I just received an email about an excellent article on VI:OPS. The article is titled “Automating Network Setting Changes and DNS Updates on Recovery Site Using VMware vCenter Site Recovery Manager“. It includes a PDF file which contains a description for configuring automatic IP-Changes but also includes batch files for DNS updates.

When performing site failover, IT administrators are often faced with challenges to deal with disparate networks on the recovery site:

• Network properties of virtual machines need to be customized according to the network specification of the recovery site.
• Domain Name Server (DNS) records pertaining to these virtual machines need to be updated.

VMware® vCenter Site Recovery Manager (SRM) enables customers to design automated recovery plans that incorporate all these necessary network property changes, relieving them of the repetitive and error-prone manual tasks.

This paper shows the mechanisms that SRM customers can use in order to automate these tasks related to network related changes.
