Governing fan speed in Linux

Solution 1:

This is an HP ProLiant server. In order to maximize the benefit of the hardware and its monitoring and temperature regulation features, you should install the HP Management Agents (for RHEL6) or (SuSE) on the system. There's no need to use ipmitool and lm_sensors on HP equipment, as purpose-built tools exist.

Despite this, the ILO4 governs many of these features and out of the box, most Gen8 servers are pretty quiet. Do you have a problem with ambient temperature in your environment? See: HP DL380 G6: Where is Temperature Sensor 30 (I/O Board Zone)?

You should be able to see a 3-D heat map of the server using your ILO's temperature menu.

• Are you certain you're on current firmware with the system?
• Can you post the output of the temperature and fan status?

To install the agents, you can subscribe to the HP SDR YUM repo and simply:

yum install hp-snmp-agents hpssa hp-health hp-smh-templates hpsmh hpssacli hponcfg

This will provide you with some additional tools.

The hplog -t and hplog -f will show temperature and fan speed respectively. This can also be viewed in the ILO4.
