Reblocking during recall

The purpose of reblocking is to make the most efficient use of available space on your DASD. Physical sequential data sets are moved with DFSMSdss. Specifying SETSYS CONVERSION(REBLOCKTOANY) will cause them to be reblocked during recall.

Nonkeyed, blocked, physical sequential data sets that were migrated with DFHSM 2.6.0 (or an earlier release) are also reblocked during recall when SETSYS CONVERSION(REBLOCKTOANY) is used. Partitioned data sets (DSORG=PO) are not reblocked during recall.
