This reports the depth in UCS Manager's org-hierarchy tree at which the policy settings for this equipment service-policy definition were actually resolved. Because this object defines how and when a piece of equipment (a blade, PSU, fan module, IO module, etc.) may be serviced or physically removed, a policyLevel of 0 means the effective settings came straight from the root organization, while a higher number means a sub-organization further down the tree overrode them for this specific instance. In practice this reads 0 for the vast majority of UCS domains, and only climbs to 1 or 2 once an admin has built a multi-tenant org structure and pushed a more specific policy onto a child org.
