Chapter 5. Resolving problems
If you encounter problems when running the LTO-2 Tape Drive, refer to Table 6. If
the problem is not identified in Table 6, refer to “Methods of receiving errors and
messages”. The color and condition of the status light may also indicate a problem.
For more information, see “Status light” on page 32.

If the problem is this.... Do this....
A code displays on the
single-character display and the
status light flashes amber. The tape drive detected an error or is directing you to an informational
message. See Table 8 on page 49.
The status light or single-character
display never turns on. The tape drive has no power. Check the power at the power source. Connect
power to the tape drive (see “Step 4. Connect and test power to the tape
drive” on page 11). If the problem persists, replace the tape drive.
The tape 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
tape 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 34.
v
The tape cartridge may be defective. Insert another tape cartridge. If the
problem exists for multiple cartridges, the tape drive is defective. Replace
the tape drive (see “Removing a SCSI tape drive from an enclosure” on
page 57 ).
v The tape drive has no power. Connect power to the tape drive (see “Step
4. Connect and test power to the tape drive” on page 11).
The tape 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 tape drive, then turn it
back on (note that the mid-tape recovery could take up to 5 minutes to
complete). If the cartridge still does not eject, manually remove it (see
“Manually removing a tape cartridge” on page 58).
The server received TapeAlert flags. See Appendix B, “TapeAlert flags”, on page 71.
The server reported SCSI problems
(such as selection or command
time-outs, or parity errors). See “Fixing SCSI bus errors” on page 53.
Codes display on the single-character
display, but the status light does not
turn on. The tape drive is defective. Replace the tape drive (see “Removing a SCSI
tape drive from an enclosure” on page 57).
The tape drive does not respond to
server commands. Press and hold the unload button on the drive for 10 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 7 on page 48 as a guide for identifying error codes and message codes
reported by the LTO-2, its enclosure (if applicable), or the server.
