This value is the result code of the remote invocation UCS Manager made while running the workflow against this internal backplane link. It matters on the internal Ethernet link that carries a blade's traffic from the chassis I/O Module up to a Fabric Interconnect over the backplane because it is the field that formally distinguishes a successful remote step from a failed one, feeding directly into whether the overall FSM can advance. An fsmRmtInvRslt showing a failure on this backplane link even while fsmStatus still reads 'in progress' warns an admin the workflow is about to retry or fail outright.
