Configuring disaster recovery with the DR wizard


Configuring disaster recovery with the DR wizard
Prev	Configuring disaster recovery for Enterprise Vault	Next

In an Enterprise Vault environment, the Disaster Recovery Configuration Wizard (DR wizard) assists you to perform the following tasks for the selected service group:

Clone the storage configuration
Configure Volume Replicator replication and global clustering

You will need to exit the wizard after the storage cloning task to install the application, configure the Enterprise Vault service group, and configure Enterprise Vault for the cluster environment. Then you start the wizard again.

The DR Wizard list of service groups shows only those that 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:

SFW HA 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.
Enterprise Vault is configured for HA at the primary site and the EV service group is online on the primary site.
Enough free disk space is available at the secondary site to duplicate the storage configuration at the primary site.
For an IPv4 network, one static IP address is available per application service group to be created.
For an IPv4 network, a minimum of one static IP address per site is available for each application instance running in the cluster.
Global Cluster Option (GCO) is installed at the primary and secondary site, and, for an IPv4 network, one static IP address is available at each site for configuring GCO.
The service group to be cloned can use either IPv4 IP addresses or IPv6 addresses but not a mixture of both.
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 VVR configurations that include a Bunker secondary site.

In addition, see the following replication prerequisite:

See Setting up security for Volume Replicator.

To start configuring disaster recovery with the DR wizard

Start the DR Configuration Wizard from the Solutions Configuration Center. Click Start > All Programs > Symantec > Veritas Cluster Server > Solutions Configuration Center or, on Windows 2012 operating systems, from the Apps menu in the Start screen. Expand the Solutions for Enterprise Vault tab and click Disaster Recovery Configuration > Clone the storage on the secondary site> Disaster Recovery Configuration Wizard.

Note:

By design, the DR wizard requires specific settings for the Lanman attributes on the primary and secondary sites. Before beginning the DR configuration, the wizard checks for these values, and if they are not set as required, the wizard will automatically proceed with setting these values, both at the primary and secondary sites.

In the Welcome panel, review the prerequisites to ensure that they are met and click Next.

In the System Selection panel, complete the requested information:

System Name

Enter the IP address or Fully Qualified Host Name (FQHN) of the primary system where the application is online.

If you have launched the wizard on the system where the application is online at the primary site, you can also specify localhost to connect to the system.

In the Service Group Selection panel, select the Enterprise Vault service group for which you want to configure the storage and replication.
The panel lists only service groups that contain a MountV resource. The service group must not have a child service group, since the DR wizard does not support such a configuration for VVR replication.

Click Next.
In the Secondary System Selection panel, enter the Fully Qualified Host Name (FQHN) or the IP address of the secondary system for which you want to configure disaster recovery.
Click Next.

In the Replication Options panel, select the replication method. Although you must select the replication method now, configuring replication and the global cluster option is done later, after service group creation. For Enterprise Vault, select the option to configure Volume Replicator and the Global Cluster option (GCO).

Configure Volume Replicator and the Global Cluster Option (GCO)	Select this option if you want to configure Volume Replicator replication. Select this option even if you plan to configure Volume Replicator replication or the GCO option manually. This option is required for the wizard to configure the storage cloning correctly for a Volume Replicator environment. The wizard verifies each configuration task and recognizes if a task has been completed successfully. You cannot mix replication methods. That is, if your primary site is using array-based replication, and you select the Volume Replicator option, the wizard will warn you that you cannot use Volume Replicator replication for the disaster recovery site.
Configure EMC SRDF and the Global Cluster Option (GCO)	Select this replication option if you want to configure the settings for the VCS EMC SRDF agent. All disks used for the service group on the primary site must belong to an EMC SRDF array. Select this option even if you plan to configure EMC SRDF replication or the GCO option manually. The wizard verifies each configuration task and recognizes if a task has been completed successfully.
Configure Hitachi TrueCopy and the Global Cluster Option (GCO)	Select this replication option if you want to configure the settings for the VCS Hitachi TrueCopy agent. All disks used for the service group on the primary site must belong to a Hitachi TrueCopy array. Select this option even if you configure GCO manually. The wizard verifies each configuration task and recognizes if a task has been completed successfully.
Configure the Global Cluster Option (GCO) only	If you select this option, the DR wizard does not configure any replication settings. It configures the global cluster option. Select this option if you want to use the wizard in an array-based replication environment that is not supported by this wizard. You must configure replication manually after you finish the wizard. If you select the GCO only option, the DR wizard sets up the storage and service group configuration on the secondary site for an array-based hardware replication environment. Therefore, you cannot use this option to clone the storage and service group for a Volume Replicator replication environment.

Click Next.

Continue with cloning the storage.
