This Gauge32 value reports the numeric progress percentage of the FSM currently running against an FC SAN border — the uplink boundary where a UCS fabric interconnect connects out into the external Fibre Channel SAN. An admin can watch this counter to see whether a long-running operation, such as bringing up a monitoring session, is actually advancing or has stalled at a fixed percentage. For example, a value stuck at the same number across repeated polls would tell an admin the FSM has hung partway through, even before it times out or errors.
