Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 92h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, subcommand=39h |
| 5 | [7]: command response mode 0- synchronous. The BMC has a return value, and the response needs to be parsed. [6]: clearance mode 1- Clear the specified memory. 0- Clear all [5:0]: segment, 1-based. For high-performance servers such as 9032, each segment indicates a 4-socket partition. The BDF is numbered in the 4-socket system. To be compatible with earlier products and facilitate unified BMC management, the 8100 and other 4-socket or lower-socket systems do not need to distinguish BDFs by segment. Therefore, the segment is always 0. |
| 6 | CPU ID, reserved. It is valid when bit 6 of byte 5 is set to 1. |
| 7 | Channel ID, reserved. It is valid when bit 6 of byte 5 is set to 1. |
| 8 | DIMM ID, reserved. It is valid when bit 6 of byte 5 is set to 1. |
| 9:17 | Reserved field. The default value is 0. |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion Code d6- indicates that the command is not registered with the BMC and is not supported. |
| 2:4 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
