DESCRIPTION

On an HP ProLiant ML350 G5 server configured with a single processor, if the HP System Health Application and Insight Management Agents for Linux are installed without the HP OpenIPMI (hp-OpenIPMI) device driver loaded, a console message is displayed indicating that there is a problem with the system fan and that the server will shut down in 60 seconds. After 60 seconds has passed, the server reboots. When this occurs, the following message is written to the /var/log/messages file:

hpasmlited: WARNING: System Fan Removed (Fan 6, Location CPU)

The HP OpenIPMI (hp-OpenIPMI) device driver reports information on the status of the system fan to the HP System Health Application. If the HP OpenIPMI (hp-OpenIPMI) device driver is not loaded, then the OpenIPMI device driver that is included with the Linux kernel is loaded by default. The hpasmlited application uses the IPMI Sensor Device Records (SDRs) to determine what devices are present and working and what action to take. The SDR for Fan 6 is delivered to the hpasmlited application with instructions to shut down the server if the fan is missing or failed. As a result, the HP System Health Application flags the system fan as not being present and shuts down the server. The HP OpenIPMI (hp-OpenIPMI) device driver relies on OEM messages sent by the Base Management Controller (BMC) to shut the server down. The IPMI 2.0 OEM messages are not supported by the standard Linux drivers shipped with the Linux kernel.

When the ProLiant Support Pack for Linux is loaded, the HP OpenIPMI (hp-OpenIPMI) device driver is loaded by default. However, if a user chooses to not load the HP OpenIPMI (hp-OpenIPMI) device driver, then the OpenIPMI device driver that is included with the Linux kernel is loaded.

Note: This does not occur on a ProLiant ML350 G5 configured with two processors.

SCOPE

Any HP ProLiant ML350 G5 server configured with a single processor and running HP System Health Application and Insight Management Agents for Linux and the OpenIPMI device driver that is included with the Linux kernel.

RESOLUTION

To prevent the server from rebooting, load the HP OpenIPMI (hp-OpenIPMI) device driver instead of the OpenIPMI device driver if the HP System Health Application and Insight Management Agents for Linux are installed.
