AIX Device Drivers and Switching Data Compression
After you use SMIT to install the tape drive, device files are created for accessing the tape drive. Typ-
ical examples are:
/dev/rmt0
/dev/rmt0.4
With the configuration information provided here, devices rmt0, rmt0.1, rmt0.2, and rmt0.3 cause
the drive to write in compressed mode. Using devices rmt0.4, rmt0.5, rmt0.6, and rmt0.7 causes the
drive to write with compression disabled.
/dev/rmt0.1
/dev/rmt0.
/dev/rmt0.5
/dev/rmt/0.6
