HA Clusters tab
The HA Clusters tab allows you to create and delete HA clusters, add encryption engines to and
remove encryption engines from HA clusters, and failback an engine.
The HA Clusters tab (Figure 274) is viewed from the Encryption Group Properties dialog box. To
access the HA Clusters tab, select a group from the Encryption Center Devices table, then select
Group > HA Clusters from the menu task bar, or right-click a group and select HA Clusters. The
Properties dialog box displays with the HA Clusters tab selected.
NOTE
You can also select a group from the Encryption Center Devices table, then click the Properties icon.
FIGURE 274 Encryption Group Properties dialog box - HA Clusters tab
HA clusters are groups of encryption engines that provide high availability features. If one of the
engines in the group fails or becomes unreachable, the other cluster member takes over the
encryption and decryption tasks of the failed encryption engine. An HA cluster consists of exactly
two encryption engines. See “Creating high availability (HA) clusters” on page 510.
For more information, refer to the following topics:
“Failback option” on page 512
“Invoking failback” on page 512
Link Keys tab
Connections between a switch and an NetApp LKM key vault require a shared link key. Link keys
are used only with LKM key vaults. They are used to protect data encryption keys in transit to and
from the key vault. There is a separate link key for each key vault for each switch. The link keys are
configured for a switch but are stored in the encryption engines, and all the encryption engines in a
group share the same link keys.
