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.
