50 LTO Ultrium 8-Slot Autoloader User’s Guide
If the cartridges are properly installed, the autoloader is ready for
operation after performing either a POST or a self-test. If the autoloader
encounters a problem during a POST or the self-test, it reports an error on
the LCD.
Initial Element
Status Time
1
When an initiator sends an INITIALIZE ELEMENT STATUS (IES) command,
the autoloader checks each cartridge slot for the presence of cartridge.
The autoloader requires 21 seconds to perform an
IES command.
Move Complete
Time
1
Move complete time is measured from the time the autoloader receives a
Move command to the time it returns status to the initiator indicating that
the move is complete. The average time required for the autoloader to
move the cartridge slot into position in front of the tape drive and either
insert or remove the cartridge from the tape drive is less than 45 seconds.
Reliability 1 The mean cycles between failures (MCBF) for the autoloader's robot is
250,000 cycles. This value does not include failures attributable to the tape
drive or cartridges.
During one full cycle, the cartridge loader completes the following
actions:
1 Picks the cartridge from a cartridge slot.
2 Places the cartridge in the tape drive.
3 Removes the cartridge from the tape drive.
4 Replaces the cartridge in the cartridge slot.
