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. To copy the
dump, see
Function Code 5: Copy Drive Dump
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 IBM Tape
Diagnostic Tool (ITDT) 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 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.
