9.4.17 Get Payload Shutdown Time-Out Command
When the shelf manager commands the IPMC to shut down the payload (i.e. sends the Activate
FRU (Deactivate) command), the IPMC notifies the payload by forwarding the command
Activate FRU (Deactivate) to the KCS interface. Provided the OpenIPMI driver has registered
this command for notification, the payload gets notified. Upon receiving this notification, the
payload software is expected to initiate the payload shutdown sequence. After performing this
sequence, the payload should send the Graceful Reset command to the IPMC over the payload
Interface to notify the IPMC that the payload shutdown is complete.
To avoid deadlocks that may occur if the payload software does not respond, the IPMC provides
a special time-out for the payload shutdown sequence. If the payload does not send the
Graceful Reset command within a definite period of time, the IPMC assumes that the payload
shutdown sequence is finished, and resets the payload.
