Recognizing Drive Failure

The indicators on the front of each hard drive are visible through the front of the

external storage unit. When a drive is configured as a part of an array and attached

to a powered-on controller, the status of the drive can be determined from the

illumination pattern of these indicators.

Figure 32 and its associated table define the three indicators on the hard drive.

For detailed descriptions of the various indicator combinations, refer to the “Hard

Drives” section in the “Operation and Management” chapter.
