3.3 Using ALOM CMT for Diagnosis and
Repair Verification
The Advanced Lights Out Manager (ALOM) CMT is a system controller in the
server that enables you to remotely manage and administer your server.
ALOM CMT enables you to run diagnostics remotely such as power-on self-test
(POST), that would otherwise require physical proximity to the server's serial port.
You can also configure ALOM CMT to send email alerts of hardware failures,
hardware warnings, and other events related to the server or to ALOM CMT.
The ALOM CMT circuitry runs independently of the server, using the server's
standby power. Therefore, ALOM CMT firmware and software continue to function
when the server OS goes offline or when the server is powered off.
Note – Refer to the Advanced Lights Out Manager (ALOM) CMT Guide for
comprehensive ALOM CMT information.
Faults detected by ALOM CMT, POST, and the Solaris Predictive Self-healing (PSH)
technology are forwarded to ALOM CMT for fault handling (
In the event of a system fault, ALOM CMT ensures that the Service 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 Appendix
FIGURE 3-9
ALOM CMT sends alerts to all ALOM CMT users that are logged in, sending the
alert through email to a configured email address, and writing the event to the
ALOM CMT event log.
