Examples of the STORCLAS parameter

Example 1

//SMSDS1  DD  DSNAME=MYDS1.PGM,STORCLAS=SCLAS01,DISP=(NEW,KEEP)

In the example, SMS uses the attributes in the storage class named SCLAS01 for the storage service level of the data set. Note that installation-written ACS routines may select a management class and data class and can override the specified storage class.

Example 2

//SMSDS2  DD  DSNAME=MYDS2.PGM,STORCLAS=SCLAS02,DISP=(NEW,KEEP),
//          VOLUME=SER=(223344,224444)

In the example, SMS uses the attributes in the storage class named SCLAS02 for the storage service level of the data set. Also, if the storage administrator has specified GUARANTEED_SPACE=YES in the storage class, VOLUME=SER can be coded and the data set will reside on the specified volumes. (However, if space is not available on the volumes, the job step fails.) Note that installation-written ACS routines may select a management class and data class and can override the specified storage class.
