Loop Option
The Loop option determines what the library does after it has finished
processing the last cartridge in a sequence. As shown in Table 4-2 , the library
can either loop back to the first cartridge in the sequence and start processing
the cartridges again or stop and wait for operator intervention. (Operator
intervention typically means opening the library’s door, removing cartridges
for storage, installing new cartridges, and closing the door.)
Restart Option
The Restart option determines what the library does after it is reset or power
cycled, or after the door is opened and closed. The library can either restart at
the beginning of the cartridge sequence or resume where it left off when the
interruption occurred. As shown in Table 4-3 , the Restart option determines
what the library does next.
Before the Library Restarts... Before restarting, the library performs the
following actions:
1.
1. 1.
1. If the robot was moving a cartridge, it finishes the move. (This includes
inserting the cartridge into the tape drive if the robot was moving a
cartridge to the tape drive.)
Note: If you attempt to open the door, the library will not release the door
interlock until it has completed the move.
2. 2. 2. 2. The library performs a power-on self-test (POST). If you opened the door,
the library performs its POST after you close the door.
3.
3. 3.
3. If a cartridge is in the tape drive, the robot waits for the cartridge to be
ejected, then returns it to its original slot.
