  • Page 26: Figure 2-4 Connecting A Scsi Cable (Tape Drive Is Last Device On The Bus)

    HAPTER NSTALLATION Install an LVD or LVD/SE multimode terminator at the physical end of the SCSI bus. If the cable provided with your adapter has a built-in terminator, do not add another terminator to the bus. Note: If there are additional devices on the SCSI bus, ensure that only the device at the physical end of the bus is terminated.

  • Page 27: Figure 2-5 Screw Mounting Configurations (Internal Model)

    Using the screws provided with the tape drive, secure the tape drive in the drive bay using one of the screw mounting combinations (see To avoid damaging the tape drive, follow these precautions: Caution Use only the M3 5mm. Ensure that the chassis is not distorted. (Alignment to the horizontal or vertical plane should not exceed ±10°.) Ensure that no objects (screw heads, cables, or adjacent devices) are pressing against the frame.

  • Page 36: Using Vxatape Cartridges

    TAPE ARTRIDGES The tape drive uses data-quality VXAtape data cartridges, in various lengths, available from Tandberg Data and authorized sources. These cartridges do not require formatting or other media conditioning before use. See page 49 for compatibility and capacity information for VXAtape cartridges. See page 23 for storage guidelines.

  • Page 37: Storing The Cartridges

    TORING THE If VXAtape cartridges are stored properly, you can expect to successfully recover data from them for 30 years. Be aware that the 30-year storage life is for an archival tape, not a tape being used for daily backups. As a general rule, use a new (or relatively unused) cartridge to store any critical data you may need to recover many years from now.

  • Page 38: Using A Cleaning Cartridge

    Do not use any cleaning method other than the VXAtape Cleaning Cartridge (or a Caution cleaning cartridge approved by Tandberg Data for use with VXA tape drives). Using other cleaning methods may void the tape drive’s warranty. Do not rewind and reuse the material in a cleaning cartridge. Reuse may redistribute contaminants previously removed from the tape path.

  • Page 41: Tape Drive Will Not Eject A Cartridge

    RIVE If the tape drive does not eject a cartridge when you press the eject button, do the following: Use your backup application to eject the cartridge. To protect against accidental tape ejection during a backup or restore operation, many applications prevent using the tape drive’s eject button for media removal.

It includes the following topics: Communication interface versus command protocol SCSI communication interface SCSI interface requirements SCSI command protocol OMMUNICATION NTERFACE VERSUS When a device is connected to a host computer, their interaction is accomplished via a communication interface (for example, a parallel SCSI bus).

  • Page 52: Scsi Communication Interface

    HAPTER OMMUNICATION NTERFACE AND The format and content of the information carried over the communication interface, as well as how each device uses and responds to the information, is governed by a command protocol. The command protocol determines how the host (or initiator) interacts with the target device (for example, the tape drive) by issuing commands to control its operation, transferring data, and responding to status information.
