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).

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.

 

Drive Failure LED

 

This amber LED indicates the drive

 

status as either operational (OFF) or

CXO6695A

failed (ON).

Disk Status

The drives have two green and one amber LEDs that are either ON, OFF, or FLASHING. 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.
