Verify that you know the IP address of the vSphere Replication appliance in your environment. To
check the IP address of the vSphere Replication appliance, select the vCenter Server in the inventory
tree, navigate to the Manage tab, click vSphere Replication, and click About.
n
Verify that you have root user credentials for the vSphere Replication appliance.
n
Verify that TCP port 22 is open on the vSphere Replication appliance, and that SSH connections are
enabled. See topic Unable to Establish an SSH Connection to the vSphere Replication Appliance in the
vSphere Replication Administration document.
Procedure
1 Use a TCP client to connect to the vSphere Replication appliance and log in as the root user.
2 Run the following command to configure the ports for tunnel connections.
/opt/vmware/vcta/bin/cell-management-tool
configure-vcta-server -prl LOW -prh HIGH
Where LOW and HIGH define the range of ports to be used for tunnel connections. To use only one
port, type the port number as the value for LOW and HIGH.
For example, the following command configures the vCloud Tunneling Agent to use only port 10001.
/opt/vmware/vcta/bin/cell-management-tool
configure-vcta-server -prl 10001 -prh 10001
NOTE You can designate any free TCP port in your environment for the communication between ESXi
hosts and the vCloud Tunneling Agent, but you must verify that all ESXi hosts and the vCloud
Tunneling Agent are configured to use the same ports.
3 Run the following command to restart the vCloud Tunneling Agent.
service vmware-vcd restart
Configuring the Connection to the Cloud
In addition to installing and configuring the vSphere Replication appliance, you must configure the
connection to your cloud provider.
You can configure a connection to the cloud provider before you start the Configure Replication wizard or
while you configure a replication task.
Connect to a Cloud Provider Site
Before you configure replication tasks to the cloud, you configure the connections between your vSphere
environment and virtual data centers that belong to your cloud organizations.
You can connect a vCenter Server to multiple virtual data centers, and a virtual data center can be connected
to multiple vCenter Server instances. However, you can have only one connection between a source
vCenter Server and a target virtual data center.
Prerequisites
Verify that you have user credentials for a cloud organization in which vCloud Air is enabled. Your cloud
provider enables the Disaster Recovery to Cloud service per your contract.
Procedure
1
On the vSphere Replication tab under Manage, click the cloud connection icon .
The Connect to a Cloud Provider wizard opens.
