The operating system is Windows2000 advanced server with SP1 . The application is TSM 4.1.3 You attach at every Router 1-4 per 2 LVD Tape drives. At the first Router is attached for the Changer/Library.an 2 Tapes. After every restart of the server the Changer/Library change from LUN ID 2 over 3 or 4. The Library doesn't have to be left possibly on a LUN ID constantly so that TSM server 4.1.3 can work with that. The RSM under WIN2000 is disabled. As server adapter a LP8000N SW is used by emu lex.
