On PowerScale, file shares are renamed or removed. In the PowerProtect Data Manager user interface, under "Assets" page file shares are still visible with "Available" state.

These assets are not marked with "Not Detected" or "Deleted" status.

Discovery jobs for PowerScale are completing successfully.

On the PowerProtect Data Manager server, the discovery-service.log file reports errors and warnings similar to the following:

This is a software defect.

Some Interfaces are not assigned to any AccessZone. During extracting access zone detail using interface from the PowerScale API, it causes nullpointerException.
