This is my first experience with these volumes and I have a little
problem. There was a requirement to use these mod 9 volumes so our
customers could dump very large files to these packs. These two volumes
are SMS managed. The first test failed with a E37. The JCL contained
space(cyl,(3000,1000)). It allocated only 4000 cylinders on the first
volume, switched to the second volume and allocated another 4000
cylinders and then abended. Is there something in the JCL that needs to
be coded to make the system understand these files are allowed to go
beyond the default size.
We are z/OS v1r7.
Any help would be appreciated.
This is due to limit of 64k tracks per volume, regardless of extents. PS datasets cannot be larger.
However you can use other kinds of PS datasets:
1. Extended format PS. It can be larger, it can have up to 123 extents per
volume. It cannot be used by ADRDSSU as a dump file.
2. Large PS. New thing in z/OS 1.7. AFAIK it can be used with ADRDSSU. It can
be larger than 64k tracks, but it still has 16 extents per volume.
Last but not least, you can use more volumes per dataset i.e. code VOL=(,,,8)
or use Dynamic Volume Count, however this method does not allow you to use all
the space of mod-9 for single dataset.
