3-8 SPARC Enterprise T1000 Server Service Manual • April 2007

■ Solaris Predictive Self-Healing (PSH) technology – A feature of the Solaris OS,

uses the fault manager daemon (fmd) to watch for various kinds of faults. When

a fault occurs, the fault is assigned a unique fault ID (UUID), and logged. PSH

reports the fault and provides a recommended proactive replacement for the

DIMMs associated with the fault.

3.1.1.3 Troubleshooting Memory Faults

If you suspect that the server has a memory problem, follow the flow chart (see

TABLE 3-1). Run the ALOM CMT showfaults command. The showfaults

command lists memory faults and lists the specific DIMMS that are associated with

the fault. Once you identify which DIMMs to replace, see Chapter 5 for DIMM

removal and replacement instructions. It is important that you perform the

instructions in that chapter to clear the faults and enable the replaced DIMMs.

3.2 Using LEDs to Identify the State of

Devices

The server provides the following groups of LEDs:

■ Front and rear panel LEDS (FIGURE 3-2, FIGURE 3-3, and TABLE 3-2)

■ Power supply LEDs (FIGURE 3-3 and TABLE 3-3)

These LEDs provide a quick visual check of the state of the system.
