Checking and Setting the Device ID
Using the Operator Buttons to Check or Set the Device ID
The device ID of a tape drive is stored in nonvolatile random-access memory
(NVRAM). You can check or set the device ID using the operator buttons on the drive
or ACL front panel. Power must be applied to the drive before you can check or set
the device ID. The procedure is the same for drives with and without ACLs. If you
want to familiarize yourself with the drive and ACL front-panel controls before
beginning this procedure, review Section 4, Operating the Cartridge Tape Drive
and ACL.
Use Steps 1 through 8 of the following procedure to check the device ID. Use the
entire procedure if you want to change the device ID.
To end the procedure at any time, press SHIFT + RESET and press RESET again to
initiate the self-test and restart the drive. After restart, an asterisk (*) should appear on
the message panel of the drive or ACL front panel.
1. If the tape drive has an ACL, unload any loaded cartridge by pressing the RESET
and then the UNLOAD button. Then press RESET again until an asterisk (*)
appears on the message panel. Remove the cartridge magazine and close the
door.
If the tape drive does not have an ACL, unload any cartridge currently loaded in
the drive by pressing the RESET and then the UNLOAD button.
2. Press the TEST and UNLOAD buttons simultaneously and hold for at least three
seconds. This places the drive in the diagnostic mode. The following appears on
the message panel:
DIAGMODE
3. Press the START button to begin the process. The message panel shows:
SETTING
4. Press START again to select configuration mode. The message panel shows:

5. Press the TEST button to take the controller offline. The message panel shows:
CTLR OFL...
PUSH STR
6. Press START to enter the configuration mode. The message panel shows:

7. Press TEST to begin the device ID set mode. This message on the message
panel identifies the device ID mode:
1:TADDR
8. Press TEST to display the current device ID on the message panel.
