Also, let's see the relevant > dmesg output again. The drive worked fine on two other FreeBSD 4.1 machines. Identical hardware. Similar, but not quite identical OS versions. We just shut down the machine it was on, shut down the destination machine, moved the cable from one machine to the other, then powered everybody back up. Obviously, we should have considered doing a remote dump instead of moving the tape drive... mt rewind does the same thing as mt status; a kernel message (on the console and in dmesg) stating: ``(sa0:ahc0:0:5:0): unable to rewind after test read'' as well as a message on the terminal where the command was run saying ``mt: /dev/nrsa0: Device not configured''. I removed and recreated the *sa* devices in /dev with no effect. Relevant dmesg output is: ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xdc00-0xdcff mem +0xedfff000-0xedffffff irq 11 at device 13.0 on pci0 aic7880: Wide Channel A, SCSI Id=7, 16/255 SCBs sa0 at ahc0 bus 0 target 5 lun 0 sa0: <HP HP35470A 1009> Removable Sequential Access SCSI-2 device sa0: 5.000MB/s transfers (5.000MHz, offset 8) Kenneth To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
