On a SourceMask object -- a fault/event source mask attached to an Org, controlling which fault sources are visible within that organization -- cucsOrgSourceMaskMask is an enumerated state/type value reporting which fault/event source categories are masked from view within this organization. An admin reads this enumeration because it distinguishes between the specific operating modes or states that a SourceMask instance can be in, which affects how UCS Manager and connected hosts behave. For example, an admin diagnosing behavior on a particular SourceMask instance would check cucsOrgSourceMaskMask to see which specific mode or state is currently configured or active.
