on our alpha 2100 running DU4.0a, out tz87 DLT tape unit is not
recognized after a crash( do to failed AC). The tape unit was
fine before the crash. It is seen at the hardware level, but
not the logical level.
the error is:
mt stat
/dev/nrmt0h: No such device or address
but,
ls -la /dev/rmt*
crw-rw-rw- 1 root system 27, 2 Oct 1 11:17 /dev/rmt0h

So it looks like its there from a SCSI point of view. the edt looks
the same on systems that do have working tape units.
I have rm the dev file and run a MAKEDEV tms0, but no luck.
the dlt unit works ok on an Nt box.
anyone have suggestions for getting the dev file corrected so we
can use the tape unit?
thanks,
Jeff
