This is the rn (Relative Name), the single naming segment that, appended to its parent's dn, forms the full dn for this one instance of the finite-state-machine record tracking the asynchronous, multi-step workflow UCS Manager runs against the domain's identity subsystem (for example, resyncing identity state between the two fabric interconnects or with UCS Central). UCS Manager derives this segment automatically from the object's own defining attribute (such as an address, index, or configured name), so seeing a distinctive rn like this is how you tell one MetaSystemFsm row apart from every sibling row under the same parent. For this class the rn typically looks like 'fsm-meta'.
