Monitoring SDV capacity
If an SDP is not used, the SDV should be monitored on a periodic basis to ensure that adequate remaining capacity leeway is maintained.
Initialize SDV
Even if no copy sessions are running, some operational problems can cause large volumes of writes to occur, reducing the SDV or SDP capacity available to the copy session when it is set. In these cases, the "Initialize SDV" operation should be performed.
Note that when a Snap Data Volume is initialized, any existing data on it will become inaccessible, so this data should be backed up beforehand, using OS commands.
