In this example, an extent pool configuration summary status report of the storage control unit oriented by a particular device is requested.

     //LDEPCS   JOB   ...
     //STEP1    EXEC PGM=IDCAMS
     //SEFLC1   DD   UNIT=3390,VOL=SER=SE7A53,DISP=SHR
     //SYSPRINT DD   SYSOUT=A
     //SYSABEND DD   SYSOUT=A
     //SYSIN    DD *
        LISTDATA EPC SUMMARY FILE(SEFLC1) 
     /*

The SEFLC1 DD statement specifies a 3390 unit for which extent pool configuration summary status is reporting. The LISTDATA command parameters are:

• EPC, which specifies that an extent pool configuration status report is printed.
• SUMMARY, which requests a summary report for each of the extent pools configured on the subsystem.
• FILE, which specifies SEFLC1 as the DD statement that allocates a 3390 unit and volume SE7A53. The device specified in the DD statement is used as an I/O device to obtain an extent pool configuration status.
