DEC tape drive via SunOS 4.1.3
Posted on 1997-02-22
We have a Sun 4/280 running SunOS 4.1.3 with a DEC TLZ06 4mm drive on a SCSI bus which we use for backups. The default mode for this drive is uncompressed mode. How do we set
the drive to run in compressed mode?
The drive documentation, for Ultrix and VMS, states that the mode is determined based on the entry used in /dev, such as /dev/rmt?1 for uncompressed and /dev/rmt?h for compressed. We don't have comparable device names on the Sun, and the only entries I'm aware of that access the drive do so in uncompressed mode.
