You have reached the maximum limit of 25 Clone Groups. You have reached the maximum limit of 8 Clones per source LUN. You have reached the maximum limit of 50 Clones per storage system. You have reached the maximum limit of 100 Clones per storage system.

10.

A customer upgraded to a newer version of SnapView via NDU and now the previous running snapshot sessions are no longer available. What is most likely the problem?

The customer did not export the SnapView cache prior to the upgrade. The customer has not committed Access Logix and/or the SnapView software.
