3. Versions of Tru64 before v5.1B-2 only: Rebuild the kernel by running:
/sbin/ddr_config -c /etc/ddr.dbase
then reboot the system with the tape drive attached. The device files for the drive will be
generated in
/dev/tape
4. The names of the device files can be interpreted as follows:
Devices in the
/dev/ntape
rewind on close.
The device files then have the syntax,
where:
is the instance of the drive
X
is the density number
n
For example,
/dev/ntape/tape66_d1
number 1. Since all density numbers have the same parameters it does not matter which density
number file is used.
