Each database backup volume contains a Tivoli® Storage Manager version number in the volume header. A mis-matched version number indicates that this volume is either corrupted or not suitable for restoring the database. This volume may be a pre Version 6.3.0 database backup volume. It cannot be used to restore a Tivoli Storage Manager V6.3 database.
The server does not process the DSMSERV RESTORE DB command.
Check the volume history file to make sure that this volume is a valid database backup volume. If this volume is corrupted, restore the database to a different time using a different set of backup volumes.
