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.
• The archive index has been destroyed and no suitable backup is available.
• FDS logging (discussed in FDS Logging in the Systems Guide), was not in place, and the FDS cannot 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 tape has not been written over yet, and one or more data sets must be restored.
