Tasks for a new disaster recovery installation - additional applications

Before setting up disaster recovery at the secondary site, you must complete the high availability configuration for the application on the primary site.

See Tasks for a new high availability (HA) installation - additional applications.

You can also configure disaster recovery for a primary site that is configured as a replicated data cluster.

See Tasks for a new replicated data cluster installation - additional applications.

After setting up an SFW HA environment on the primary site, you can create a secondary or "failover" site for disaster recovery.

The Disaster Recovery (DR) wizard helps you to clone the storage configuration and the service group configuration from the primary site to the secondary site. You can install the application on the secondary site during the DR wizard workflow.

After service group configuration, the DR wizard helps you set up replication and global clustering (GCO option). You can choose to configure replication using Volume Replicator or an agent-supported array-based hardware replication. The DR wizard can configure required options for the VCS agents for EMC SRDF and for Hitachi TrueCopy. To use the wizard with any other agent-supported array-based replication, you must complete configuring global clustering with the wizard before configuring replication on the array.

The DR wizard is available from the Solutions Configuration Center. Veritas recommends using the Solutions Configuration Center as a guide for installing and configuring disaster recovery.

See About the Solutions Configuration Center.

Note:

If you are using non-shared storage (dynamic disk groups monitored using VMNSDg agent), you cannot use the DR wizard to configure disaster recovery. You have to set up DR manually. Refer to the separate workflow table available for configuring DR manually:

See Table: Non-shared storage: Configuring Disaster Recovery.

This chapter describes the process for any generic application or applications such as FileShare and IIS.

The following table outlines the high-level objectives and the tasks to complete each objective.
