Edit Command Devices wizard

The System Administrator can enter CCI commands from open-system hosts to perform such as TrueCopy or ShadowImage operations or both on logical devices. For example, CCI commands can be used to create and split pairs. If you want to allow the System Administrator to enter CCI commands from open-system hosts, you must specify at least one logical device as the command device. If desired, you must also apply command device security to other logical devices in the storage system.

Use Edit Command Devices window to edit command devices.
