Maximum Size on One Volume
Many types of data sets are limited to 65␠535 total tracks allocated on any one volume, and if a greater number of tracks is required, this attempt to create a data set will fail.
Data sets that are not limited to 65␠535 total tracks
allocated on any one volume are:
- A large format sequential; but cannot occupy more than 16␠777␠215 tracks on a single volume.
- Extended-format sequential
- UNIX files
- PDSE
- VSAM
If a virtual input-output (VIO) data set is to be SMS managed, the VIO maximum size is 2␠000␠000 KB, as defined in the Storage Group VIO Maxsize parameter.
