Introduction Before you install your tape drive log on to the HP web site, www.hp.com, and download the latest hardware enablement patch bundle for your operating system. This ensures that you will have the correct device driver for your tape drive. Determining the SCSI ID Before you configure your system to support your new HP Ultrium drive, you need to determine what SCS

To create device files using mksf: NOTE: This method is not recommended. 1. Run insf as follows: % /sbin/insf -C tape 2. Create the device files for the devices using the mksf command as follows: % /sbin/mksf -d stape -I [-n] [-u] /dev/rmt/X where: Argument Description -d stape Specifies the SCSI tape driver -I Specifies the tape drive’s hardware address via the instance of the SCSI tape driver. The first instance is 0, the second 1, and so on. [-n] Specifies no rewi

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/tape and / dev/ntape when you reboot. 3. 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 wil
