Hi,
The IPMI Completion Codes in range 80-BEh are command-specific so
it must consider the command before translate it.
The Get Session Challenge completion code response is implemented
according with IPMIv2_0rev1_0.pdf, page 306, table 22-20.

it must consider the command before translate it.
The Get Session Challenge completion code response is implemented
