I am trying to use HP Colorado T8000es with Adaptec AHA-1542CF host adapter under FreeBSD 2.1. I were not able to make the drive do *anything*, even a status printout (mt -f /dev/rst0 status). When the machine boots, the drive flashes its light and I can hear the tape winding back and forth. But that about all activity that goes on. /var/log/messages: /kernel: (aha0:4:0): "HP T4000s 1.06" type 1 removable SCSI 2 /kernel: st0(aha0:4:0): Sequential-Access density code 0x45, drive empty But when I am trying to use the mt command, I get this: /kernel: st0(aha0:4:0): timed out /kernel: st0(aha0:4:0): timed out AGAIN Someone suggested that termination might be a problem. There are no internal devices in the computer, so the adapter is serving the tape drive only. I have installed a passive external terminator that came with the drive on one of the SCSI connectors on the drive. According to the AHA-1542C series manual, host adapter termination should be enabled through the SCSISelect program if there are only external devices present (adapter at the end of the cable). I checked switches -- termination is enabled. In case anyone knows the switch settings for 1542, mine are: all off, except switch 5. When I use the mt command, the SCSI activity LED on the adapter does not flash. One thing though: the SCSI cable I am using is about 3 feet long. Could that be the cause? Can anyone help me with this? I have no idea what is wrong. I tried to connect a Wangtek drive a few weeks ago and had the same problem. Thanks a lot in advance, Andrew Prihodko ------ prihodko@fas.harvard.edu
