Object Existence Comparison

Comparing two snapshots helps determine whether or not an object exists between the them. If an object exists in one snapshot, but does not exist in the other, the comparison results display the object with an attribute named “existence” and describes it as either “found” or “missing” on either the source or comparison snapshot.

A process family could be running (and thus, “exist”) when you refresh a snapshot and save the Business Application. But if the process is no longer running, and you refresh the snapshot again and save the Business Application, the results change. When you compare the saved snapshot (the “comparison” snapshot) with the currently loaded snapshot (source), the results of the comparison display in the Differences pane.

The results of the selected row show that on the target snapshot, all the listed LUN volumes are missing, meaning they did not exist in the comparison snapshot, but they exist now in the current snapshot.
