However, if termination on the controller is always on, then it should work when there are devices attached to only one of the two SCSI onboard connectors. OTOH, if termination is always off, then it should work when there are terminated device chains attached to both onboard SCSI connectors... or am I wrong? > The dump is only useful with an understanding of the corresponding > SCSI Select settings.

Well, I did the following tests (logs attached): narrow20.log Wide neg. disabled, 20 MB/s (all targets) narrow10.log Wide neg. disabled, 10 MB/s (all targets) narrow5.log Wide neg. disabled, 5 MB/s (all targets) wide40dlt10.log Wide neg. enabled, 40 MB/s, except tgt#5 (narrow, 10 MB/s) wide40.log Wide neg. enabled, 40 MB/s (all targets) wide40termOFF.log Like wide40, but setting term. to "High OFF/Low OFF" All tests but the last one were performed with the other termination setting: "High ON/Low Auto". Notice the "narrow5" test: all targets are set to 5 MB/s (5 MHz sync). Despite of that, the speed negotiated with the DLT unit is 10 MB/s! In all tests a simple "mt status" hangs the SCSI bus or at least the DLT unit, because the command "camcontrol reset 2" does not seem to have any effect on the DLT. Thank very much for your help, especially after it seems clear that ahc(4) is not accountable for this problem :-) Regards, JMA -- ****** Jose M.
