- I used chg-scsi when I had a tape drive, but it did have one gotcha,
- it cannot handle a rewind correctly, nothing goes down the cable at
- all.
That's an issue with the host operating system..
chg-scsi just issues a MTREW to the tape device. If the
operating system doesn't do anything with it, well, then there'
not much it can do.. (I suppose it could issue a SCSI rewind
command directly, but it doesn't currently.)
One thing that chg-scsi seems to need, and I didn't see
in the configuration file, is a non-blocking control device for
the tape drive, in addition to the blocking device node used for
writes.. On linux, the sg* device corresponding to the tape
drive is a good one to try. On NetBSD, the `enrst?' device is
the one to use..
