Performing the Final Steps
Performing the Final Steps
When the tape library and all tape drives are configured, perform these final steps
before testing the tape library:
1. Power off the tape library.
2. Open the right side door.
For CT9841FC-1 tape drives:
a. Insert the single connector end of the Y cable into all drives.
b. Install the client Fibre Channel cables.
c. Check that all tape drive power switches are in the ON (1) position.
3. Power on the tape library. An initialization sequence (described next) begins.
Initialization Sequence
An IPL occurs when the tape library powers on or the RESET button is pressed. The
IPL process consists of functional firmware loading.
The MPC card directs the initialization process, which consists of the following:
•
Initialization and calibration of robotic mechanisms
•
Calibration of the vision system
•
Motion testing
•
Hand assembly testing
•
An audit of tape cartridges within the tape library
•
Audit of reserved cells
These steps are explained in the next sections.
Initialize and Calibrate Mechanisms
Robotic mechanism parameters are loaded into processor memory and calibration
routines are executed. The initialization process requires a maximum of five minutes.
Monitored in this sequence are:
•
Reach save position. The reach mechanism fully retracts, and the reach save
sensor must be detected before any theta or Z motion is initiated. This prevents
possible damage to the hard assembly or to a tape cartridge.
•
Z motor calibration. The Z mechanism moves from the end-stop to end-stop. The
distance and time for this motion is compared against the mechanism parameters
within the firmware.
