Table 5-4 Advanced Entry Class Troubleshooting (continued)

Step

Symptom/Condition

8a

Machine Check Abort (MCA)

 

occurs during server operation;

 

the server reboots the OS.

8b

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.

Action

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.

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.

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 5-1for 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.

INTEGRITY RX3600 specifications

The HP Integrity RX3600 is a high-performance server designed to address the demanding needs of enterprises that require robust computing capabilities, reliability, and scalability. Part of the HP Integrity server family, the RX3600 is built on the Itanium architecture, which is known for its exceptional processing power and advanced features that support mission-critical applications.

One of the main features of the RX3600 is its capability to handle multiple workloads with ease. The server supports up to 64 GB of RAM, allowing for efficient multitasking and enhanced performance in data-intensive environments. Its modular design also enables organizations to scale up their systems by adding additional memory or processors as needed, making it a flexible choice for growing businesses.

The RX3600 is equipped with HP's Integrity Virtual Machines (VMs), which provide virtualization capabilities that allow businesses to run multiple operating systems and applications on a single physical server. This not only maximizes resource utilization but also simplifies management by reducing the number of physical servers required in the data center.

Another significant characteristic of the RX3600 is its advanced reliability features. The server is designed with fault-tolerant components, including redundant power supplies and cooling systems. This ensures that the server remains operational even in the event of hardware failures. Additionally, HP's Error Correction Code (ECC) memory helps detect and correct data corruption, further enhancing the system's reliability.

For security, the HP Integrity RX3600 includes built-in features such as Secure Boot, which ensures that the server boots using only trusted firmware and software. This protects against unauthorized changes and vulnerabilities that could compromise data integrity.

In terms of connectivity, the RX3600 offers multiple I/O options, including advanced networking capabilities that support high-speed data transfer and improved bandwidth. This is critical for organizations that rely on data-intensive applications and need to maintain seamless connectivity.

Furthermore, the server supports a range of operating systems, including HP-UX and Linux, making it adaptable to various enterprise environments. Its robust performance, reliability, and scalability make the HP Integrity RX3600 an ideal choice for businesses looking to optimize their IT infrastructure and support their critical workloads with confidence.
