Configuring HA<br />

6 In the Registration Key field, create the registration key for this HA cluster.<br />

The key must be at least one character long and may consist <strong>of</strong><br />

alphanumeric characters, hyphens (-), and underscores (_).<br />

Important: You will need the registration key when you join the <strong>Sidewinder</strong> <strong>G2</strong><br />

to the HA cluster using the State Change Wizard.<br />

7 Click Add to add the <strong>Sidewinder</strong> <strong>G2</strong> to the HA cluster. You can now join the<br />

<strong>Sidewinder</strong> <strong>G2</strong> to the HA cluster using the State Change Wizard. See<br />

“Joining a <strong>Sidewinder</strong> <strong>G2</strong> to an existing HA cluster” on page 499.<br />

Joining a <strong>Sidewinder</strong> <strong>G2</strong> to an existing HA cluster<br />

To join a <strong>Sidewinder</strong> <strong>G2</strong> to an existing HA cluster, follow the steps below.<br />

Note: You must add a placeholder for the <strong>Sidewinder</strong> <strong>G2</strong> in the HA cluster before<br />

you will be able to join the HA cluster. See “Adding a placeholder in the HA cluster”<br />

on page 498.<br />

1 Connect to the <strong>Sidewinder</strong> <strong>G2</strong> that will be joining the HA cluster using the<br />

Admin Console.<br />

2 In the toolbar, click to launch the State Change Wizard. (You can also<br />

3<br />

access the State Change Wizard by selecting the dashboard and then<br />

clicking the Change link.) The Welcome window appears.<br />

Click Next.<br />

4 Select Not Enterprise Managed and click Next.<br />

5 Select HA Cluster and click Next.<br />

6 Select Join Existing HA Cluster and click Next.<br />

7 In the Gathering information to join cluster window, configure the following<br />

fields:<br />

• Partner’s Heartbeat Burb IP Address—Enter the heartbeat IP address<br />

<strong>of</strong> the HA partner.<br />

Important:This is the actual heartbeat IP address for the HA partner, not the<br />

cluster common heartbeat IP address.<br />

• Cluster Member Name—Enter the name <strong>of</strong> the <strong>Sidewinder</strong> <strong>G2</strong> that you<br />

are joining to the HA cluster (the name you entered when you added<br />

this <strong>Sidewinder</strong> <strong>G2</strong> to the HA cluster).<br />

• Registration Key—Enter the registration key for the HA cluster (the key<br />

that you created when you added this <strong>Sidewinder</strong> <strong>G2</strong> to the HA cluster<br />

in step 6 on page 499).<br />

8 Click Next. The State Change Summary window displays a list <strong>of</strong> the<br />

actions that will be performed when you click Execute.<br />

Important: The <strong>Sidewinder</strong> <strong>G2</strong> will be rebooted after the transition process is<br />

complete. Carefully review the changes before you click Execute, as changes<br />

you make after executing the state change will require an additional reboot.<br />
