High availability clusters

• The encryption engines that are part of an HA cluster must belong to the same encryption
group and be part of the same fabric.
• An HA cluster cannot span fabrics and it cannot provide failover/failback capability within a
fabric transparent to host MPIO software.
• HA cluster configuration and related operations must be performed on the group leader.
• HA clusters of FS8-18 blades should not include blades in the same DCX Backbone chassis.
NOTE
In Fabric OS 6.3.0 and later, HA cluster creation is blocked when encryption engines belonging
to FS8-18 blades in the same DCX Backbone chassis are specified.
• Cluster links must be configured before creating an HA cluster.
• It is recommended that the HA cluster configuration be completed before you configure
storage devices for encryption.
• It is mandatory that the two encryption engines in the HA cluster belong to two different nodes
for true redundancy. This is always true for Brocade Encryption Switchswitches, but is not true
if two FS8-18 blades in the same DCX Backbone chassis are configured in the same HA
cluster.
Creating HA clusters
For the initial encryption node, perform the following procedure.
1. Select Configure > Encryption from the menu task bar to display the Encryption Center
dialog box. (Refer to Figure 376 on page 976.)
2. Select an encryption group from the Encryption Center Devices table, then select Group >
HA Cluster from the menu task bar.
NOTE
If groups are not visible in the Encryption Center Devices table, select View > Groups from the
menu task bar.
The Encryption Group Properties dialog box displays, with the HA Clusters tab selected. (Refer
to
Figure 476 .)
3. Select an available encryption engine from the Non HA Encryption Engines table and a
destination HA cluster from the High Availability Clusters table. Select New HA Cluster if you are
creating a new cluster.
NOTE
If you are creating a new HA cluster, a dialog box displays requesting a name for the new HA
cluster. HA cluster names can have up to 31 characters. Letters, digits, and underscores are
allowed.
4. Click the right arrow to add the encryption engine to the selected HA cluster.
