Note:

The DR wizard cannot be used if you are setting up DR in a non-shared storage environment.

The Disaster Recovery Configuration Wizard (DR wizard) assists you to perform the following tasks for the selected service group:

Clone the storage configuration (Volume Replicator replication) or prepare a temporary storage configuration for application installation (array-based hardware replication)
Clone the service group
Optionally, configure Volume Replicator replication, or configure the VCS hardware replication agent settings for EMC SRDF or Hitachi TrueCopy

Configure global clustering

Warning:

To use the Disaster Recovery Configuration Wizard in an array-based hardware replication environment that is not configured by the wizard, you must first run the wizard to configure global clustering before configuring replication.

The wizard allows you to exit after the logical completion of each task. Each time you re-start the wizard, you specify the primary site system, service group, secondary site system, and replication method, as described in the following procedure. Clicking Next then takes you to the start page of the process following the one that you had last completed.

The DR Wizard list of service groups shows only those that contain a MountV resource. For a dependent service group to be listed, the parent service group must also contain a MountV resource.

Warning:

Once you have completed configuring replication and global clustering with the DR wizard, you cannot use the wizard to change the method of replication.

Before running the DR wizard to configure disaster recovery, ensure that you meet the following prerequisites:

InfoScale Enterprise is installed and a cluster is configured at the secondary site. Ensure that the name assigned to the secondary site cluster is different than the name assigned to the primary site cluster.
Your application or server role is configured for HA at the primary site and all required services are running at the primary site.
The clusters taking part in the DR configuration should have distinct names.
Enough free disk space is available at the secondary site to duplicate the storage configuration at the primary site.
Global Cluster Option (GCO) is installed at the primary and secondary site, and one static IP address is available at each site for configuring GCO.
For IPv4 networks, static IP addresses are available to enter for the following (for IPv6, they are generated during configuration):
- One static IP address per application service group to be cloned.
- One static IP address at each site for configuring GCO.
- If using Volume Replicator for replication, a minimum of one static IP address per site for each application instance running in the cluster.
The service group to be cloned can use either IPv4 IP addresses or IPv6 addresses but not a mixture of both.
To configure IPv6 settings, the wizard must be launched from a system on which the IPv6 stack is installed.
For Volume Replicator replication, the service group to be cloned cannot contain a child service group.
A VCS user is configured with the same name and privileges in each cluster.
If a firewall exists between the wizard and any systems it needs access to, the firewall is set to allow both ingoing and outgoing TCP requests on port 7419.

Note:

The DR wizard does not support Volume Replicator configurations that include a Bunker secondary site.

In addition, see the following replication prerequisites, depending on the replication method you are using:

See Setting up security for Volume Replicator.
