I agree. One argument that I have gotten in the past was "but I can easily
allocate an HFS filesystem using simple JCL. To allocate a ZFS, I need to
run an IDCAMS, then the initialization program. What a bother!". Well,
assuming that your ZFS data sets are SMS managed, you can easily allocate
and format a ZFS data set using simple JCL too! I use:
// SET FS= DATA SET NAME
//MKZFS EXEC PGM=IOEAGFMT,REGION=0M,
// PARM=('-aggregate &FS -compat')
//ZFS DD DSN=&FS,
// DISP=(NEW,CATLG),
// UNIT=SYSDA,
// SPACE=(CYL,(200,100)),
// RECORG=LS
//SYSPRINT DD SYSOUT=*
//STDOUT DD SYSOUT=*
//STDERR DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//CEEDUMP DD SYSOUT=*
//*
The only changes are to the // SET FS= to set the DSN name. And perhaps to
change the SPACE= in the JCL. "Easy, easy!" as my Russian teacher would say.

This is a test of the Emergency Broadcast System. If this had been an
actual emergency, do you really think we'd stick around to tell you?
