Tasks for setting up DR in a non-shared storage environment

The following table outlines the high-level objectives and tasks for a creating a single-node DR configuration at the secondary site. Refer to this table if you are setting up DR in a non-shared storage environment (dynamic disk groups configured using VMNSDg agent).

You cannot use the DR wizard to configure disaster recovery in a non-shared storage environment. You have to configure DR manually.

Note:

Some procedures (for example, configuring Volume Replicator replication) are common if you are setting up a DR or an RDC configuration. To avoid duplication, the topics referenced in this table point to the procedures described in the RDC chapter covered earlier.

Objectives

Tasks

Install InfoScale Enterprise and configure the cluster on the secondary site.

  • Verify the software and hardware prerequisites.

  • Set up the network and storage.

  • Install InfoScale Enterprise.

    Caution:

    Ensure that the name you assign to the secondary site cluster is different from the name assigned to the primary site cluster.

  • Configure disk groups and volumes.

See Setting up the secondary site: Configuring SFW HA and setting up a cluster.

Verify that the application has been configured for high availability at the primary site.

Verify that the application has been configured for high availability at the primary site and that the service groups are online.

See Verifying that your application or server role is configured for HA at the primary site.

Set up the replication prerequisites.

  • Ensure that Volume Replicator replication prerequisites are met.

  • Configure the VxSAS service for Volume Replicator, specifying the cluster nodes at both primary and secondary sites.

See Setting up security for Volume Replicator.

(Secure cluster only) Assign user privileges.

For a secure cluster only, assign user privileges.

See Assigning user privileges (secure clusters only).

Install the application at the secondary site.

  • Review. the prerequisite checklist

  • Install the application.

See Installing and configuring the application or server role (secondary site).

Configure the application service group for VCS (secondary site).

  • Configure the application service group manually using the Cluster Manager (Java Console).

  • Ensure that the name of the service group is the same as that on the primary site.

See Configuring the application service group in a non-shared storage environment.

Set up the replicated data sets (RDS) for Volume Replicator replication.

  • Use the Setup Replicated Data Set Wizard to create RDS and start replication for the primary and secondary sites.

  • Use the Setup Replicated Data Set Wizard to create Replicator Log volumes for the primary and secondary sites.

See Creating the replicated data sets (RDS) for Volume Replicator replication.

Create the Volume Replicator RVG service group.

(Repeat the steps separately on primary and secondary sites.)

  • Create the Volume Replicator RVG service group for the replicated volume group.

  • Use the Cluster Manager (Java Console) to manually create the service group.

  • Create the RVG service group at the primary site and the secondary site separately.

  • Bring the RVG service group online on the primary site.

See Creating the Volume Replicator RVG service group for replication.

Configure the global cluster option for wide-area failover.

  • Link clusters (adding a remote cluster to a local cluster).

  • Convert the application service group that is common to all the clusters to a global service group.

  • Convert the local service group to a global group.

  • Bring the global service group online.

See Configuring the global cluster option for wide-area failover.

Verify the disaster recover configuration.

Verify that the secondary site has been fully configured for disaster recovery.

See Verifying the disaster recovery configuration.

(Optional) Add secure communication.

Add secure communication between local clusters within the global cluster (optional task).

See Establishing secure communication within the global cluster (optional).

(Optional) Add additional DR sites.

Optionally, add additional DR sites to a Volume Replicator environment.

See Adding multiple DR sites (optional).

Handlr service group dependencies after failover.

If your environment includes dependent service groups, review the considerations for bringing the service groups online after failover to the secondary site.

See Recovery procedures for service group dependencies.
