This is not visible from the output I sent to the list. However, I did try
to attach the same DLT to another linux/alpha box with about the same
configuration, but being SCSI-only. In that box I have SCSI disk and the
/proc/scsi/aic7xxx/0 showed (more or less) correct statistics for the
disk but all zeroes for the DLT.

I would think then that it's the st driver in latest stable kernel
(2.2.14) that doesn't do the job.

It seems that this driver has had such problems in the past. On some intel
box I'm (still) running 2.0.38 and I have a DAT installed. The 2.0.38
records the stats for tape correctly, but some older version (I think it
was 2.0.36) recorded all writes to reads (writes all remained zero).

Regards,
  Metod
