As part of normal processing in a TS7700 Virtualization Engine, a customer can specify that after a certain period of time after being returned to scratch, the contents of a volume can be deleted. The ExpiDate and ExpiTime fields contain Date and Time when the volume can be deleted. The related field in the VTS GUI display is "Earliest Deletion On".
