You cannot use volumes in use by SI as destination volumes.Workflow for creating ShadowImage pairs
Use the following workflow to create an SI pair:
If you are creating L1 and L2 pairs, check the status.
For more information about L1 and L2 status and the tasks that you can perform, see L1, L2 pair status and supported pair user tasks.
Select the volume that you want to duplicate. This becomes the primary volume (P-VOL).
You cannot use volumes in use by SI as destination volumes.
Identify the volume that will contain the copy. This becomes the secondary volume (S-VOL).
If you are creating L1 and L2 pairs with different topologies, specify the pair configuration settings
For more information about setting up pair configurations, see Creating L1 and L2 pairs with different topologies.
Create the pair by associating the P-VOL and the S-VOLs.
The VSP G200, G400, G600 storage system starts the initial copy.

(Optional) Suppress copy processing.
