Static persistence

Hi, I have two pool members(A & B) in GTM with load balancing mechanism as static persistence and persistence set to 1800seconds value. My question is if currently all my traffic is persisting to one pool member (A) and it goes down, then will the persistence records clear out or for a certain period of time my GTM and client connection still persist to the down pool member (A).

    If a pool is marked down the persistence records are normally updated on the next query, so traffic will be load balanced to the other pool and a the persistence record will be updated.

     

    So all traffic with a persistence record for pool A would be direct to pool B, if pool A was down, and the persistence records would be updated so even if pool A came back up traffic would still be send to pool B.
