John, A lot of SMS sites provide for multi-volume allocation in the default DATACLAS, but 40 would be unusually high Unit Count to provide all datasets.
SMS has not changed the way JCL works however, so if you need a multi-volume dataset with more volumes than the DATACLAS provides, you just use your own value in the Unit Count parm. I'd suggest omitting the ESOTERIC this may be restricted to a subset of available volumes in the SMS STORGRUP. The following JCL is what I would suggest using: //SYSREC01 DD DSN=IBMUSER.NDSP.DATA, // DISP=(NEW,CATLG,DELETE), // SPACE=(CYL,(2000,1800),RLSE), // UNIT=(,40) This is not an SMS problem. DATACLAS provides some defaults that reduce JCL coding, but if you want something other than the DATACLAS values there is nothing stopping you overriding the JCL.
