Removing the<br />

primary from an HA<br />

cluster<br />

5 Click the Save icon in the toolbar.<br />

Chapter 17: High Availability<br />

Configuring HA<br />

6 Wait 60 seconds to allow the <strong>Sidewinder</strong> <strong>G2</strong>s to synchronize, and then<br />

reboot each <strong>Sidewinder</strong> <strong>G2</strong> that is part <strong>of</strong> the HA cluster. It is important that<br />

the second <strong>Sidewinder</strong> <strong>G2</strong> be rebooted before the primary is finished<br />

rebooting.<br />

Important: If you do not begin the reboot process for the second <strong>Sidewinder</strong><br />

<strong>G2</strong> before the primary finishes rebooting, it will detect that the second<br />

<strong>Sidewinder</strong> <strong>G2</strong> is configured for a different cluster mode, and the HA cluster will<br />

not function properly. If this happens, you will need to reboot each <strong>Sidewinder</strong><br />

<strong>G2</strong> to synchronize the HA cluster.<br />

Removing a <strong>Sidewinder</strong> <strong>G2</strong> from an HA cluster<br />

To remove a secondary/standby from an HA cluster, follow the steps below.<br />

1 Connect to the HA cluster and select High Availability in the Admin<br />

Console tree. The Common Parameters window appears.<br />

2 In the Pair Members table, highlight the secondary/standby and then click<br />

Delete.<br />

When the <strong>Sidewinder</strong> <strong>G2</strong> is removed from the HA cluster, it will automatically<br />

reboot and become a functioning stand-alone <strong>Sidewinder</strong> <strong>G2</strong>.<br />

You must remove the secondary/standby from the HA cluster before you can<br />

remove the primary from the HA cluster. Once you have removed the<br />

secondary/standby from an HA cluster, follow the steps below to remove the<br />

primary from the HA cluster:<br />

1 Connect to the HA cluster.<br />

2 Access the State Change Wizard by selecting the dashboard at the top <strong>of</strong><br />

the Admin Console tree and then clicking the Change link. The Welcome<br />

window appears.<br />

3 Click Next.<br />

4 Select Change To Standalone State, and then click Next.<br />

5 The State Change Summary window appears listing the actions that will be<br />

performed when you click Execute. To remove the primary from the HA<br />

cluster and return it to the standalone state, click Execute. The <strong>Sidewinder</strong><br />

<strong>G2</strong> will automatically reboot. Once the <strong>Sidewinder</strong> <strong>G2</strong> is rebooted, it will<br />

become a functioning standalone <strong>Sidewinder</strong> <strong>G2</strong>.<br />

To cancel the wizard without making any changes, click Cancel.<br />

Important: Once the <strong>Sidewinder</strong> <strong>G2</strong> has finished rebooting, the IP address in<br />

the Admin Console Connection window will still display the cluster common IP<br />

address. Before connecting to the standalone <strong>Sidewinder</strong> <strong>G2</strong>, you will need to<br />

manually change the IP address back to the <strong>Sidewinder</strong> <strong>G2</strong>’s individual<br />

address.<br />
