2 Viewing and editing group properties 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 46. The HA Clusters tab (Figure 51) allows you to create and delete HA clusters, add encryption engines to and remove encryption engines from HA clusters, and failback an engine. FIGURE 51 Encryption Group Properties - HA Clusters tab 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 45. 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 86. 86 Fabric OS Encryption Administrator's Guide 53-1001864-01
