Data Protection facility
The Data Protection Facility permits main operations to volumes that you can see on the host, and
prevents wrong operations. RAID Manager controls protected volumes at the result of recognition
of protection. RAID Manager recognizes only volumes that the host shows. For that purpose LUN
Security is provided for the RAID Manager environment.
The Data Protection Facility ON/OFF is controlled by the security setting for command device. For
details about the security setting for command device, please refer to the following table.
