This appendix includes the following scenarios:
This section lists the pre-requisites to enable data replication using EMC RecoverPoint when the hosts are a part of a Microsoft failover cluster. For RecoverPoint-based replication, all applications consuming storage from a consistency group must belong to the same resiliency group. A consistency group is a collection of LUNs that helps in maintaining write consistency during replication.
Ensure that RecoverPoint consistency groups are set up on the control host for the replication between the primary and remote arrays.
Ensure that EMC RecoverPoint groups are set up for the CRR replication between the primary and Secondary RecoverPoint Appliance.
Ensure to enable the Failover Cluster roles on the Windows Server 2012R2 hosts at the production and recovery data centers.
Ensure that you have created Microsoft failover cluster using the required nodes at the production and recovery data centers.
Ensure that you have created the cluster shared volume (CSV) on the replicated shared disk on the application server at the production data center. On the application hosts configured at the recovery data center, re-scan the storage on all the Microsoft failover cluster nodes.
Configure application on the production data center's Microsoft failover cluster with their data on the replicated CSVs.
Once you have performed the necessary configurations, proceed with disaster recovery specific tasks.
Veritas Resiliency Platform configurations:
Add Windows 2012 R2 hosts to the Infrastructure Management Server (IMS) using the Add Hosts operation.
Add the array control host where the RecoverPoint consistency groups are configured, to the each IMS using the Add Hosts operation.
Add Symmetrix, CLARiiON, or VNX enclosure using the Add Enclosure option. Provide the discovery host name and the SYMCLI, NaviSecCLI, or Navisphere CLI location on this discovery host. This operation returns the list of Symmetrix, CLARiiON, or VNX arrays (local and remote) that are accessible to the host. To configure disaster recovery for applications, select one or more local arrays.
Add RecoverPoint appliance for replication using the Add RecoverPoint operation.
Perform add host, add RecoverPoint appliance, and add enclosure operations for the IMS at the disaster recovery data center as well.
This section lists the pre-requisites to enable data replication using EMC RecoverPoint when the hosts are not a part of a Microsoft failover cluster.
Ensure that RecoverPoint consistency groups are setup on the control host for the replication between the primary and remote arrays.
Ensure that EMC RecoverPoint groups are set up for the CRR replication between the primary and Secondary RecoverPoint Appliance.
Ensure that you have created the volumes on the primary Hyper-V host where the LUNs are read and write enabled. Veritas Resiliency Platform supports only one volume per replicated disk. Windows Storage Space Storage Pool is not supported.
Ensure that you have configured application at the production data centre under the Hyper-V Manager and kept the data files on the replicated volumes.
Ensure that the respective remote disks are in the offline state on the Hyper-V server at the recovery data center. And also verify that no drive letter is assigned to the volumes present on these offline disks.
Once you have performed the necessary configurations, proceed with disaster recovery specific tasks.
