+## Failover cluster manually
+
+The `resource move` command creates a constraint forcing the resource to remain on the target node.  After executing the `move` command, executing resource `clear` will remove the constraint so it is possible to move the resource again or have the resource automatically fail over. 
+
+```bash
+# pcs resource move <sqlResourceName> <targetNodeName>  
+# pcs resource clear <sqlResourceName> 
+```
+
+The following example moves the **mssql** resource to a node named **vm2**, and then removes the constraint so that the resource can move to a different node later.  
+
+```bash
+# pcs resource move mssql vm2 
+# pcs resource clear mssql 
+```
+
+## Monitor and troubleshoot failover cluster
+
+View the current cluster status:
+
+```bash
+# pcs status  
+```
+
+View live status of cluster and resources:
+
+```bash
+# crm_mon 
+```
+
+View the resource agent logs at `/var/log/cluster/corosync.log`
+
+## Add a node to a cluster
+
+1. Check the IP address for each node. The following script shows the IP address of your current node. 
+
+   ```bash
+   # ip addr show
+   ```
+
+3. The new node needs a unique name that is 15 characters or less. By default in Red Hat Linux the computer name is `localhost.localdomain`. This default name may not be unique and is too long. Set the computer name the new node. Set the computer name by adding it to `/etc/hosts`. The following script lets you edit `/etc/hosts` with `vi`. 
+
+    ```
+   # vi /etc/hosts
+    ```
+
+   The following example shows `/etc/hosts` with additions for three nodes named `sqlfcivm1`, `sqlfcivm2`, and`sqlfcivm3`.
+
+    ```
+    127.0.0.1   localhost localhost4 localhost4.localdomain4
+    ::1         localhost localhost6 localhost6.localdomain6
+    10.128.18.128 fcivm1
+    10.128.16.77 fcivm2
+    10.128.14.26 fcivm3
+    ```
+    
+    The file should be the same on every node. 
+
+1. Stop the SQL Server service.
+
