NW 6.5.5, tape backup using SBCON has been working daily, flawlessly for
about a year (the age of the hardware). For the past 4 days, with no
hardware or software change, the backups have failed, as follows: "SMSDI
unable to write to the media. Check if the media is write protected.
TSA error code: fffcffce." The tapes are not write protected and I
think it's fair to assume that theses tapes have all failed
simultaneously. After the message appears, the program appears to be
trying still to backup the server - the yellow light is on and the tape
is clearly making noises consistent with when it is recording. A check
of the Knowledgebase was unavailing.
