Creating a HyperMetro Domain

Prerequisites

At least one remote device has been added to the storage system.

Context

• A HyperMetro domain is a collection of local and remote devices and a quorum server (which is optional). It defines the relationships among the local and remote devices as well as the quorum server.
• During initial synchronization, the remote device serves as the secondary end of HyperMetro.
• A quorum server must be added to the HyperMetro domain if you want to use the quorum server arbitration mode. You must create a quorum server for the local and remote storage systems.
• If no quorum server is configured for the HyperMetro domain, the preferred site continues providing services by default in the event of a fault. If a quorum server is configured, the quorum server determines which site continues providing services in the event of a fault.
• When creating a HyperMetro domain, you only need to perform the operation on the local storage system.
• After creating a HyperMetro domain, you can create HyperMetro pairs or CGs in the domain.

Procedure

1. Choose Data Protection > Configuration > HyperMetro Domains.
2. Click .

   The Create HyperMetro Domain page is displayed.

3. Specify the name and description for the HyperMetro domain.
   • The name must be unique.
   • The name contains 1 to 31 characters.
   • The name can contain only letters, digits, underscores (_), hyphens (-), and periods (.) and must start with a letter or digit.
   • The description can be left blank or contain up to 127 characters.

4. Determine whether to enable Quorum Server.
   • If you enable Quorum Server:
     1. In the Remote Device area, select a remote device that you want to add to the HyperMetro domain.
     2. In the Quorum Server area, select a quorum server that you want to add to the HyperMetro domain.
     3. You can click to create a quorum server.
        1. Set Name and Description for the quorum server.
           • The name must be unique.
           • The name contains 1 to 31 characters.
           • The name can contain only letters, digits, underscores (_), periods (.), and hyphens (-).
           • The description can be left blank or contain up to 127 characters.
        2. Set the Local Quorum Server Links and Remote Quorum Server Links.
           • You can click or to add or remove a link.
           • Configure at least one local and one remote quorum link.
           • To ensure reliability, it is recommended that you add at least one link from the quorum server to each storage controller.
           • This operation will create a quorum server on both the local and remote storage systems.
   • If you use the static priority mode:

     In the Remote Device area, select a remote device that you want to add to the HyperMetro domain.

5. Click OK.

   Confirm your operation as prompted.
