2.4 Using ILOM for Diagnosis and Repair
Verification
The Sun Integrated Lights Out Manager (ILOM) is contained on firmware on the
service processor in the Sun Blade T6320 server module. ILOM enables you to
remotely manage and administer your server module.
Note – ILOM also contains an ALOM-CMT compatibility shell. For more
information about ALOM-CMT compatibility see the Sun Integrated Lights Out
Manager 2.0 Supplement for Sun Blade T6320 Server Modules, 820-2546. Appendix D of
this service manual also provides some information about the ALOM CMT CLI.
ILOM enables you to run remote diagnostics such as power-on self-test (POST), that
would otherwise require physical proximity to the server module serial port. You
can also configure ILOM to send email alerts of hardware failures, hardware
warnings, and other events related to the server module or to ILOM.
The ILOM circuitry runs independently of the server module, using the server
module standby power. Therefore, ILOM firmware and software continue to
function when the server module operating system goes offline or when the server
module is powered off.
Faults detected by ILOM, POST, and the Solaris Predictive Self-healing (PSH)
technology are forwarded to ILOM for fault handling (
FIGURE 2-6).
In the event of a system fault, ILOM ensures that the Service Action Required LED is
lit, FRU ID PROMs are updated, the fault is logged, and alerts are displayed (faulty
FRUs are identified in fault messages using the FRU name. For a list of FRU names,
see
TABLE 1-3).
