Overview
Set the Dell PowerEdge fan speed manually to a fixed level (CONCEPT:FM-OS.governance.service-writes-fan-level).
This enables manual BMC fan control via ipmitool raw commands and applies the
requested level directly, bypassing the automatic temperature curve.
Tools
set_fan: Set the fan speed to a specific level (0-100). Levels outside
that range are rejected with a structured error envelope.
Usage
Use this skill when you need to explicitly set the fan speed — for example, to
test cooling performance at a known fan level, strictly control noise, or
temporarily override automatic control. For load-responsive cooling, use the
fan-manager-automatic skill instead.
Safety
- Requires
ipmitool on the host and BMC raw-command access.
- Fan levels are validated to the 0-100 range before any command is issued.
- Manual control persists until automatic control or a reboot resets it.
