Archive Index Rebuild Utility

A utility is available that can be used to recreate index records from the archive tapes (or archive data sets on disk) that contain the archived data sets. The support makes use of the control record and format-1 DSCB that are written with the data at the time of archival.

Use of this facility would be appropriate in any of the following situations:

• Restoring data sets at a site other than that at which the data sets were archived.
• FDS logging was not in place, or the FILES could not be fully recovered to a particular point in time.
• The index entries for a given volume have either expired or have been PURGED, but the volume has not been written over or scratched, and one or more data sets must be restored.
