|---|---|
| 1 | Completion code. Generic, plus following command specific: 80h=write-protected offset. Cannot complete write because one or more bytes of FRU data are to a write-protected offset in the FRU device. Note that an implementation may have allowed a 'partial write' of the data to occur 81h=FRU device busy. Refer to the preceding table for the Read FRU Command for the description of this completion code |
| 2 | Count written --- count is '1' based |

请求：
ipmicmd -k "0f 00 0a 12 00 00 00 01" smi 0响应：
0f 0b 00 12 00 01说明：本例响应的完成码为 00（成功）。向 FRU 0 的偏移 0000h 写入一个字节 01h；本例假定该位置可写且 FRU 按字节寻址，返回写入数量为 1。
