Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion code. Generic, plus following command specific: 81h=FRU device busy. The requested cannot be completed because the implementation of the logical FRU device is in a state where the FRU information is temporarily unavailable. This could be due to a condition such as a loss of arbitration if the FRU is implemented as a device on a shared bus. Software can elect to retry the operation after at least 30 milliseconds if this code is returned. Note that it is highly recommended that management controllers incorporate builtin retry mechanisms. Generic IPMI software cannot be relied upon to take advantage of this completion code. |
