Configuring a resource for the web servers
You can add a process resource to the SQL Server service group to enable switching to the web servers at the site where the SQL Server service group is brought online. The process resource executes a Perl script to update the DNS server IP address for the web servers.
You add the process resource after you create the service group on the primary site. After you create the service group on the secondary site, you add the process resource to that service group as well.
The procedure shows how to add a resource using the Java Console. You can also use other methods, as described in the VCS documentation.
See Cluster Server Administrator's Guide.
Verify that the Perl executable, the scripts, and the customized settings file is available from the systems on which the service group is configured.
In addition, ensure that DNScmd.exe is installed to the same drive as the SFW HA application.

- In the Cluster Explorer configuration tree, right-click the name of the SQL service group and click Add Resource. If prompted to switch to read-write mode, click Yes.
- In the Add Resource dialog box, specify a name for the resource and in the Resource Type list, click Process.
