Resolving Problems
If you encounter problems when running the drive, refer to Table 13. If the
problem is not identified in Table 13, refer to “Methods of Receiving Errors and
Messages” on page 74. The color and condition of the Status Light may also
indicate a problem. For more information, see “Status Light” on page 28.
Table 13. Troubleshooting tips
If the problem is this.... Do this....
A code displays on the
Single-character Display (SCD) and
the Status Light flashes amber.
The drive detected an error or is directing you to an informational message.
See Table 15 on page 75.
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 24).
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 30.
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 (see “Removing a SCSI Drive from an Enclosure” on page 93).
v The drive has no power. Connect power to the drive (see “Connect and
Test Power to the Drive” on page 24).
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 “TapeAlert Flags,” on page 111.
The server reported SCSI problems
(such as selection or command
time-outs, or parity errors).
See “Fixing SCSI Bus Errors” on page 86.
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 38). 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 (see “Removing a SCSI Drive from
an Enclosure” on page 93).
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.
