VALIDATE

VALIDATE on a logical data set dump, specifies that all indexed VSAM data sets are to be validated as they are dumped. If the NOVALIDATE keyword is specified, the indexed VSAM data sets are dumped without validation. VALIDATE is the default.

Note:

If an indexed VSAM data set is dumped using VALIDATE, it must be restored on a system that supports VALIDATE. Otherwise, an error message is issued, and the restore fails.
Do not specify the NOVALIDATE keyword when processing VSAM extended-format or extended-addressable data sets.
When a data set is restored, the free space in the control areas and control intervals are reset to the values in the catalog entry. You can override the values in the catalog entry by specifying the FREESPACE keyword on the restore.
Use the NOVALIDATE keyword on the DUMP command if you wish to restore to a DFDSS Version 2 Release 5 system that does not have the appropriate VALIDATE support, or to any level of DFDSS prior to Release 2 Version 5.
