Drive Tray LEDs
Two LED indicators are located on the right side of each drive tray. (See Figure 4.1) Refer to
Table 4.2 for 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 cause fatal failure of a logical array.
