Introduction:

How it is possible to exclude volumes or a storage group from PDS Compression?

Instructions:

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:

  1. 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 

  1. Copy the data set dsn.excludes to a parmlib member dsnexcl
  2. 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
