Clustering

Hello Experts,
I have a quick question.Does the terracota server array(TSA) needs to be UP in both the servers which are in clustering or else Is it the case one of the primary server which acts as active needs to be up ?
Because while starting both the TSA’s ,the primary(active) is running and the other one got shutdown by giving the error as below:
