Table 5-1. Diagnostic and Maintenance Function Codes and Descriptions (continued) Function Code 4 - Force a Dump of Vital Data to Tape Drive Memory Causes the tape drive to perform a collection (or dump) of vital technical data and save it to drive memory. (A drive dump is also known as a save of the firmware trace.) Notice: When an error code is displayed in maintenance mode, the tape drive also displays a dot to remind you that a dump already exists. If you perform Function Code 4, it will overwrite the dump and cause the error information to be lost. 1. Ensure that there is no cartridge in the drive. 2. Press the eject button three times within an interval of 2 seconds. The fault LED becomes solid amber, which means that the drive is in maintenance mode. 3. Press the eject button once per second until 8 appears in the single-character display. If you cycle past 8 , continue to press the eject button until it reappears. 4. To select the function, press and hold the eject button for 3 seconds. After you select the function, 8 displays, followed by 0 . The single-character display then goes blank, and the tape drive exits maintenance mode. You can also perform this operation when the tape drive is in normal operating mode. Simply press and hold the eject button for 10 seconds.
