1 Build the library inventory.

To initially load the library manager inventory in an ATLDS, insert tape cartridges into the library storage slots and start the teach operation at the library manager console. In a virtual tape server (VTS) library, the logical volumes are identified at the library manager console through volume serial number ranges. All cartridges are placed in the insert category by the library manager for later cartridge entry processing by the host. It is later during OAM address space initialization and the host going through vary online processing that the cartridges in the insert category are processed and the records in the TCDB are created. As the host processes each cartridge in the insert category, the cartridge entry installation exit (CBRUXENT) is invoked to approve or deny the entry of the cartridge.

If the volumes in the library are shared between an MVS and a non-MVS platform, see Sharing tape volumes between an SMSplex and a non-MVS platform. If the volumes are already owned by a non-MVS platform and are no longer in the insert category, the TCDB volume records must be manually created in order for MVS to have use of the volumes. Because this bypasses the Cartridge Entry Installation Exit, the volumes may also need to be added to your tape management system.

To initially load the MTL inventory, the general use programming interface, CBRXLCS FUNC=MCE, or the LIBRARY ENTER command may be used. Also check with your tape management system to determine what support they may provide for building the MTL inventory.
