Updating Plugins; Destroying A Cluster; Cluster Troubleshooting - Aruba Networks PowerConnect W Clearpass 100 Software Deployment Manual

To check the current status of a node, log into that node and click the
the cluster status on the High Availability page. The node's current status is displayed under the Local
Status heading.
Use this procedure to make the current primary node the secondary node:
1. Log into the current secondary node of the cluster.
2. Click Cluster Maintenance, and then click the Swap Primary Server command link.
3. A progress meter is displayed while the primary node is switched. The cluster's virtual IP address will be
temporarily unavailable while the swap takes place.
4. The swap is complete. The secondary node is now the new primary node for the cluster. The cluster is
back in a fault-tolerant mode of operation.
5. Perform any required maintenance on the new secondary node.

Updating Plugins

Plugins cannot be updated while High Availability is running. Because exact synchronization of the two
servers is required for High Availability Services, you must first destroy the cluster, then re-create the
cluster after the plugins are updated. See
For information on updating plugins, see

Destroying a Cluster

The Destroy Cluster command link is used to shut down a cluster and return to independent nodes. Avoid
using this command when you are accessing the cluster using its virtual IP address, as the virtual IP address
will no longer be available when the cluster has been destroyed.
Immediately after the cluster is destroyed, both nodes will have the same database and configuration state.
However, changes on one node will no longer be replicated to the other node as the cluster is no longer
functioning.

Cluster Troubleshooting

When building a cluster, use the recommended values for the downtime threshold, keep-alive rate and
configuration sync rate. You should only change these values if you have a specific requirement and have
verified that different values can be used to meet that requirement.
