Single-character Display (SCD)
The SCD (5 in Front Panel of the Drive on page 12) presents a single-
character code for:
• Error conditions and informational messages
• Diagnostic or maintenance functions (while in maintenance mode
only)
Appendix A, Error Codes and Messages 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 42 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 (8). To copy
the dump, see Function Code 5: Copy Drive Dump on page 49.
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 (by using xTalk or a 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.
