VVOL Management Information
Additional information called VVOL management information (metadata) is necessary for VVOLs. VVOL
management information is usually synchronized with the master information in the ETERNUS SF Storage
Cruiser and saved to a dedicated FTV within the ETERNUS AF container. The dedicated FTV is automatically
created in the storage container when creating a VVOL.
