This value records the previous state the finite-state-machine (FSM) task for the policy that controls how long UCS Manager retains VM and vNIC inventory records after they disappear from vCenter was in before its current one. An admin reviewing a policy task that seems stuck compares cucsVmLifeCyclePolicyFsmPrev to the current state to see whether the task is progressing normally through its expected sequence or has stalled at a repeat state. For example, if cucsVmLifeCyclePolicyFsmPrev keeps showing the same value on repeated polls, an admin can suspect the retention-policy task is looping rather than completing.
