The Question is: I have a tl891 library with a single TZ98 drive connected to a DS20E (SCSI connection). No problem accessing tape-by-tape using MRU, but if I need to access a number of tapes unattented (a BACKUP requireing >1 tape), this is not sufficient. I installed an d configured MDMS to intercept and react on the OPCOMmessages but it fails. OPCOM messages are either not signalled or reacted upon. A manual LOAD VOLUME command only changes data in the MDMS database but will NOT access the library, seems to wait for som ething but I can't figure out what. Any idea what to look for? The Answer is : BACKUP can normally sequentially load and unload tapes from a tape library, assuming that the library itself permits such an operation. It appears you have encountered a problem with MDMS software, or that you do not have the TL891 loader configured correctly within MDMS, or that you have a problem such as a SCSI unit number collision with the GK-based jukebox control access. (Loaders such as the TL891 can be operated as a stacker or as a jukebox. The latter generally provides more flexibility. OpenVMS software uses the GK driver to access and control the jukebox.) Please check the MDMS documentation, and please check with the Compaq Customer Support Center for assistance in resolving this problem.
