26.6.2 Shared DASD between VSE and OS/390 (vs. Cloned DASD)
As mentioned in the previous section, it is risky to share DASD between VSE and
OS/390 because there is no mechanism such as GRS to guarantee serialization
between the two systems. If you decide to share, you must strictly control
updates from the two systems, or be prepared to restore volumes, files and
catalogs should they become corrupted.
