The first pass determination of needed volumes is complete for the indicated restore session. It is possible that additional volumes will be needed as individual objects are restored. This can happen for a variety of reasons. Examples of such reasons include: 1. An object spanning from one volume to another, where the second volume is not needed for any other objects during this restore session. 2. An object is found to be damaged and a copy storage pool volume is needed to complete the restore. 3. A volume is unavailable and a copy storage pool volume is needed to complete the restore.
