Re: DDR to a second level system
Hello Tom, Not a problem. I have cp formatted, ddr copied, applied RSU/Corrective service. I am testing systems now. I will just CP format as a matter of fact.

Re: DDR to a second level system
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.

You probably don't *have* to do the format first, but if this is the first time the volumes have been used or if the volumes are recycled, it's still the Recommended Way (and will save you lots of semi-frantic debugging if something mysterious happens, especially if these will be page or spool volumes and you accidentally miss formatting a cylinder on the original volume you took the DDR image from). It takes extra time, but it's probably safer in the long haul. If it were my system, I'd still do the format first.
Re: DDR to a second level system
Hi Ed DDR ALL is an image copy. The contents of all tracks and all cylinders are copied. And you are aware that you only "need" to do a CP FORMAT for CP ONLY volumes. Regular CMS volumes nor other guest volumes need CP FORMAT done. Doesn't hurt, just a waste of time.

Re: DDR to a second level system
If you do a DDR DUMP ALL and then a DDR RESTORE it will take care of the formatting. On Wed, Apr 30, 2008 at 10:24 AM, Edward M.

ddr copies everything, you don't need to format the dasds. kind regards Franz Josef Pohlen Edward M.
