sm-lan-mode doesn't work

[yuzhichang]

exporter config:

modules:
  default:
    user: root
    pass: calvin
    driver: "LAN_2_0"
    privilege: "admin"
    timeout: 10000
    # collectors: [bmc, ipmi, dcmi, sel, chassis, sm-lan-mode]
    collectors: [sm-lan-mode]
    exclude_sensor_ids: []

I got error:

level=debug ts=2021-12-18T07:03:14.189Z caller=freeipmi.go:143 msg=Executing command=ipmi-raw args="[0x0 0x30 0x70 0x0c 0 --config-file /tmp/ipmi_exporter-427c4cb2556d3eaaeb284a5498daf106 -h 192.168.102.98]"

The ipmi-raw command returns only 2 bytes:

Hi, thanks for reporting. I suspect we may have to add some flags to this collector to set the hardware version it should work with. Can you please let me know which type of SM hardware you are trying to query and also, check if any of the corresponding variations of the raw command listed in this support article produce a correct result (3 octets)?

Thanks, Conrad

I installed freeipmi, ipmitool, ipmicfg on host (PowerEdge R720xd, CentOS 7.9.2009). The management nic address of this host is 192.168.102.98.

Sorry once more for the late reply. You are using Dell hardware here, but the sm-lan-mode module only works with Supermicro hardware. See https://github.com/prometheus-community/ipmi_exporter/blob/master/docs/metrics.md#supermicro-lan-mode-setting
