Performing the rehearsal operation for virtual machines
Use the Rehearsal option on the Resiliency Platform console to ensure the disaster recovery readiness of the assets in your protected resiliency groups.
From version 3.5, Rehearsal operation can be performed on Azure or (Azure Stack) data center when it is deployed as source as well as a target data center.
For recovery on AWS cloud:
The time taken to complete the Rehearsal operation depends on the size and the number of volumes. If the recovery data center is in AWS cloud, then to reduce the time taken to complete the snapshot creation task during Rehearsal, you may take a snapshot of the volumes manually before running the Rehearsal operation. Before taking a snapshot, ensure that the replication state is Consistent. Since, in AWS the subsequent snapshots are only incremental, the time taken to create snapshots during Rehearsal is significantly reduced. Which reduces the overall time taken to complete the operation.
Note:
This setting is specific to recovery of virtual machines from VMware to VMware if Resiliency Platform Data Mover is used and recovery of physical machines to VMware data center:
While performing the rehearsal operation, DRS automation level for the target Replication Gateway should be set to manual or it should be disabled.
For recovery from AWS region to AWS region: If the rehearsal security group is different for source virtual machine and rehearsal operation is performed on source (after migrating to target) then, first you need to edit the resiliency group to select the valid rehearsal security group; and then perform the rehearsal operation.
To perform the rehearsal operation
- Prerequisites
See Prerequisites for rehearsal operation for virtual machines.
- Navigate
Assets (navigation pane) > Resiliency Group(s) tab
- Double-click the resiliency group to view the details page. Click Rehearsal.
- Select the target data center and then click Next.
The rehearsal option on the Resiliency Platform console is used to ensure the disaster recovery readiness of the assets in your protected resiliency groups. You can perform the rehearsal operation for the resiliency groups where CDP is enabled.
To perform rehearsal operation for virtual machines for CDP
Navigate
Assets (navigation pane) > Resiliency Group(s) tab
- Double-click the resiliency group to view the details page. Click Rehearsal.
- Select the target data center and then select the recovery points to perform the rehearsal operation.
- Click Next.
Before you perform the rehearsal operation again, you need to ensure that the previous rehearsal is cleaned up by running the Cleanup Rehearsal operation.
