We have an EXAbyte EXB-10e connected to an Alpha 3000/400 running 3.2C. We
are getting this problem regularly. During the dumps we receive an IO
error message, then the tape unit is unavailable??
Any clues. Here is a transcript of the dump log, a "file /dev/*mt*"
subsequently, a "file /dev/*mt*" after a power cycle of the drive and
errors from uerf.
