Thanks for your answer.
Actually, our process is very simple. We want to regain the snap capacity by taking the current snapshot in simplex mode. Because developer no longer need that data. Afterwards, we want to take a snapshot again because renewal is requested. We used tradinital raidcom commands like pairsplit -S and paircreate with horcm files.
Is teardown equivalent of pairsplit -S command? and then trigger our data flow again to refresh our thin image snapshot ?
