Chapter 6. Resolving Problems
If you encounter problems when running the IBM TotalStorage LTO Ultrium 2 Tape
Drive, refer to Table 13. If the problem is not identified in Table 13, refer to “Methods
of Receiving Errors and Messages” on page 66. 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 15 on page 67.
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 6. Connect and Test Power to the Tape
Drive” on page 27). 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 83 or “Removing a Fibre Channel Tape Drive from an Enclosure” on
page 84).
v The tape drive has no power. Connect power to the tape drive (see “Step
6. Connect and Test Power to the Tape Drive” on page 27).
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 85).
The server received TapeAlert flags. See Appendix B, “TapeAlert Flags” on page 97.
The server reported SCSI problems
(such as selection or command
time-outs, or parity errors).
See “Fixing SCSI Bus Errors” on page 77.
The server reported Fibre Channel
problems.
See “Fixing Fibre Channel Errors” on page 79.
The Fibre Channel drive indicates no
Fibre Channel light, or has light but
cannot communicate.
See “Fixing Fibre Channel Errors” on page 79.
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 in Table 9 on page 36). If the test runs successfully but
the problem persists, refer to your library’s service documentation.
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 83 or “Removing a Fibre Channel
Tape Drive from an Enclosure” on page 84).
