A remote command device is a volume that is used to transfer CCI commands to a command device on an external storage system. To use a remote command device, you map to an external volume that is already configured as a CCI command device on the external storage system. The mapped volume then becomes a remote command device.
After mapping to an external command device, you can issue CCI commands (for example, ShadowImage, TrueCopy, or other commands) to the remote command device in the local storage system. The CCI commands are relayed from the remote command device to the command device in the external storage system where they are executed, as shown in the following figure.
Note: When you map to an external command
device, the license for Universal Volume Manager is not required.
