Protection parameters and operations

The RAID storage systems have protection checking parameters for each LU,
and these parameters are set through CCI and its command device. CCI
supports the following commands to set and verify the parameters for
protection checking for each LU:
• raidvchkset: Sets the protection checking parameter for the specified
volumes.
• raidvchkdsp: Shows the protection checking parameter for the specified
volumes based on the CCI configuration definition file.
• raidvchkscan: This command has three different uses depending on the
options used with the command.

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