Gerry,

Are you using NON SMS managed DASD, or SMS managed ?

Hi Expat,

I made sure I used non sms managed volumes. when I tested against SMS managed volumes the catalog only showed 1 volume.

OK OK, only asking icon_biggrin.gif

The problem is with the way that the file has been set up, and/or used. It is pre allocated for the second and subsequent steps, and as stated in my post above, will not extend on the first and second volumes.

Methinks that your use of DISP=MOD would be the best solution, except that I'm never happy using DISP=MOD. Probably stems from my early years when hardware and media were not so damned reliable.

Hi Expat,

I agree with you with DISP=MOD, the minute it runs out of space the file is useless, some of the data has already been appended. icon_smile.gif icon_smile.gif icon_smile.gif

Yeah, and a couple other places too icon_wink.gif

Maybe this is a job for GDG man !!!! Probably the best way forward, using RLSE with the space so no over allocations and no need for MOD.

Hi all,

Thanks for all of your messages.

I finally found that it should be caused by a FEOV macro. I am going to use storage pool instead of delicated volumes to sovle the problem.
