This is the policyOwner property of a storage connection definition object, a storage connectivity definition specifying how UCS connects to a SAN, including its Fibre Channel zoning type and operational state, indicating whether the object's policy is controlled locally or by a higher-level UCS Central/global policy resolution. An admin deciding whether they can safely edit a storage connection definition's settings locally checks this field first, since a globally-owned policy will simply be overwritten on the next resolution cycle. For example, if policyOwner on a given storage connection definition shows it is owned by a policy source outside the local domain, an admin knows to make the change there instead of on this instance directly.
