This is a short text description of the most recent asynchronous workflow (finite state machine, or FSM) that Cisco UCS Manager ran against the domain-wide extpol Registry. On cucsExtpolRegistryFsmDescr, this description is what an admin reads first in the fault/event log to understand, in plain terms, what UCS Manager was last trying to do to this specific registry object — for example negotiating or re-establishing its connection. For example, this might read 'Establishing external policy connection' or 'Re-validating registration' for this specific object.
