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 6 in
Figure 3 on page 13). To copy the dump, see Function Code 5: Copy
Drive Dump on page 52.
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.
Status Lights
The status lights (2, 3 and 4 in Figure 3 on page 13) are light-emitting
diodes (LEDs) that provides information about the state of the drive. The
Ready status light is green and the Fault status light is amber, and (when
lit) solid or flashing.
