Configuring High Availability on NSHA1 and NSHA2 (Configuration Utility) From the Student Desktop, use an HTTP connection to the NSHA1 and NSHA2 configuration utilities logged on as the nsroot user for this task. 1. Configure NSHA2 to stay secondary during the election process for High Availability. Take note of the settings/configuration prior to configuring HA. a. NSHA2: Expand the System node and click High Availability . b. NSHA2: Click Node ID 0 in the Nodes pane, then click Edit .

Configure NSHA1 and NSHA2 to function as a high availability pair. Set NSHA2 as the remote node on NSHA1 and specify both nodes to use the nsroot logon credentials. a. NSHA1: Expand the System node, then click High Availability . b. NSHA1: Click Add in the Nodes pane. The Create HA Node dialog box opens. c. NSHA1: Type 172.16.0.10 in the Remote Node IP Address field, verify that Configure remote system to participate High Availability setup and Turn off HA Monitor interface/channels that are down are both selected. d. NSHA1: In the Remote System Login Credential , enter the nsroot/nsroot credentials, then click Create. 3. Refresh the NetScaler system configurations and verify that NSHA2 is set up as the Secondary node on NSHA1. a. NSHA1 and NSHA2: Expand the System node, then click High Availability . b. NSHA1 and NSHA2: Click the Refresh option in the upper right corner of the Configuration Utility window. c. NSHA1 and NSHA2: Verify that 172.16.0.5 appears as the Primary and 172.16.0.10 appears as the Secondary. 4. Enable NSHA2 Node state to actively participate in High Availability. a. NSHA2: Expand the System node, then click High Availability . b. NSHA2: Click Node ID 0 in the Nodes pane and click Edit . c. NSHA2: Select ENABLED (Actively Participate in HA) in the High Availability Status drop-down menu. d. NSHA2: Click OK . Testing the High-Availability Configuration (Configuration (Configuration Utility) From the Student Desktop, use an HTTP connection to the NSHA1 and NSHA2 configuration utilities logged on as the nsroot user for this task. 1. Verify the current state of the high availability pair. a. NSHA1 and NSHA1: Expand the Network node and select IPs . b. NSHA1 and NSHA2: Notice the system-owned IP addresses on both NSHA1 and NSHA2. Verify that the SNIP on NSHA1 is duplicated to NSHA2. 2. Ping the NetScaler SNIP continually a. From the Student Desktop, open the Command Prompt and type ping -t 172.16.0.90 . 3. Test the high-availability configuration by forcing a failover on NSHA1.
