There's no obvious sysctls related to fans, but there are IPMI raw sequences available[1] which I can send to the remote BMC: ipmitool -I lanplus -U ... -P ... -H ... raw 0x3c 0x14 etc Has anybody got a better solution to managing fans & temperature? # demsg [14935] ipmi0: on acpi0 [14935] ipmi0: SSIF interface not supported on ACPI # sysctl hw.ipmi dev.ipmi hw.ipmi.cycle_wait: 10 hw.ipmi.wd_pretimeout_countdown: 120 hw.ipmi.wd_startup_countdown: 0 hw.ipmi.wd_shutdown_countdown: 0 hw.ipmi.wd_timer_actions: 3 hw.ipmi.wd_init_enable: 1 hw.ipmi.on: 1 dev.ipmi.0.%parent: acpi0 dev.ipmi.0.%pnpinfo: _HID=APMC0D8A _UID=0 _CID=IPI0001 dev.ipmi.0.%location: handle=\_SB_.I2C4.IPI_ dev.ipmi.0.%driver: ipmi dev.ipmi.0.%desc: IPMI System Interface dev.ipmi.%parent: there is no /dev/ipmi device btw. main-n258204-33de921ca874 [1]: https://download.lenovo.com/servers_pdf/bmc_command_list_specification_v0.1.1.pdf A+ Dave
