Chapter 6 Cisco SME Key Management High Availability Key Management Center Send documentation comments to [email protected] The default setting is Yes. Setting this option to No is required only if tape cloning is done outside of the Cisco SME tape group. High Availability Key Management Center The Cisco KMC server consists of a pair of KMC servers (KMS) that provides high availability and reliability. These high availability servers helps to avoid both downtime and loss of data through synchronization and redundancy. The KMS consists of a primary and a secondary KMC server which point to the same database. Both the KMS should use the same Oracle 11g Enterprise installation to achieve high availability. The Oracle 11g Enterprise installation should be installed on the two servers and synchronized using Oracle Active Data guard. Each Cisco SME cluster is configured with primary and secondary KMC servers. The primary server is preferred over the secondary server. The cluster is connected to the primary server and, at any indication of failure, connects to the secondary server. The cluster periodically checks for the availability of the primary server and resumes connection to the primary server when it becomes available. All the switches in a cluster use the same KMC server. When a switch connects to a secondary server, an automatic cluster-wide failover occurs to the secondary server. The switches in the cluster fails over to the primary server once it is available. Note Configure the primary and secondary servers during the cluster creation or update the Key Manager Settings for a created cluster. Choosing High Availability Settings To choose the primary or secondary server, follow these steps: Step 1 Step 2 Step 3 Go to the Fabric Manager Web Client and choose Key Manager Settings. In the High Availability Settings area, click Edit HA Settings. Choose the server to be the primary server and specify the IP address of the secondary server. Alternately, you can choose the server to be the secondary server and specify the IP address of the primary server.
