I created a zFS that occupied most of a 'Mod-27'. The IDCAMS step to create the underlying VSAM cluster looked like this:
DEFINE CLUSTER (NAME(xxx.ZFS) - VOLUMES(vvvvvv) SHAREOPTIONS(3) DATACLAS(EXT) LINEAR - CYLINDERS(28000,100)) The key is DATACLAS. 'EXT' is the name we use for extended data sets in SMS. Once the cluster was defined, the zFS formatting was the same as for any zFS: //FMTVSZFS EXEC PGM=IOEAGFMT,COND=(0,LT), // PARM=('-aggregate xxx.ZFS -compat') //SYSPRINT DD SYSOUT=* //SYSOUT DD SYSOUT=* //STDOUT DD SYSOUT=* //STDERR DD SYSOUT=* . .
