Site Recovery Manager is an Disaster Recovery solution from VMware. In previous post we have checked on how to recover virtual machines at the DR Site using Site Recovery Manager. Site Recovery Manager comes with additional feature called IP Customization where you can customize the IP Address settings of the virtual machines when they are recovered at the DR Site. IP Customization allows you to configure different IP Ranges for the recovery site.
The most commonly modified virtual machine recovery property is IP customization. Many of organizations have different IP address ranges at the protected site and recovery sites. When a virtual machine is failed over, Site Recovery Manager can automatically change the network configuration (IP address, default gateway, etc.) of the virtual network interface card(s) in the virtual machine. This functionality is available in both failover and fail-back operations. So using the IP Customization you can change the Network configuration of the virtual machine while recovering.
Now we know what is IP Customization, So Let’s see how to configure IP Customization in SRM Step by Step:
Login to vSphere web client.
Go to Site Recovery.
Click “OPEN Site Recovery” to access the Site Recovery Manager configuration.
Expand the Configure section.
Choose Network Mappings.
Below the Network Mappings you can see IP Customization option.
Click Add to configure IP Customization.
Provide the IP Address ranges and Network Configuration for the IP Customization.
Click Add to save.
You can verify that IP Customization is listed and all the Network Settings are proper.
You can do same for the DR Site by selecting DR vCenter and Add IP Customization.
That’s it, Using this way we can easily configure IP Customization in Site Recovery Manager. So now when VM will be recovered at the Recovery Site, This IP settings will be used to configure Networking inside the virtual machine. Make sure you have proper Network connectivity and configuration in place so you don’t loose the connectivity.
Note: IP Customization can take bit time at the time of recovery of the virtual machine , Before adding IP Customization make proper plan and then Implement.
