light and single-character display, that when visible provides drive informational and error conditions.
The single-character display shows either a single character, a dot (in the lower right of the display), or
both.
Note: The SCD can be seen through the windows of expansion units, and for full-height drives only. If
you have a base unit without expansion units, or if you have half-height drives, the SCD cannot be seen.
"Single-character display (SCD) codes" 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 until no errors remain.
The SCD is blank during normal operation.

Table 39 gives descriptions of the errors and messages that pertain to the drive. For troubleshooting tips,

can be lost. After you force a drive dump, do not turn OFF the power to the drive or you might lose the
dump data.
