| Completion Code | Description |
|---|---|
| 00h | Command completed normally. |
| C0h | Node busy. Command cannot be processed because command processing resources are temporarily unavailable. |
| C1h | Invalid command. Used to indicate an unrecognized or unsupported command. |
| C2h | Command invalid for a given LUN. |
| C3h | Timeout while processing command. Response unavailable. |
| C4h | Out of space. Command cannot be completed due to insufficient storage space required to execute the given command operation. |

| CFh | Cannot execute duplicated request. This completion code is for devices which cannot return the response that was returned for the original instance of the request.

| D4h | Cannot execute the command due to insufficient privilege level or other security based restriction. |
| D5h | Cannot execute command. Command or request parameters not supported in present state. |
| D6h | Cannot execute command. Parameter is illegal because command sub-function has been disabled or is unavailable. |
