Configuring VMware virtual machines for disaster recovery using Hitachi True Copy replication

This section lists the prerequisites to enable data replication using Hitachi True Copy (HTC) for the Veritas Resiliency Platform environment.

Ensure that Hitachi Command Control Interface (HORCM CCI) is installed on a host and that the HTC Instances are already set up for the replication between the primary and remote arrays.
Ensure that HORCM CLI executes properly on the host. This is required for discovery and all other operations.

Ensure that the HTC replicated LUNs are assigned to the respective VMware ESX Servers.

Note:

If any changes are made to storage or storage-adapters available to the ESX/ESXi host or cluster, you must perform storage rescan, storage adapter rescan or both depending on the changes made.

Ensure that the Symmetrix LUNs composing the datastore of the virtual machine's disk are grouped together into a HTC.

Note:

For HTC based replication in Resiliency Platform, all virtual machines that consume storage from an HTC Instance must belong to the same resiliency group. An Instance is a collection of Volume Groups that helps in maintaining write consistency during replication. A resiliency group is a unit of management and control that you create in Resiliency Platform. Related virtual machines are organized into a resiliency group and managed and monitored as a single entity.

Resiliency Platform configurations:

Using the Resiliency Platform console Infrastructure settings, you add the asset infrastructure for each data center (the production and recovery data centers). The following is a summary of the steps. More information is available.

See the Veritas Resiliency Platform Deployment Guide.

Resiliency Platform configurations:

Configure the VMware vCenter Server to send traps to the IMS.
Add the HTC discovery hosts to the respective data centers. HTC discovery hosts are hosts on which HORCM package is installed and HTC device groups are created.
Add the vCenter Servers to their respective data centers. The user needs to have vCenter administrator privileges.

Note:

Ensure that the virtualization server and ESX server are discovered successfully.
Add the host where the HTC Instances are configured to their respective data centers.
