HP Integrated Lights-Out 3 - Manual (Page 113)

The Diagnostics page contains the following sections:
•
iLO Self-Test Results—This section displays the results of internal iLO diagnostics.
The status of each self-test is listed in the Status column. Move the cursor over the status
icons to view a tooltip description. If a status has not been reported for a test, the test is
not listed. ◦
◦ The tests that are run are system dependent. Not all tests are run on all systems. View the
list on the Diagnostics page to verify which tests are performed on your system.
◦ A test might include additional information in the Notes column. This column show the
versions of other system programmable logic, such as the System Board PAL or the Power
Management Controller.
•
Reset iLO—This section contains the Reset button, which enables you to reboot the iLO
processor. Using Reset does not make any configuration changes, but ends all active
connections to iLO. If a firmware file upload is in progress, it is terminated. If a firmware flash
is in progress, you cannot reset iLO until the process is finished. You must have the Configure
iLO Settings privilege to use this feature.
•
Non-Maskable Interrupt (NMI) button—This section contains the Generate NMI to System
button, which enables you to stop the operating system for debugging. The Virtual Power and
Reset privilege is required to generate an NMI.
CAUTION: Generating an NMI as a diagnostic and debugging tool is used primarily when
the operating system is no longer available. NMI is not used during normal operation of the
server. Generating an NMI does not gracefully shut down the operating system, but causes
the operating system to crash, resulting in lost service and data. Use the Generate NMI to
System button only in extreme cases in which the operating system is not functioning properly
and an experienced support organization has recommended that you proceed with an NMI.
Note the following:
◦ Use the Debug feature if a software application hangs the system. Use the Generate NMI
to System button to engage the operating system debugger.
◦ Initiate the dump of an unresponsive host if you want to capture the server context.
•
Redundant ROM Support—You can safely upgrade or configure the server ROM with redundant
ROM support.
◦ The Active ROM table shows the current version and the release date of the system ROM
on the local machine.
◦ The Backup ROM table shows the release date of the backup ROM and the release date
of the backup ROM bootblock. The backup ROM is typically the previously installed
version.
