HA Clusters tab

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 541.
The HA Clusters tab (Figure 262) 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 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. Refer to "Replacing an encryption engine in an encryption group" on
page 540.
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 584.
