The bus adapter that connects the canister to the enclosure midplane has not been detected.
This node error does not, in itself, stop the node canister becoming active in the system. However, the bus might be being used to communicate between the node canisters in a clustered system. Therefore, it is possible that this node error indicates the reason why the critical node error 550 A cluster cannot be formed because of a lack of cluster resources is reported on the node canister.
