Diagnostics
The Diagnostics option on the System Status tab displays the Server and iLO 2 Diagnostics screen.
The Server and iLO 2 Diagnostic screen displays iLO 2 self-test results, and provides options to
generate an NMI to the system and to reset iLO 2.
NOTE: When connected through the Diagnostics Port, the directory server is not available. You
can log in using a local account only.
The Diagnostics page contains the following sections:
• Non-Maskable Interrupt (NMI) button
The Non-Maskable Interrupt (NMI) button section contains the Generate NMI to System button
which enables you to halt the operating system for debugging. This functionality is an advanced
function and must only be used for kernel-level debugging. The possible uses of the Generate
NMI to System feature include the following:
— Use the Demonstrate ASR feature only if the System Management (health) driver is loaded
and ASR is enabled. The host automatically reboots after an NMI has occurred.
— Use the Debug feature if a software application hangs the system. The Generate NMI to
System button can be used to engage the operating system debugger.
— Initiate the dump of an unresponsive host if you want to capture the server context.
The Virtual Power and Reset privilege is required to generate an NMI. An unexpected NMI
typically signals a fatal condition on the host platform. A blue-screen, panic, ABEND, or other
fatal exception occurs when an unexpected NMI is received by the host operating system,
even when the operating system is unresponsive or locked-up. Generating an unexpected
NMI can be used to diagnose a catatonic or deadlocked operating system. Generating an
NMI crashes the operating system, resulting in lost service and data.
Generating an NMI must only be used in extreme diagnostic cases in which the operating
system is not functioning properly and an experienced support organization has recommended
that you proceed with an NMI. Generating an NMI as a diagnostic and debugging tool is
primarily used when the operating system is no longer available. Generating an NMI must
not be used during normal operation of the server. The Generate NMI to System button does
not gracefully shut down the operating system.
• iLO 2 Self-Test Results
The iLO 2 Self-Test Results sections displays the results of iLO 2 internal diagnostics. iLO 2
performs a series of initialization and diagnostic procedures on the subsystems of the iLO 2
system. The results display on the Server and iLO 2 Diagnostics screen. All tested subsystems
display Passed under normal circumstances. Each test displays one of three results: Passed,
Fault, or N/A.
The status of these self-tests is indicated by the test results and is intended to identify issue
areas. If a Fault test condition is indicated, follow information noted on the screen. The specific
tests that are run is system-dependant. Not all tests are run on all systems. See the iLO 2
Diagnostics page to verify which tests are automatically performed on your system.
• Reset Integrated Lights-Out 2
The Reset Integrated Lights-Out 2 section contains the Reset button which enables you to reboot
the iLO 2 processor. Using Reset does not make any configuration changes. Reset disconnects
any active connections to iLO 2 and completes any firmware updates in progress. You must
