Table 39. Error codes on the single-character display (continued)
Error code Meaning
Tape drive or library-drive communication error. The tape drive determined that a failure
occurred in the tape drive's hardware or in the library-drive connection.
Degraded operation. The tape drive determined that a problem occurred which
degraded the operation of the tape drive, but it did not restrict continued use. If the
problem persists, determine whether the problem is with the drive or the media.
Note: The drive is usable, though the single-character display continues to indicate an
error and the status light flashes amber.
The tape drive needs to be cleaned. See “Locating Management functions” on page 65.
Fiber AL_PA conflict. Two drives on fiber loop have the same AL_PA.
Encryption error. Displayed when the drive detects an error that is associated with an
encryption operation.
Fiber Port offline. Displayed when the drive fiber port received a
port bypass
command from another port on the Fibre Channel network.
Fibre Channel error. No light is displayed if the drive fiber port does not detect light.
Write operation to a write protected cartridge was attempted. This action includes any
attempt to overwrite a WORM protected tape. Ensure that the tape cartridge is the
correct media type. See Appendix B, “LTO media,” on page 156.
SCD dot
If a drive dump is present while the drive is in maintenance mode, a single red dot illuminates in the lower
right corner of the SCD. To download the drive dump, see “Locating Management functions” on page 65
or “IBM Tape Diagnostic tool (ITDT)” on page 83.
The SCD dot turns OFF when you obtain a dump or update the drive firmware.
Note: If the drive dump is stored in ROM memory (SCD dot ON solid), the dump is lost when you turn OFF
the power or reset the drive.
Status light
The Status light is a light-emitting diode (LED) that provides information about the state of the drive. The
light can be green or amber, and (when lit) solid or flashing. Table 40 on page 116 lists the conditions of
the Status light and single-character display (SCD) and provides an explanation of what each condition
means.
