Rebuild the kernel by running /sbin/ddr_config, then reboot the system
with the tape drive attached. The device files for the Ultrium drive will be
generated in /dev/rmt when you reboot.
4 The names of the device files can be interpreted as follows:
[n]rmtX D
where:
Code Meaning
n No rewind
X Instance number assigned to the drive by the operating system
(0 is the first, 1 is the second, and so on)
h Compression on (high density)
l Compression off (low density)
For example, /dev/rmt/nrmt0h is a device file for the first device, which
is a high-density, no-rewind device.
Once the device files have been created, you should confirm that your new tape
drive is working properly. See
