Table 7. Troubleshooting tips (continued) If the problem is this.... Do this.... The Status Light or SCD never turns on. The drive has no power. Check the power at the power source. Connect power to the drive (see "Connect and Test Power to the Drive" on page 9). If the problem persists, replace the drive. The drive will not load a tape cartridge. One of the following has occurred: v A tape cartridge is already inserted. To remove the cartridge, press the Unload Button. If the cartridge does not eject, turn off the power to the drive, then turn it back on. After the Status Light becomes solid green, press the Unload Button to eject the cartridge. v The tape cartridge was inserted incorrectly. To properly insert a cartridge, see "Inserting a Tape Cartridge" on page 13. v The tape cartridge may be defective. Insert another tape cartridge. If the problem exists for multiple cartridges, the drive is defective. Replace the drive. v The drive has no power. Connect power to the drive (see "Connect and Test Power to the Drive" on page 9). The drive will not unload the tape cartridge. The tape cartridge is stuck or is broken. Press the Unload Button. If the cartridge does not eject, turn off the power to the drive, then turn it back on (note that the mid-tape recovery could take up to ten minutes to complete). If the cartridge still does not eject, contact IBM Support. The server received TapeAlert flags. See Appendix A. See Appendix A, "TapeAlert Flags," on page 65. The server reported SCSI problems (such as selection or command time-outs, or parity errors). See "Fixing SCSI Bus Errors" on page 50. The library reported an LDI or RS-422 communication problem with the drive. The LDI or RS-422 circuitry may be defective. Run the LDI or RS-422 wrap test ("Function Code 7: Run RS-422 Wrap Test" on page 20). If the test runs successfully but the problem persists, refer to your library's service documentation. Codes display on the SCD, but the Status Light does not turn on. The drive is defective. Replace the drive. The drive does not respond to server commands. Press and hold the Unload Button on the drive for ten seconds to force a drive dump. The drive will save the dump and then reboot to allow communication to the drive to occur. Do not cycle power, as this will erase the contents of the dump. Methods of Receiving Errors and Messages Use Table 8 as a guide for identifying error codes and message codes reported by the drive, its enclosure (if applicable), or the server. Note: The codes on the Single-character Display (SCD) have different meanings, depending on whether they display during normal operations or while the drive is in maintenance mode. Codes that occur during normal operations are defined in Table 9 on page 45. Codes that occur while in maintenance mode are defined in "Diagnostic and Maintenance Functions" on page 15. Table 8. Methods of receiving errors and messages If the error or message was presented by.... Do this.... The enclosure's display (if the drive Refer to the documentation for the enclosure. is enclosed in a library or autoloader) 44 IBM 400/800GB LTO3 Tape Drive User's Guide
