NOTE

Figure 2-1

Using Tape Cartridges

Labeling Tape Cartridges

Make it a practice to use bar code labels on your tape cartridges. Your host software may need to keep track of the following information and the associated bar code:

???date of format or initialization

???cartridge owner (such as group or department)

???storage purpose (such as backup, old version of operating system)

If the host software does not keep track of this information, create a method of doing so.

Slide the label into the slot on the face of the cartridge as illustrated in Figure 2-1.

If bar code labels are not used and the ???Barcode On/Off??? configuration is set to ???Off,??? the Inventory Check test performance can be significantly impacted. This test runs when the library is powered on and whenever the front access door is opened.

See Appendix A for information about ordering additional bar code labels.

Inserting/Removing Cartridges with Software

If the software package requires that cartridges be inserted and removed using the software, check the software documentation before proceeding.

Label all cartridges before inserting them into the magazines. (See ???Labeling Tape Cartridges??? on page 2-4.)

The bar codes and storage slot locations are stored in library memory when the door is closed and the Inventory Check test is automatically run.

Keeping Cartridges in the Magazine

To prevent cartridges from sliding out of the bulk load magazines when inserting them into the library:

???Do not use excessive force when inserting the magazines. This can cause the magazine ???latching??? mechanisms to fail.

???Do not insert magazines when the library power is turned off. During normal library operation, the cartridge release button on top of the magazine is pushed down by a special mechanism inside the library. This ???unlocks??? the cartridges, allowing them to be inserted and removed from the storage slots as needed. When the control panel RELEASE DOOR option is enabled, the button on top of the magazine is released, which ???relocks??? the cartridges into the magazine slots. During a power failure, however, this button is not released, and cartridges can slide out of their storage slots if a magazine is inserted or removed from the library. (If no magazines are in a library, the special mechanism defaults to the position that keeps cartridges locked into the magazine storage slot.)

autochanger. See tape library.

autochanger controller. The part of the library that controls the sending and receiving of SCSI commands and controls the picker.

bulk load magazine. See magazine.

cartridge . A plastic enclosure that contains the digital linear tape. The tape is never removed from the cartridge.

cleaning cartridge. A special tape cartridge that is used to clean digital linear tape drives.

control panel. The part of the library that is used to manage and display library functions.

digital linear tape. Digital linear tape (DLT) drives read and write data to digital linear tape in straight tracks that run the full length of the tape. The read/write head moves vertically to read from or write to the tracks on the tape.

driver. A program that allows the operating system to communicate with a peripheral device.

element . A SCSI term for any one of the autochanger components-- drive, storage slots, or picker.

jukebox. See tape library.

library. See tape library.

LAN. Local Area Network. A group of computers and peripherals physically connected so users can share hardware and software resources.

magazine. A removable part of the library used to insert, remove, and store tape cartridges in the library.

peripheral device . A product used in conjunction with a computer, that is physically separate but that is under the computer???s control. It is usually connected to the computer by cables or wires. Printers, disk drives, scanners, libraries, and modems are examples of peripheral devices.

picker. See transport mechanism.

rack. A cabinet-like product used to house one or more computer peripherals. Computer peripherals are mounted to special brackets or rack slides which allow the peripherals to be installed into the rack.

rack slides. Expandable mechanical devices that are mounted to a computer peripheral and allow the peripheral to be installed into a rack which can house multiple computer peripheral devices. The rack slides allow the peripheral to be extended out of the rack for service.

rails. The vertical slotted metal pieces at the front and back of a rack used to mount the rack slides to the rack.

SCSI. An acronym for the Small Computer Systems Interface.

slides. See rack slides.

storage slot. An area of the magazine that holds cartridges when the cartridges are not in the drive.

swap. A motion that occurs when the transport mechanism replaces one tape cartridge in the drive with another, returning the first to its storage slot.

Glossary-2

Glossary

tape library. A term synonymous with jukebox or autochanger. This type of tape storage device is often referred to as a ???jukebox??? because when a file is requested, the tape cartridge containing the file is found, inserted into the drive, and the requested information is sent to the host computer system. This is similar to the way a musical jukebox finds a record and moves it to the turntable when a song is requested.

terminator. A resistor array device used for electrically terminating a SCSI bus. A SCSI bus must be terminated at its two physical ends. A peripheral device uses a terminator only if it is at the end of the bus.

transport mechanism. The part of the library that transports tape cartridges to and from storage slots and the drive.

UPS . Uninterruptible Power Supply. A product that is used to supply power to computer systems when there is a power failure.

write-protect. A feature that prevents data from being written to a tape. A write protect tab is located on the tape cartridge to enable write-protection of the tape.
