The first thing I'd check is the Default Device Geometry defined in your
SMS Base configuration:
Mine:
Default Device Geometry
Bytes/Track . . . . . . . . 56664
Tracks/Cylinder . . . . . . 15
in ISMF - Option 8 Control Data Set
then Option 1 Display
Good Day All,
I am trying to allocate a dsn using PGM=IEFBR14 to create a dsn which of
25 cylinders. The dsn is SMS managed and it has GUASPACE as the Storage
Class. The DC & MC are null.
The dsn is allocated on the volume as requested however the space
allocated is 20 instead of 25. I was able to allocated the space of 25
cylinders when I coded UNIT=SYSALLDA,SPACE=(CYL,29),VOL=SER=PROM01.
Could anybody tell me where my error is? Below is my jcl (which is run
from a proc)
//*
//ALLOC EXEC PGM=IEFBR14
//A01065 DD &A01.DSN=&DSNIN..A01065,DISP=(,CATLG),
// UNIT=SYSALLDA,SPACE=(CYL,29),VOL=SER=PROM01
//IXX065 DD &IXX.DSN=&DSNIN..IXX065,DISP=(,CATLG),
// UNIT=SYSALLDA,SPACE=(CYL,29),VOL=SER=PROM01
//*
Below is the inquiry on the dsn:
