10 Repeat Step 6 through Step 9 to configure recovery site or protected site settings, if required.

For example, if you configured IP settings for the protected site, you might want to configure settings

for the recovery site.

11 Repeat the configuration process for other NICs, as required.

Customizing IP Properties for Multiple Virtual Machines

You can customize the IP properties for multiple virtual machines on the protected and recovery sites by

using the DR IP Customizer tool and by defining subnet-level IP mapping rules.

In previous releases of Site Recovery Manager, you customized IP properties for multiple virtual machines

by using the DR IP Customizer tool. In addition to DR IP Customizer, with Site Recovery Manager 5.8 you

can customize IP properties for multiple virtual machines by defining subnet-level IP customization rules.

You can use subnet-level IP customization rules in combination with DR IP Customizer.

Using DR IP Customizer is a fast way to define explicit IP customization settings for multiple virtual

machines by using a CSV file.

You apply subnet-level IP customization rules to virtual machines by using the vSphere Web Client.

Virtual machines that you configure by using DR IP Customizer are not subject to subnet-level IP

customization rules. You can achieve the same IP customization results by using either DR IP Customizer or

IP subnet rules. In Site Recovery Manager 5.8, the DR IP Customizer provides more control over IP

configuration of individual virtual machines, such as customizing static IPv6. This control is useful when

you upgrade from an earlier version of Site Recovery Manager in which you used DR IP Customizer.

Customizing IP Properties for Multiple Virtual Machines By Using the DR IP

Customizer Tool

The DR IP Customizer tool allows you to define explicit IP customization settings for multiple protected

virtual machines on the protected and recovery sites.

In addition to defining subnet IP mapping rules, you can use the DR IP Customizer tool to apply

customized networking settings to virtual machines when they start on the recovery site. You provide the

customized IP settings to the DR IP Customizer tool in a comma-separated value (CSV) file.

Rather than manually creating a CSV file, you can use the DR IP Customizer tool to export a CSV file that

contains information about the networking configurations of the protected virtual machines. You can use

this file as a template for the CSV file to apply on the recovery site by customizing the values in the file.

1 Run DR IP Customizer to generate a CSV file that contains the networking information for the

protected virtual machines.

2 Modify the generated CSV file with networking information that is relevant to the recovery site.

3 Run DR IP Customizer again to apply the CSV with the modified networking configurations to apply

when the virtual machines start up on the recovery site.

You can run the DR IP Customizer tool on either the protected site or on the recovery site. Virtual machine

IDs for protected virtual machines are different at each site, so whichever site you use when you run the DR

IP Customizer tool to generate the CSV file, you must use the same site when you run DR IP Customizer

again to apply the settings.

You can customize the IP settings for the protected and the recovery sites so that Site Recovery Manager

uses the correct configurations during reprotect operations.
