The following describes the workflow for configuring an environment required to use TrueCopy, Universal Replicator, or global-active device (GAD).

The following figure shows the workflow for configuring an environment.

Connecting physical paths
Use cables to connect between hardware objects according to the configuration required for the operation, such as between the host and the storage system, and between the primary site and the secondary site.
Installing software products
Install software products that are required for remote copy operations.
Registering information about the remote storage system
Register information about the remote storage system on the REST API server of the local storage system. At the same time, information about the local storage system can be registered, as the remote storage system, to the REST API server of the remote storage system.
Changing the port attribute
For VSP 5000 series storage systems, you will need to change target ports to bidirectional ports. For VSP E series, VSP G350, G370, G700, G900 storage systems and VSP F350, F370, F700, F900 storage systems, you do not need to change the port attribute.
Creating a remote connection
Create a remote connection by specifying a remote path. If you use an iSCSI port, register in advance the information about the iSCSI port of the remote storage system for the iSCSI port of the local storage system.
Creating a journal
Create a journal by specifying a journal volume.
Setting the quorum

Specify settings related to the quorum.

When creating a global-active device pair, you must configure a quorum regardless of whether you are using configuration where volumes are set for quorum disks or not.

For configurations where volumes are set for quorum disks, first make sure that the following conditions have been met.

  • The two storage systems on which the global-active device environment is to be built and the external storage system for the quorum disks are connected by a physical path.
  • The volumes on the external storage system for the quorum disks are mapped to the two storage systems on which the global-active device environment is to be built.
Creating volumes
Create volumes to be used for a pair.
Allocating volumes
Set LU paths so that the host can access the volumes in the storage system.
Setting up the virtual storage machine
Create a virtual storage machine in the storage system, and then specify the required settings.
Setting the GAD reserved attribute of S-VOL
For the virtual LDEV number of S-VOL, set the GAD reserved attribute number.

For details on configuring a remote copy environment, see the manual of each software product or System Administrator Guide.
