Updating the SQL Server IP address
You configure the VCS Lanman agent to update the DNS server with the virtual IP address for the SQL Server instance that is being brought online. The Lanman agent resource is created automatically as part of the SQL Server service group. However, you need to edit the default Lanman settings.
You must specify the following attribute settings for the Lanman agent, at a minimum:
DNSUpdate | True This setting causes the update of the SQL Server IP address on the DNS server. |
DNSCriticalForOnline | True The server will not be able to come online if the DNS update is not successful. |
DNSOptions | PurgeDuplicate Removes duplicate DNS entries from the DNS servers. |
More information on Lanman agent settings is provided in the agent documentation.
See Cluster Server Bundled Agents Reference Guide.
The procedure shows how to edit the Lanman resource of an existing SQL Server service group from the VCS Cluster Manager Java Console. You do this after you create the service group on the primary site and again on the secondary site after creating the service group there.
To configure the Lanman agent resource to update the SQL Server IP address
- Start the Cluster Manager Java Console, log on to the cluster, and open the Cluster Explorer window (click anywhere in the active Cluster Monitor panel).
- In the Cluster Explorer configuration tree, expand the SQL Server service group and expand Lanman.
- Under Lanman, right-click the resource icon (labeled with the service group name and the "-Lanman" suffix) and click View > Properties View.
- Expand the Properties View window as necessary to see all attributes under Type Specific Attributes.
- Edit the following attribute settings by locating the row containing the setting, clicking the Edit icon in that row, and editing the setting as follows in the Edit Attribute dialog box. Leave Global (the default) enabled to apply the attribute to all nodes in the cluster. If initially prompted to switch to read/write mode, click Yes.
DNSUpdateRequired
Check DNSUpdateRequired and click OK.
DNSCriticalForOnline
Check DNSCriticalForOnline and click OK.
DNSOptions
Under Vector Values, click the plus icon to display the list, select PurgeDuplicate and click OK.
- If your site uses additional DNS servers, edit the setting for AdditionalDNSServers to specify the IP addresses.
- In the Cluster Explorer window, click File > Save Configuration, and then click File > Close Configuration.
- If you are configuring a resource for the web servers, continue with that procedure; otherwise, log off the cluster and exit the Cluster Manager.
