Hi -
I recently moved my internal Wangtek 5525 scsi tape drive from inside my
computer case to an external scsi encloser. The Wangtek has been working
just great the past couple of years inside my computer case and using
FreeBSD. But now it is acting up with FreeBSD since I moved it to the
external encloser.
When the Wangtek was inside my case, it was the terminating device. It
has the terminator packs in place on the unit. My CD-ROM drive is now
terminating my internal bus, and the Wangtek is terminating the external
bus (with its terminator packs). My scsi controller is a PCI Tyan S1365
with the NCR 875 chip.
As you can see from the "dmesg" output below, FreeBSD is communicating
with the Wangtek. However, not well enough to do dumps and restores.
When the tape unit was internal to my case, I had no such error messages.
I now have the Wangtek set for scsi id 4.
Are there any kernel options or scsi parameters I can tweak to get this
working ?
Any ideas ?
thanks -
Ken Whedbee
