Hi, I suppose VTS does the compression anyway, using DDR COMPACT or not. I have inserted the VTV- volumes as ECCST so they should be 3490(E). However, DFSMSRM Q VOL vollabel says my vols are 3480 (320MB) . The first volume fills after writing about 2800 CYLS, looking from the VTS LM shows that the volsize is 792MB (compressed).

I always abbreviate the option. I don't know if it defeats the compression. Maybe there's a symbiotic relationship between the hardware and software that they come to some sort of an agreement as to who does what. (sorry, been watching too many Star Trek and Terminator movies, et al). Steve From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Frank M.

A couple of questions. What are the virtual tapes defined as in the VTS? 3480's (I hope not), 3590's? ( "J" cartridge to be specific). Taking your comments literally, you did not use the COMPRESS option on the DDR statement. Using the compress option, I am able to get 10 (ten) 3390 mod 3's full packs on a single tape.

MAINT DDR SYS CONS IN 123 DASD OUT D3F TAPE DUMP ALL YES 3. After writing the first tape full, DDR want's the second one. How to mount it? The rdev d3f is attached to MAINT, so can't mount from another machine/user. MAINT is "in DDR session" so can't mount from there either. 4. The tapesystem is VTS using 3584 library. Any ideas how to get the following output tapes mounted? (I tested DDR output parm altape to write two tapes but then third tape was required and there I was again ... ) Thanks Janne J -- Kris Buelens, IBM Belgium, VM customer support Think green - keep it on the screen.
