We have a strange problem which just started on our M/120 system.
The system includes a QIC120 tape drive, which we have been using
for archiving of various data. We do this by using the following
sequence:
mt -f /dev/rmt/Q120n-0 fsf [#]
tar cvf /dev/rmt/Q120n-0 [file]
mt rewind
Up until this Sunday, everything went OK. Of course, using this
method one must keep careful track of what is on the tape, both
contents and size of each record. Now the problem. We tried to
use this last weekend on an existing archive, and we got a total
failure. The tape comes to the end of the record, and then just
hangs. This doesn't do the same thing on our RX2030 systems. We
can make multiple records on the M/120 without rewinding, but as
soon as the tape is rewind, the logical end of the tape is lost.
However, this tape is still readable/writable on a RX2030, but there
seems to be two end of record marks at the end of the last record
created by the M/120.
Any help is greatly appreciated, since we really need to be able to
use this facility.
