All containers hosted by the current engine (Engine list) are replaced by the new engine

Creating high availability (HA) clusters

A high availability (HA) cluster is a group of exactly two encryption engines. One encryption engine

can take over encryption and decryption tasks for the other encryption engine, if that member fails

or becomes unreachable.

When creating a new HA Cluster, add one engine to create the cluster and then add the second

engine. You can make multiple changes to the HA Clusters list; the changes are not applied to the

switch until you click OK.

Both engines in an HA cluster must be in the same fabric as well as the same encryption group.

NOTE

An IP address is required for the management port for any cluster-related operations.

1. Select Configure > Encryption from the menu bar.

The Encryption Center dialog box displays.

2. If groups are not visible in the Encryption Devices table, select View > Groups from the menu

bar.

The encryption groups display in the Encryption Devices table.

3. Select an encryption group from the tree, and select Group > HA Cluster from the menu bar, or

right-click the encryption group and select HA Cluster.

Encryption Group Properties are displayed, with the HA Clusters tab selected (Figure 235).

Available encryption engines are listed under Non-HA Encryption Engines.
