Session commands
The commands that are available for a session depend on the session type, and for some commands, the storage system type.
Commands are issued to Copy Services Manager sessions. Any subsequent command that is issued to an individual session is not processed until the first command is completed. Some commands, such as the Start command, can take an extended amount of time to complete because the commands set up the hardware relationships. You can continue to issue commands to other sessions during this time. When a command is completed, the console shows the results of the command.
