Function Code 3: Create FMR Tape Function Code 3 copies the drive's field microcode replacement (FMR) data to a scratch data cartridge. Attention For this function, insert only a scratch (blank) data cartridge or a cartridge that may be overwritten. During the test, the drive overwrites the data on the cartridge. Attention: Customers should only attempt this step when requested by IBM service. 1. Place the drive in maintenance mode. For instructions, see "Entering Maintenance Mode" on page 15. 2. Press the Unload Button once per second until 3 appears in the SCD. (If you cycle past the desired code, press the Unload Button once per second until the code reappears.) 3. Press and hold the Unload Button for three or more seconds, then release it to select the function. The SCD changes to a flashing C . 4. Insert a scratch (blank) data cartridge that is not write protected (or the tape drive exits maintenance mode). The SCD changes to a flashing 3 . The tape drive copies the FMR data to the scratch data cartridge. Note: If you inserted an invalid or write-protected tape cartridge, error code 7 appears in the SCD. The tape drive unloads the cartridge and exits maintenance mode. v If the tape drive creates the FMR tape successfully, it rewinds and unloads the new tape, exits maintenance mode, and the tape is ready to use. v If the tape drive fails to create the FMR tape, it displays an error code. To determine the error, see Table 9 on page 45. The tape drive then unloads the FMR tape, exits maintenance mode. Function Code 4: Force a Drive Dump Function Code 8 performs a dump of data collected by the drive (this process is also known as saving a microcode trace). Attention: Customers should only attempt this step when requested by IBM service. 1. Place the drive in maintenance mode. For instructions, see "Entering Maintenance Mode" on page 15. 2. Press the Unload Button once per second until 8 appears in the SCD. (If you cycle past the desired code, press the Unload Button once per second until the code reappears.) 18 IBM 400/800GB LTO3 Tape Drive User's Guide
