You can customize IP settings for virtual machines for the protected site and the recovery site. Customizing the IP properties of a virtual machine overrides the default IP settings when the recovered virtual machine starts at the destination site.

If you do not customize the IP properties of a virtual machine, Site Recovery Manager uses the IP settings for the recovery site during a recovery or a test from the protection site to the recovery site. Site Recovery Manager uses the IP settings for the protection site after reprotect during the recovery or a test from the original recovery site to the original protection site.

Site Recovery Manager supports different types of IP customization.

Use IPv4 and IPv6 addresses.

Configure different IP customizations for each site.

Use DHCP, Static IPv4, or Static IPv6 addresses.

Customize addresses of Windows and Linux virtual machines.

Customize multiple NICs for each virtual machine.

See the Compatibility Matrixes for vCenter Site Recovery Manager 5.1 for the list of guest operating systems for which Site Recovery Manager supports IP customization.

You associate customization settings with protected virtual machines. As a result, if the same protected virtual machine is a part of multiple recovery plans, then all recovery plans use a single copy of the customization settings. You configure IP customization as part of the process of configuring the recovery properties of a virtual machine. If you do not customize a NIC on one site, the NIC uses the IP settings from the other site.

You can apply IP customizations to individual or to multiple virtual machines.

If you configure IP customization on virtual machines, Site Recovery Manager adds recovery steps to those virtual machines.

Guest OS Startup

The Guest Startup process happens in parallel for all virtual machines for which you configure IP customization.

Customize IP

Site Recovery Manager pushes the IP customizations to the virtual machine.

Guest OS Shutdown

Site Recovery Manager shuts down the virtual machine and reboots it to ensure that the changes take effect and that the guest operating system services apply them when the virtual machine restarts.

After the IP customization process finishes, virtual machines power on according to the priority groups and any dependencies that you set. The power on process happens immediately before the Wait for VMTools process for each virtual machine.

Note

To customize the IP properties of a virtual machine, you must install VMware Tools or the VMware Operating System Specific Packages (OSP) on the virtual machine. See http://www.vmware.com/download/packages.html.

You can customize IP settings for individual virtual machines for both the protected site and the recovery site.

The IP address map reporter generates an XML document describing the IP properties of protected virtual machines and their placeholders, grouped by site and recovery plan. This information can help you understand the network requirements of a recovery plan.

Manually configuring IP settings for many virtual machines at a recovery site can be time consuming and can lead to errors in configuration. To facilitate the configuration process for multiple virtual machines, Site Recovery Manager includes the DR IP Customizer tool.
