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 501.

The HA Clusters tab (Figure 190) allows you to create and delete HA clusters, add encryption

engines to and remove encryption engines from HA clusters, and failback an engine.

Engine Operations tab

The Engine Operations tab (Figure 191) enables you to replace an encryption engine in an

encryption switch with another encryption engine in another switch within a DEK Cluster

environment. A DEK Cluster is a set of encryption engines that encrypt the same target storage

device. DEK Clusters do not display in the Management application, they are an internal

implementation feature and have no user-configurable properties.

NOTE

You cannot replace an encryption engine if it is part of an HA Cluster. For information about HA

Clusters, refer to “HA Clusters tab” on page 483.
