the host/drive channels.
ATTEN
(Attention)
Red
ON
indicates that a component
failure/status event has occurred.
OFF
indicates that the subsystem and all
its components are operating correctly.
Table 3-1: LCD Panel LED Definitions
NOTE:
During the power-on process, the ATTEN LED will light up
steadily. Once the subsystem successfully boots up with no faults,
the ATTEN LED will turn off.
3.2.2
Drive Tray LEDs
Two (2) LED indicators are located on the right side of each drive tray.
(See
Figure 3-2
) Refer to
Table 3-2
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 (RAID 3/5) and
thus destroy data in it.
