On a MountInstFsm object -- the finite-state-machine (FSM) task UCS Manager runs while it mounts, unmounts, or validates that NFS mount -- cucsNfsMountInstFsmRmtErrCode is a Gauge32 counter/value representing the numeric remote error code returned by the far-end system the last time this FSM stage invoked it. An admin monitors this number because it quantifies the internal progress or configuration of that specific MountInstFsm instance's operation, which is otherwise invisible outside UCS Manager's own FSM engine. For example, a rising or stalled value on cucsNfsMountInstFsmRmtErrCode tells the admin whether the MountInstFsm instance's task is actively making progress or has stopped moving forward.
