Virtual light path diagnostics
If you are physically in front of the server, it is easy to track hardware problems by noticing the
first tier of light path diagnostics, using the LED panel at the front of the server shown in
Figure 5-7.
Figure 5-7 LED light path diagnostic panel
Scrolling through the LED panel using the up and down arrows shown in Figure 5-7 will reveal
the hardware subsystem that is experiencing an error.
Most servers are not physically located near the people who manage them. To help you see
the event from a remote location, the IMM2 provides the capability of looking at all tiers of
light path diagnostics via the System Status page under the Hardware Health menu as seen
in Figure 5-6 on page 138. Clicking a hardware component will reveal the hardware
component causing the error. A Hardware Status example of disks is shown in Figure 5-8.

Hardware event log
For more detailed information, including the events that led up to a failure, you can access the
hardware event log. Although not every event in the hardware event log is an event needing
attention, the event log can provide insight to the cause or conditions that led up to the failure.
The event log can be saved to a text file to be sent to IBM support.
