This value is a text description of the current step in the finite-state-machine (FSM) task associated with the policy that controls how long UCS Manager retains VM and vNIC inventory records after they disappear from vCenter. An admin reads cucsVmLifeCyclePolicyFsmStageDescr to understand in plain terms what UCS Manager is currently doing while executing this VM life-cycle policy's background task, without needing to decode raw FSM state codes. For example, cucsVmLifeCyclePolicyFsmStageDescr might describe that the retention policy task is currently waiting on cleanup of old VM records, telling an admin the task hasn't stalled -- it's just mid-cycle.
