Brief Overview of the LEDs

 

 

 

The following devices all come with LEDs that inform subsystem managers about the opera-

 

tional status of the component on which they are mounted. The RAID subsystem has status-

Drive Tray LEDs

 

 

Two (2) LED indicators are located on the right side of each drive tray. (See Figure 4.1) Refer to Table 4.2 for the LED definitions. When notified by a drive failure message, you should check the drive tray indicators to find the correct location of the failed drive. Replacing the wrong drive can fail two members of a logical array and thus render the array data unrecover- able.
