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.
Initializing SDV
Even if no copy sessions are running, programs may write data to SDV. If SDV capacity becomes large, the "Initialize SDV" operation should be performed with ETERNUS Web GUI or ETERNUS CLI.
When copy session is running, space for SDV or SDP used by the copy session is decreased. In this case, amount of maintaining data may be decreased.
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.
