We have just attached a 3590-b11 to a NT Server 4.0 Sp5. We are now able to get ADSM 3.1.2.50 talking to the 3590 but we keep on getting I/O errors in ADSM when we try to Label a Tape. We expect it to be related to the Setmode parameter that ADSM I think forwards to the 3590 which does not like it. Any help will be greatly appreciated.
