Status Reporting
The three disk drive status LEDs (see Figure 4–2) define the operational status of each
drive. To determine the drive status you must observe all three LEDs (see Table 4–1).
Figure 4–2. Disk Drive LEDs Display
Disk Status
The drives have two green and one amber LEDs that are either O N , O FF , or F LASHING .
Since the status LED displays are easily interpreted, they are the most commonly used
indicators of drive status. The symbols for these conditions are shown in Table 4–1.
Drive Activity LED
This green LED indicates the drive
activity, that is drive being accessed,
spinning-up, and so forth.
On-line LED
This green LED indicates if the drive is
operational, non-operational, part of
RAID set, a replacement drive, a spare
drive, or a rebuilding RAID drive.

status as either operational (O
FF ) or
failed (O N ). CXO6695A
