Hi experts,
One question regarding tape deferred mount and device allocation, supposing
following JCL statements:
//STEP1  EXEC PGM=ADRDSSU,REGION=6144K
//SYSPRINT  DD  SYSOUT=*
//ODOC1     DD  DISP=NEW,DSN=TEST1.FILE1,
//             LABEL=(1,SL),UNIT=VTAPE,RETPD=3,VOL=(,,,255)
//ODOC2     DD  DISP=NEW,DSN=TEST1.FILE2,
//             LABEL=(1,SL),UNIT=VTAPE,RETPD=3,VOL=(,,,255)
//ODOC3     DD  DISP=NEW,DSN=TEST1.FILE3,
//             LABEL=(1,SL),UNIT=VTAPE,RETPD=3,VOL=(,,,255)

Will JES2 try to allocate 3  tape deivces even the datasets are deferred to
mount(which is default when using stk vtss)? How to delay device allocation
before it is actually be opened?

Regards
Victor
