This string is the overall status of the finite-state-machine workflow currently running against this internal backplane link, such as in-progress, complete, or fail. 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 single field an admin checks first to know whether a pending chassis discovery or link-bring-up operation actually succeeded. An fsmStatus of fail on this backplane link after a chassis re-acknowledge is the trigger for an admin to look at the more detailed fsmRmtInvErrDescr field for the underlying cause.
