4.4.3 Drive Tray LEDs
Two (2) LED indicators are located on the right side of each drive tray. (See
Figure 4-4
) 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 faulty drive. Replacing the wrong drive can fatally
fail a logical array.
