This Gauge32 is the error code returned from a remote invocation UCS Manager made to another node 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 a nonzero code here points to a failure that occurred on the remote (e.g. IOM or fabric interconnect) side of a management call, not locally in UCS Manager itself. A nonzero fsmRmtInvErrCode on this backplane link alongside a stalled fsmProgr is the pair of fields an admin would quote when opening a TAC case about a chassis that won't finish discovery.
