual, it seems that the initial format was suppose to do all these neat checks.
The 2nd level system is mine for support and fun stuff. I had the improper format problem on the older EMC dasd. Really interesting abends and problems. I am getting a read on 'NO FORMAT' required.
