Questions:

Is there a way we can allocate an SMF dataset of 10.000 cylinders?
If there is no way to allocate such a dataset, how do you suggest to
deal with this problem?

Standard VSAM has a limit of 2GB.
With an extended format file you can go to 4GB times the CI-size (4K in SMF's 
case).


Or, you can allocate more of them at 2GB.

Or, dump more frequently.

TeD,
AFAIK standard VSAM limit is 4GB (or 4GiB for purists).

2GB is (was) the limit for unix files (not only USS under z/OS, but also AIX, HP-UX, ICL NX etc.). It was also the limit for HFS (I'm not sure about it, but I found such information in IBM materials).
