Due to ungraceful shutdown, primary archive has corrupted in Primary PI server (L4) so repaired accordingly. We have observed data gap for few tags only in Primary PI server (L4 server) but data available in secondary PI server (4) for those tags. We can use archive trimming and merging mechanism to fill these gaps in Primary PI server (L4). 


DS--> L3 (collective)--> PI to PI (failover)--> L4 (collective)


Can we use history recovery option in PI to PI interface to fill this gap instead of using archive trimming and merging?
