Table 5-1. Diagnostic and Maintenance Function Codes and Descriptions (continued) Function Code F - Write Performance Test Causes the tape drive to perform tests to ensure that the drive can read from and write to tape. This diagnostic performs fewer tests than the Run Tape Drive Diagnostics test (Function Code 1). The tape drive takes approximately 3 minutes to run the test. The Fast Read/Write Test is not as comprehensive a test and is not recommended for isolating errors between the drive and the media. Attention: Data on the suspect tape will be overwritten. 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 F appears in the single-character display. If you cycle past F , 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, C flashes.

The drive acknowledges the request by slowing the length of time that the currently displayed character flashes on the single-character display (from twice per second to once per second.)

The tape drive then rewinds, unloads the cartridge, and exits maintenance mode. v To halt the diagnostic immediately and terminate the test that is running, press the eject button twice. The tape drive rewinds, unloads the cartridge, and exits maintenance mode. Chapter 5. Troubleshooting 5-5

Function Code F - Write Performance Test
Causes the tape drive to perform tests to ensure that the drive can read from and write to tape. This diagnostic
performs fewer tests than the Run Tape Drive Diagnostics test (Function Code 1). The tape drive takes
approximately 3 minutes to run the test. The Fast Read/Write Test is not as comprehensive a test and is not
recommended for isolating errors between the drive and the media.
Attention:
Data on the suspect tape will be overwritten.

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.
