The start or resume command may be issued to any device and CKD LSS in the master storage control. Once the Global Mirror session is active, all start or resume commands to the master storage control must be issued to the same CKD LSS where the start was issued, as long as the configuration exists. It is strongly recommended that the same device in the master storage control be used for all start and resume commands.
If the command to start or resume a session is issued without the consistency group interval, coordination interval, and coordination drain time specified, and the session is already active, the command is accepted.
