Table 5-4 Advanced Entry Class Troubleshooting (continued)

Action

Symptom/Condition

Step

Front panel LEDs indicate that the server detected a fatal error that
it cannot recover from using OS recovery routines (system health is
flashing red, internal health is steady green, external health is steady
green, and power is steady green).
1. Capture the MCA dump with the EFI command:errdumpmca .

If the system can boot the OS, you can capture binary MCA dump
files online.

2. Examine the iLO 2 MP logs for entries related to processors,

processor power modules (PPMs), shared memory, and core I/O
devices. See

“Errors and Reading Error Logs” (page 154)

for

information.

The problem is fixed when the MCA does not repeat, or the source
of the MCA has been determined and repaired.

Machine Check Abort (MCA)
occurs during server operation;
the server reboots the OS.

8a

The front panel LEDs indicate that the server detected a fatal, front
side bus error caused by MBEs reading cache or DIMM, or by any
parity in the I/O path between SBA, LBA, or HBA (system health is
off, internal health is flashing amber, external health is steady green,
and power is steady green).
System firmware gathers and logs all error data for this MCA event.
1. Examine the iLO 2 MP logs for entries related to processors,

processor power modules (PPMs), shared memory, and core I/O
devices. See

“Errors and Reading Error Logs” (page 154)

for

information.

The problem is fixed when the MCA does not repeat.

Machine Check Abort (MCA)
occurs during server operation;
server reboot of OS is prevented.

NOTE:

The troubleshooting

actions for this step are identical
to those in Step 8a, except that
the server in this step must be
hard reset to begin the booting
process

NOTE:

You must hard reset the

server to clear the fatal condition
and boot the OS.

Troubleshooting Tools

There are a number of tools available for troubleshooting HP Integrity rx3600 servers, including
LEDs, online and offline diagnostics, and system fault management tools.

LEDs

The HP Integrity rx3600 server provides front panel LED, diagnostic panel LED, and FRU health
LEDs, which allow you to monitor system health.

Front Panel

The front panel of the HP Integrity rx3600 server contains the power button/System Power LED,
Internal Health LED, External Health LED, System Health LED, UID Button/LED, and an INIT
button. The server uses flashing states (for example, flashing amber or red) on these LEDs to
indicate a warning or an error. See

Figure 5-1

for a detailed layout of these front panel indicators

and buttons.

When you power on the server, the LEDs light up as follows:

1.

Power LED turns green when the system starts to power up

2.

External health indicator turns green when the BMC powers on

3.

Internal health indicator turns green when the BOOT_START event is received from system
firmware

NOTE:

BOOT_START

can be determined by LED states on the I/O backplane board.

4.

The system health indicator turns green when the firmware leaves exit boot services
and the server starts to boot an OS.
