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.

Only HORCM_DEV allowed : means to be able to perform the operation for only paired logical volumes described
at HORCM_DEV.

User authentication required: means that only the commands issued by the authorized users can be executed.

CMD security: means that only the devices recognizable from the host can be operated.

The Data Protection Facility uses an enhanced command device that you define using the LUN
Manager software (or SNMP). When you define the command device, the Data Protection Facility
is turned ON or OFF to each command device, which has an attributes to enable the Data Protection
Facility. RAID Manager distinguishes the ON from OFF attribute when RAID Manager recognizes
the command device.

Figure 59 (page 176)

shows the definition of protected volumes.

NOTE:

If the command device is set to enable protection mode, there is no impact on RAID

Manager operations. RAID Manager controls pairs under current specification. For details about
the command operations when the Data Protection Facility is turned ON, see
