SQL Server 2012 clustered instance
We have reached the last article of this series. To close this series out,let’s discuss how to add a node into an existing SQL Server clustered instance. The following steps are performed either to add one more node to some already installed clustered instance, or to continue the installation of a brand new clustered instance.
Configure Server
We will repeat most of the steps done on Node (1)
1.Now open Server Manager , select Local Server , right click on Ethernet(), and rename it to Domain.
2.Double click on domain, then select Properties to set a static IP address. Uncheck these three options:
3.Double click on Internet protocol version 4, select Use the following IP address, set IP address with192.168.10.2 and Preferred DNS with 192.168.10.100 , and leave Default Gateway empty.
4. We can change the computer name and join it to "SQL2" domain.
2.Double click on domain, then select Properties to set a static IP address. Uncheck these three options:
- Linked-Layer Topology Discovery Mapper I/O Driver
- Linked-Layer Topology Discovery Responder
- Internet Protocol Version 6 (TCP/IPv6)
Heartbeat connection
After restarting the SQL1 virtual machine, we need to add a new heartbeat connection.
1. Right Click on the virtual machine name & select Setting
2. From Virtual Machine Setting click Add, to add a new network adapter and click Next.
3. Select "Custom: Specific virtual network", and from the list and click finish.
4. Sign in to SQL1 by using domain Administrator login.
5. Open "Server Manager", click on "Local Server", select Ethernet1, and rename it to "HeartBeat".
6. Double click on HeartBeat, then select Properties to set a static IP address. Uncheck these three options:
4.It is recommended to run configuration validation tests.
5.Enter SQLDemo in Cluster Name , unchecked the heartbeat connection, and enter 192.168.10.200 and click on Next.
1. Run setup. In the SQL Server Installation Center click on Advanced, then click on Advanced cluster preparation.2. From Virtual Machine Setting click Add, to add a new network adapter and click Next.
3. Select "Custom: Specific virtual network", and from the list and click finish.
4. Sign in to SQL1 by using domain Administrator login.
5. Open "Server Manager", click on "Local Server", select Ethernet1, and rename it to "HeartBeat".
6. Double click on HeartBeat, then select Properties to set a static IP address. Uncheck these three options:
- Linked-Layer Topology Discovery Mapper I/O Driver
- Linked-Layer Topology Discovery Responder
- Internet Protocol Version 6 (TCP/IPv6)
7. Double click on Internet protocol version 4, select Use the following IP address, set IP address with 192.168.20.2 , and leave Default Gateway and DNS Servers empty. Then click on Advanced.
