Hi, I hope you can help me, one of our customers sets 4 x 2108-R03 Router for the connection to one IBM 3584-L32 Library. 8 x 3580 LTO LVD TAPE drives are attached there. The operating system is Windows2000 advanced server with SP1 . The application is TSM 4.1.3 Attach at every Router 1-4, 2 LVD Tape drives, at each. At the first Router is attached for the Changer/Library. and 2 Tapes. After every restart of the server, the Changer/Library change from LUN ID 2 or 3 or 4. All Router are switchted in one Zoon with the TSM Server FC-Adapter. 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 is a LP8000N SW. The Switch is a IBM 2109-S16 with firmware .37. What can I do? Is there any on who can help me? Or is there on who has another constellation with more as two Routers? Do you have a valid konfiguration of as Router who works fine? thanks for reply, Norbert with kind regards / mit freundlichen Gruessen Norbert K. Martin Norbert K.
