4.2 Status-indicating LEDs

4.2.1 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-

indicating LEDs distributed over the active components in the following ways:

4.2.2 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.
