This operation enables you to create a third-party quorum server for HyperMetro domains. When the communication between storage devices in a HyperMetro pair becomes abnormal, the quorum server decides which site continues to provide services, thereby greatly improving service continuity.
Prerequisites
To enable quorum links to be added to storage arrays successfully, check the following items before creating a quorum server.
- The system time of the storage arrays and quorum server is correct. The validity period of the default arbitration certificate is 10 years (starting from September 2015). Ensure the system time of the quorum server is correct so that the default arbitration certificate is valid.
- The service IP addresses of the quorum server are correctly configured and correct firewall port (30002) is enabled.
- The white list of the quorum server is configured correctly. (You do not need to check this item if the default security policy is used.)
Procedure
- Choose Data Protection > Block Protection > Quorum Server.
- Click Create.
The Create Quorum Server page is displayed.
- Set the properties of the quorum server. Table 1 describes related parameters.
