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 and /dev/ntape when you reboot. 4. The names of the device files can be interpreted as follows: Devices in the /dev/ntape directory are "no-rewind" devices, those in /dev/tape will do a rewind on close. The device files then have the syntax, tapeX_dn where: X is the instance of the drive n is the density number For example, /dev/ntape/tape66_d1 is a device file for device 66, no-rewind using density number 1. Since all density numbers have the same parameters it does not matter which density number file is used. HP Evolution II DDS/DAT drives: UNIX, Linux and OpenVMS configuration guide 23
