2.6.4.3Clearing Faults Manually with ILOM

The ILOM set /SYS/clear_fault_action=enabled command allows you to manually clear certain types of faults without replacing a FRU. It also allows you to clear a fault if ILOM was unable to automatically detect the FRU replacement.

2.6.4.4Clearing Hard Drive Faults

ILOM can detect hard drive replacement. However, to configure and unconfigure a hard drive, you must type the Solaris cfgadm command. See Section 3.2, “Hot- Plugging a Hard Drive” on page 3-1. ILOM does not handle hard drive faults. Use the Solaris message files to view hard drive faults. See Section 2.8, “Collecting Information From Solaris OS Files and Commands” on page 2-47.

2.7Using the Solaris Predictive Self-Healing Feature

The Solaris Predictive Self-Healing (PSH) technology enables the Sun Blade T6320 server module to diagnose problems while the Solaris OS is running. Many problems can be resolved before they negatively affect operations.

The Solaris OS uses the fault manager daemon, fmd(1M), which starts at boot time and runs in the background to monitor the system. If a component generates an error, the daemon handles the error by correlating the error with data from previous errors and other related information to diagnose the problem. Once diagnosed, the fault manager daemon assigns the problem a Universal Unique Identifier (UUID) that distinguishes the problem across any set of systems. When possible, the fault manager daemon initiates steps to self-heal the system and take the component offline. The daemon also logs the fault to the syslogd daemon and provides a fault notification with a message ID (MSGID). You can use the message ID to get additional information about the problem from Sun’s knowledge article database.
