Issue/Introduction
How is it possible to exclude volumes or a storage group from PDS Compression?
Resolution
Today there is no EXCLUDE parameter available with the SCAN or COMPRESS command to exclude volumes or a storage group from the PDS Compression utility, but you could use the following workaround:
Use the CMDGENDSN parameter of the REPORT command to generate a data set that contains entries consisting of the data set names that are to be excluded later from the PDS Compression utility: SCAN REALVOLS SELECT CRITERIA=(DSORG,EQ,PO) EXCLUDE VOL=(volsr1,volsr2,…),SGNAME=sgname REPORT MVD,CMDGENDSN=dsn.excludes
Copy the data set dsn.excludes to a parmlib member dsnexcl
Run the PDS Compression utility excluding the selected data sets by specifying the previously created member in the EXTABLE parameter of the SCAN command: SCAN VOLUMES=(/), DSNAMES=(/), THRESHOLD=(90,5,95,0,0), EMPTY, ALLOCATE=(80,10,80), EXTABLE=dsnexcl
