When the autoloader is operating in Sequential mode, its internal firmware
instructs the robot to move cartridges sequentially between the cartridge slots
and the tape drive. No application software is required to support cartridge
movement.
Sequential operation occurs as follows: The robot picks the cartridge from slot
1 and places it in the tape drive. The robot waits until the tape drive ejects the
cartridge, then returns the cartridge to its original slot. The robot repeats these
steps for the next cartridge until it has processed all of the cartridges in the
magazine. The robot either returns to the first cartridge and begins the
process again or stops, depending on the setting of the Loop option (described
in Table 3-3 ).
To customize how Sequential mode works, you can set the Loop, Restart, and
Next Cart options. These options are not affected by a reset or power cycle.
Table 3-3 describes the sequential mode options.
Table 3-3 Sequential mode options
Option Description
Loop The Loop option determines what the autoloader does after it has finished processing the
last cartridge in the magazine. The settings for the Loop option are as follows:
On – The autoloader returns to cartridge 1 and starts processing the cartridges again.
Off – The autoloader stops processing cartridges and waits for operator intervention.
(Operator intervention typically means removing the autoloader’s magazine, replacing
cartridges, and re-inserting the magazine.)
Restart The Restart option determines where the autoloader restarts after it is reset or
power-cycled, or after the magazine is removed and replaced. The settings for the Restart
option are as follows:
On – The autoloader restarts at slot 1.
Off – The autoloader resumes where it left off.
Before the autoloader restarts, the following actions occur:
!
The autoloader performs a power-on self-test (POST).
!
If the robot was moving a cartridge, it finishes the move. (This includes inserting the
cartridge into the drive if the robot was moving a cartridge to the drive.)
Note: If you attempted to remove the magazine, the autoloader does not release the
magazine’s solenoid until it has completed the move.
!
If a cartridge was in the drive, the robot waits for the drive to eject the cartridge, then
reseats the cartridge in the drive. The robot then checks for cartridges in the magazine
and returns the cartridge to its original slot.
Next Cart The Next Cart option allows you to interrupt sequential processing and specify that the next
cartridge the autoloader selects is the cartridge in slot 1. Whenever you want to resume
sequential processing from the first cartridge, select Next Cart from the Sequential Options
Menu.
