The SSUM sends a message to the SSUA to run the newly upgraded image in one-shot
mode. This message is passed to the BMC via a “write status word” request.
After setting one-shot mode, the SSUM requests to reboot the BMC firmware.
This is a very important part of the whole BMC upgrade process, because if an image
running in one-shot mode fails to initialize its communication interfaces (with the NPU
or ShMC), there is no possibility to send a reboot request that will cancel the one-shot
mode and automatically restore the previous version of the BMC image. Therefore,
there is a timeout for the establishment of a connection with the ShMC and NPU that is
implemented in the BMC that ensures automatic reboot in case of such an error.
Next, after the control plane ensures that the new image is operational, the SSUM
sends a validation request to the SSUA that accepts the current image selection for
subsequent reboots.
