    Sun (Solaris 8, 9, 10) servers and workstations Fibre Channel drives Before configuring your system to support an HP LTO Ultrium drive, ensure that the drive is visible to the Sun system HBA by correctly zoning the fabric switch (if one is being used). Configuring the device files Before configuring FC-attached drives, ensure the operating system is updated with the latest recommended patches.

    You should now be able to use the drive. • Use /dev/rmt/Xcb if you require a compression rewind device file, where X is the relevant device address. • Use /dev/rmt/Xcbn when you require a compression non-rewind device. Once the device files have been created, you should confirm that your new tape drive is working properly.

  • Page 39: Verifying The Installation

    Verifying the installation Verifying the installation of the drive (UNIX) As part of the installation process, you will have installed the appropriate device driver for your UNIX system, and created device files to communicate with the tape drive. This section describes how you can verify the installation has been performed correctly. In outline, the procedure is as follows: Check the tape drive responds to a rewind command.

    The arguments follow the cvf options in the command line. Their values depend on the operating system; suggested values are given the appropriate operating system chapter.The arguments are as follows: <device file> The name of the device file for the drive. Example: /dev/rmt/c4t3d0BESTnb The name of the file to archive, prefixed with ‘./’.

  • Page 44 Fibre Channel Fibre Channel provides an inexpensive yet expandable means of quickly transferring data between workstations, mainframes, supercomputers, desktop computers, storage devices, displays and other peripherals. Although it is called Fibre Channel, its architecture represents neither a channel nor a real network topology. It allows for an active intelligent interconnection scheme, called a fabric, to connect devices.
