Usage Guidelines

None

Example

  • Enable the SecureVideo function of disk domain 0.
    developer:/>change disk_domain securevideo disk_domain_id=0 securevideo_switch=On 
    WARNING: You are about to enable the SecureVideo function of the disk domain. 
    After the SecureVideo function is enabled, writes/reads in the disk domain can still be processed even when multiple disks in the disk domain are faulty, but the correctness of the writes/reads in the faulty disks is not ensured. The overall reliability is lower than that of a functional disk domain. Particularly, if a multi-copy feature is configured in the disk domain and multiple disks are faulty, data consistency cannot be ensured between copies. Such multi-copy feature can be HyperMirror, HyperReplication, HyperSnap, SmartMigration, and others. 
    Suggestion: Before enabling the SecureVideo function, make sure that it is required by services. 
    Have you read warning message carefully?(y/n)y 
    Are you sure you really want to perform the operation?(y/n)y 
    Command executed successfully.
  • Disable the SecureVideo function of disk domain 0.
    developer:/>change disk_domain securevideo disk_domain_id=0 securevideo_switch=Off 
    WARNING: You are about to disable the SecureVideo function of the disk domain. 
    If SecureVideo has been enabled for the disk domain and incorrect data exists due to failures of multiple disks, incorrect data on the disk domain cannot be automatically restored after SecureVideo is disabled. This may cause inconsistent data to occur on following services. 
    Suggestion: If the data in the disk domain is not useful, delete the disk domain and create a new one to run your services.

    developer:/>change disk_domain securevideo disk_domain_id=0 service_time=10Hours 
    CAUTION: You are about to change the SecureVideo service time. This time indicates the period during which SecureVideo can ensure continuous service running in case of the failures of multiple disks. 
    Suggestion: This configuration is valid only when SecureVideo has been enabled. Confirm that you have enabled SecureVideo and understand the meanings of different parameters. 
    Do you wish to continue?(y/n)y
