Evacuating a Recovery VRA

When a VPG is defined, the recovery host to use for each virtual machine in the VPG is specified. If required, you can edit the recovery host for a single or multiple protected virtual machines.

•

To evacuate the recovery host for selected virtual machines, see Evacuating a recovery host VRA for a selected VM.

•

To evacuate the recovery host for all protected virtual machines at once, see Automatically evacuate a recovery host VRA for all VMs.

After evacuating the recovery host, populate the host to enable rebalancing of the environment post evacuation more easily. See Populating a Recovery VRA.

Evacuating a recovery host VRA for a selected VM

To evacuate a recovery host VRA for selected VMs:

In the Zerto User Interface, click SETUP > VRAs.

Select the VRA to change and click Actions > Evacuate Host.

The Evacuate Host window is displayed, listing all the virtual machines being recovered on that host.

Review the list and select the virtual machines to change the target host to another specified target host.

To change the target host for the selected VM, do one of the following:

•

From the bottom left of the window, in the Select replacement host area, click the drop-down list to get a list of available target hosts. Select the target host.

•

In the Target Host column, click the pencil icon which appears to the right of the IP address .

A drop-down list of available target hosts appears. Select the new target host.

•

From the bottom right of the window, click Auto Select the Replacement Host to automatically select the most suitable host for that virtual machine. Auto-selection is based on a load-balancing algorithm.

You can move some virtual machines to one replacement target host, and then by repeating the operation, you can move other virtual machines to a different target host.

After selection of the new Target Host, validation is performed to make sure the selected target host can be used. For example, the datastores used by both the VRAs are accessible from both hosts.

Any implications of the change, such as whether synchronization might be required after the change is also displayed.

Click APPLY.

•

During this operation you cannot edit the affected VPGs, nor attempt a failover, move, failover test, or clone operation.

•

At the end of the operation a Bitmap Sync might be required to resynchronize the protected machines with the recovery VRAs.

Automatically evacuate a recovery host VRA for all VMs

To automatically evacuate the recovery host VRA for all VMs:

In the Zerto User Interface, click SETUP > VRAs.

Select the VRA to change and click Actions > Evacuate Host.

The EVACUATE HOST window is displayed, listing all the virtual machines being recovered on that host and their automatically selected target host.

The auto-selection is based on a load-balancing algorithm.

Load-balancing is executed at the cluster level, meaning the suggested hosts must share the same cluster as the evacuated host.

•

Validation is performed to make sure the selected target host can be used. For example, the datastores used by both the VRAs are accessible from both hosts.

•

Any implications of the change, such as whether synchronization might be required after the change is also displayed.

Click APPLY.

•

During this operation you cannot edit the affected VPGs, nor attempt a failover, move, failover test, or clone operation.

•

At the end of the operation a Delta Sync might be required to resynchronize the protected machines with the recovery VRAs.
