Example

  • Enable the function of allowing HyperMetro to be configured between two storage arrays of different performance and specifications.

    developer:/>change hyper_metro general mismatch_config_enabled=allowed
    WARNING: You are about to enable the function of allowing HyperMetro to be configured between two storage arrays of different performance and specifications. By default, this function is disabled. After the function is enabled, the configuration of the HyperMetro domain does not check whether the two storage arrays are of the same performance and specifications.
    Suggestion: Confirm that you want to perform this operation.

    Command executed successfully.
  • Turn on the switch for checking the mappings of local LUNs in HyperMetro pairs.

    developer:/>change hyper_metro general lunmap_check_switch=on
    CAUTION: You are about to change the status of the function that checks the HyperMetro local LUN mapping. By default, this function is enabled.
