IBM Ultrium Gen 6, Installation And User Manual

Page: 36 / 118

Appendix C, “Error codes and messages,” on page 63 lists the codes for error
conditions and informational messages. If multiple errors occur, the code with the
highest priority (represented by the lowest number) displays first. When the error
is corrected, the code with the next highest priority displays, and so on until no
errors remain.
“Diagnostic and maintenance functions” on page 25 lists the single-character codes
that represent diagnostic or maintenance functions. To initiate a function the unit
must be in Maintenance mode.
The SCD is blank during normal operation.
SCD dot
If a drive dump is present while the drive is in Maintenance mode, a single dot
illuminates in the lower right corner of the SCD (see
8
). To copy the dump, see
“Function code 5: Copy drive dump” on page 31.
The SCD dot is on solid if the dump is in RAM memory. The SCD dot flashes if
the dump is in FLASH memory.
The SCD dot turns off when you obtain a dump with IBM TotalStorage Tape
Diagnostic Tool (ITDT) or SCSI command, or update the drive firmware.
Note: If the drive dump is stored in RAM memory (SCD dot on solid), the dump
will be lost when you turn OFF the power or reset the drive.
Status lights
Use this information for the status lights on the front panel of the drive.
The status lights (see “Front panel of the drive” on page 2) are LEDs that provide
information about the state of the drive. The Ready status light is green and the
Fault status light is amber, and solid or flashing when lit. The Encryption status
light is white.

Note: The white Encryption status light will be on when the tape drive has a
cartridge loaded and all data on this cartridge is encrypted (excluding the label).
This applies to LTO Ultrium 6 and Ultrium 5 cartridges only.
Table 6 on page 19 lists the conditions of the status lights and Single-character
display (SCD) and provides an explanation of what each condition means.
