Autoloader Self-Test Times
Each time the autoloader is powered on, it performs a power-on self-test (POST). POST includes a
self-test of the control electronics, initialization of the mechanical components, and a cartridge
inventory. The POST time is measured from the time the autoloader is powered on until the autoloader
indicates Ready status. The maximum time required for POST is about 150 seconds.
The autoloader also performs a self-t est when you select Library Test from the operator panel or in
response to a SEND DIAGNOSTICS SCSI command. The maximum time required for this self-test is
9 seconds.
If the cartridges are properly installed, the autoloader is ready for operation after performing either
POST or its self-test. If the autoloader encounters a problem during POST or the self-test, it reports an
error on the LCD.
Initial Element Status Time
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
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 typically is less than 45 seconds.
Reliability
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.
