Performing Scheduled Maintenance - Aruba Networks PowerConnect W Clearpass 100 Software Deployment Manual

This procedure assumes that the primary node has failed and has been replaced.
1. Configure the network settings, subscription IDs and hostname for the replacement
primary node.
2. Ensure that the replacement primary node and the secondary node are both online.
3. Log into the secondary node. (Due to fail-over, this node will be assigned the cluster's
virtual IP address.)
4. Click Cluster Maintenance, and then click the Destroy Cluster command link.
5. A progress meter is displayed while the cluster is destroyed.
NOTE
The virtual IP address of the cluster will be unavailable until the cluster is reinitialized.
6. Click the Create New Cluster command link.
7. Recreate the cluster using the process described in section 3. Note that the new
cluster's primary node must be the former cluster's secondary node that you are
presently logged into.
8. When the cluster is initialized, the database and configuration is replicated to the
replacement primary node.
9. Recovery is complete. The cluster's virtual IP address is now available, and the
secondary node is now the new primary node for the cluster. The cluster is back in a
fault-tolerant mode of operation.
A similar procedure can be used to rebuild the cluster in the event of a secondary node
suffering a hardware failure.

Performing scheduled maintenance

Routine maintenance tasks such as a server reboot or shutdown may occasionally be
required for a server that is part of a cluster.
These tasks may be performed by ensuring that the server is the secondary node in the
cluster. If the secondary node goes offline, the primary node will be unaffected and the
cluster will continue to provide network services without interruption. When the
secondary node comes back online, the cluster will be automatically rebuilt and
replication will resume.
To check the current status of a node, log into that node and click the
link displayed with the cluster status on the High Availability page. The node's current
status is displayed under the Local Status heading.
