Command Example
Request:
bash
ipmicmd -k "0f 00 30 90 5b" smi 0Response:
text
0f 31 00 90 c0Example assuming the BMC is busy: completion code c0 means that the command cannot currently be processed, so no Loadline data is shown. The request is complete. A successful response contains 50 payload bytes and this command has no offset or length selector; for that response, the IPMI user guide recommends ipmitool because ipmicmd returns at most 36 bytes.
