Hi, I have a Overland NEO2000 tape library with 2 HP Storageworks Ultrium-3 drives installed. The Problem is that the drive(s) regularly get "unreachable". I have two other libraries of the same type with LTO-1 and LTO-2 drives, which are working perfect. First I thought it's a hardware problem, so I changed everything - The HBA's, the Library, the tapes, the Fibre-channel conversion card, all cables, even the server. I even switched from debian etch to a supported operating system (RedHat AS4). No luck at all. Can somebody check the output of the log below and tell me what is happening there exactly ? I did a lot of research but could not find anything regarding this issue. Many thanks, Florian May 26 21:35:37 mhbackupu01 kernel: st2: Error 20000 (sugg. bt 0x0, driver bt 0x0, host bt 0x2).
