The optical indexes reside in the physical files QAMOVAR and QAMOPVR.
The QAMOVAR file is the optical volume index. It contains information about all optical volumes known to the system. This includes volumes that were previously removed from the optical media library with the volume description option of *KEEP. The QAMOPVR file is the optical directory index. It contains information about the directories on the volumes in directly attached optical media libraries or CD-ROM devices. This includes those volumes that were previously removed from directly attached libraries with the volume description option of *KEEP.
Information for volumes that are *OFFLINE or *REMOVED is retained by reclaim optical processing, but it cannot be rebuilt or verified because the physical volumes are no longer accessible. If the optical index database is ever destroyed, information about *REMOVED volumes can be recovered by adding the cartridge that contains the volumes to an optical media library using the Add Optical Cartridge (ADDOPTCTG)
