Configuring HA<br />

To add an additional cluster member, see “Joining a <strong>Sidewinder</strong> <strong>G2</strong> to an<br />

existing HA cluster” on page 498.<br />

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

Joining a <strong>Sidewinder</strong> <strong>G2</strong> to an existing HA cluster, requires two steps:<br />

• Add a placeholder in the HA cluster for that <strong>Sidewinder</strong> <strong>G2</strong> in the High<br />

Availability Common Parameters window. See “Adding a placeholder in the<br />

HA cluster” on page 498.<br />

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

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

Note: You must have a dedicated heartbeat burb configured on each <strong>Sidewinder</strong><br />

<strong>G2</strong> that you register to an HA cluster. See “Configuring the heartbeat burbs” on<br />

page 493 for instructions.<br />

Adding a placeholder in the HA cluster<br />

Adding a <strong>Sidewinder</strong> <strong>G2</strong> to an HA cluster creates a placeholder for that<br />

<strong>Sidewinder</strong> <strong>G2</strong> within that HA cluster. Once you have added the <strong>Sidewinder</strong> <strong>G2</strong><br />

to the HA cluster, you will need to join the <strong>Sidewinder</strong> <strong>G2</strong> to the HA cluster<br />

using the State Change Wizard.<br />

To add a placeholder for the new <strong>Sidewinder</strong> <strong>G2</strong> in the existing HA cluster, do<br />

the following:<br />

1 Connect to the HA cluster using the Admin Console, and select High<br />

Availability in the Admin Console tree. The High Availability Common<br />

Parameters tab appears.<br />

2 In the Pair Members area, click New. The Add New Firewall window<br />

appears.<br />

3 In the Name field, enter the name <strong>of</strong> the <strong>Sidewinder</strong> <strong>G2</strong> you are adding the<br />

HA cluster.<br />

4 [Conditional] If you selected the Primary/Standby HA mode, in the Takeover<br />

Time field, select the number <strong>of</strong> seconds that the primary must be<br />

unavailable before the secondary/standby will begin the takeover process.<br />

The default value is 13 seconds.<br />

Note: This field does not appear if you selected peer-to-peer HA or loadsharing<br />

HA.<br />

5 In the IP Address in Heartbeat Burb field, enter the individual IP address (in<br />

the heartbeat burb) <strong>of</strong> the <strong>Sidewinder</strong> <strong>G2</strong> that you are adding to the HA<br />

cluster.
