FWIW, I had a very similar support question some time ago, and the problem of the customer went away after upgrading the firmware of the RAID controller. As the original poster is from germany, I quote something from the original answer: ---- Der Raid-Controller der Firma Infortrend Typ IFT-3102U muss um mit einem Adaptec 2940 UW Controller zusammenarbeiten mindesten die Firmwareversion 1.31 besitzen, sonst führt das SCSI-Target Inquiry zum SCSI-BUS hang. Das Update der Firmware ist via E-Mail unter support@infortrend.com zu bestellen! ---- He also had the problem that the Inquiry led to a SCSI bus hang. > Doug Ledford hope it helps, Hubert
