GLOSSARY
I
Initiator A SCSI device containing application clients that originate device service requests to be processed in a device server. The host typically acts as the initiator of commands.
L
LED Light Emitting Diode. The indicators on the front panel of the tape drive.
Load The process of inserting a cartridge into the tape drive. The tape drive automatically loads the tape into the tape path.
Low Voltage Differential (LVD) A differential SCSI interface that allows bus lengths up to 12 meters, transfer rates up to 160 MB/sec., and allows
M
msec Millisecond;
Mean Time Between Failures (MTBF) A quantitative measure used to specify the reliability of a tape drive’s mechanics and electronics as a whole under specific environmental conditions, cleanings, and duty cycle.
Megabyte One million bytes.
N
Noise Any kind of magnetic or electric interference detected by the electronics.
O
OverScan Operation (OSO) The VXA technique for reading data packets independently of track shape or geometry. By reading packets with multiple scans, OSO ensures that each packet is read at least once.
P
Packet The basic VXA format structure that includes data, ECC, and address and synchronization information.
Partition A
Peripheral Device Any device attached externally to a computer as an optional device, such as tape drives, printers, scanners, and so forth.
Power Cycle (1) Turn the tape drive off, wait for 10 seconds, then turn the tape drive back on. Wait for the tape drive to go through its
(2)If you are required to power cycle the tape drive due to overheating, allow it to cool for several minutes before turning it back on (see “LED 4 is Flashing Orange” on page 26 for additional information).
