2.4Using 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).
