Chapter 5: Operation
The OCP features are these:
• the magazine door
• the display, showing messages describing stacker activity (summarized in Table 5-4)
• the operator push-buttons:
– Display Mode: puts the stacker in normal, density select, or SCSI ID select mode
Note: For Silicon Graphics systems, density is controlled from the host and this
mode is not used.
– Select: selects SCSI ID and density by incrementing the current slot number on
the display to the next slot number
– Load/Unload: loads the currently selected cartridge into the tape drive; unloads
the cartridge currently in the drive; resets the stacker if a loader error has
occurred
Caution: Do not press the Load/Unload button until backup or other tape
operations are stopped at the host system. Doing so can result in operation
failure and drive unavailability.
– Open: opens the magazine door to load or unload cartridges; unloads the
cartridge currently in the tape drive, returns it to its original slot, and opens the
magazine door
Caution: The magazine door is opened only by using this button.
• key lock: enables and disables use of the OCP.
Table 5-4 lists the display messages that appear in the OCP.
