Recovering from Database Corruption on the vSphere Auto Deploy Server
In some situations, you might have a problem with the vSphere Auto Deploy database. The most efficient
recovery option is to replace the existing database file with the most recent backup.

encounter a problem with the vSphere Auto Deploy database.

choose are lost.

vSphere Web Client.

DatabaseError: database disk image is malformed.
If you see the message, replace the existing database with the most recent backup.
