Table 2. Troubleshooting charts Device Suggested action Blade server problem Blade servers turn off for no apparent reason. All blade bays must have a blade server, expansion unit, or filler blade in them. Blade bays that do not have these items installed or have them installed improperly disturb airflow in the BladeCenter unit with an adverse effect on BladeCenter unit cooling. If the BladeCenter unit begins to overheat, blade server processors will begin to slow down and will eventually turn off the system. Blade server does not turn off during Red Hat Linux 7.3 shutdown. Issuing any of the Linux shutdown commands shuts down the operating system, but does not turn off the blade server. The blade server shuts down to the point where a message is displayed on the management module saying that the blade server is off, but the blade server power-on LED remains lit. Complete the instructions provided for Red Hat Linux in the User's Guide or the Command-Line Interface Reference Guide for your management module type to enable Wake On LAN for both onboard Broadcom integrated Ethernet controllers. This will allow the blade server to restart using Wake on LAN even if the Linux shutdown is incomplete and the blade server does not turn off. Forcing a blade server to turn off Complete the following steps to turn off a blade server after an incomplete Linux shutdown: 1. Manually press the power-control button on the front of the blade server (behind the control panel door) to turn off the blade server. Turning off the blade server in this way is considered an improper shutdown by the Wake on LAN feature, and the Wake on LAN feature will not restart the blade server. 2. Unlatch and slide the blade server partially out of the BladeCenter; then, reinstall it to reset the blade server power state and re-enable its previously programmed Wake on LAN capability. Blade server does not turn off during SuSE Linux 8.0 shutdown. Issuing any of the Linux shutdown commands shuts down the operating system but does not turn off the blade server. The blade server shuts down to the point where a message is displayed on the management module saying that the blade server is off, but the blade server power-on LED remains lit. A blade server running SuSE Linux 8.0 will not turn off during shutdown if ACPI is not enabled. Complete the following steps to enable ACPI: 1. Type the following command: modprobe ospm_system 2. Type the following command to save this setting upon subsequent reboots: echo "/sbin/modprobe ospm_system" >> /etc/init.d/boot.local Blade server does not turn The problem occurs after installing the second microprocessor option or after on, the amber system-error replacing a failed microprocessor in a two-way Blade server. LED on the BladeCenter system-LED panel is lit, the The processor with the lowest feature set and stepping level must be used as the amber blade error LED on the Bootstrap Processor (BSP). This is Microprocessor 1 in location U66. Move the blade server LED panel is lit, microprocessor in location U66 to location U70, and move the microprocessor in and the system-error log location U70 to location U66. contains the following message: "CRUs MisMatched". 58 BladeCenter E Type 8677 and 1881: Hardware Maintenance Manual and Troubleshooting Guide
