System Settings, Defaults, Clusters, and Active Directory Authentication / Configuring and Managing Clusters |
The following procedure summarizes the steps in an initial Vocera Voice Server cluster configuration.
To set up a Vocera cluster:
If you do not need to add other nodes to the cluster, click Add to save changes, close the Add/Edit Cluster Server dialog box, and display the Cluster Setup page.
If you need to add any other nodes to the cluster, click Add & Continue to save the information and leave the Add/Edit Cluster Server dialog box open, then add another node.
When you are finished, the server list displays the IP address of each server you added along with any descriptions you entered. The Status column for each new server displays “Unsaved”.
The Status column for the current server displays “Active”.
The Status column for each additional server displays “Unknown”.
The cluster discovers the status of these unknown servers after you configure them for clustering and restart them.
The Status column for the current server displays “Active”.
The Status column for the server you want to use as the initial active server displays “Unknown”.
Vocera logs you out of current server’s Administration Console, and the current server restarts as a standby node in the cluster. If you copied a customized Properties.txt file to each standby, the Vocera Voice Server loads it when it restarts.
After you save this setting, the Vocera Voice Server populates the Server IP Address field with a comma-separated list of all cluster IP addresses. The Vocera Voice Server maintains this list if cluster nodes are added or removed.
Log in to the Administration Console of the active Vocera Voice Server. Make sure each server shows up in the list on the Cluster Setup page with the proper status of “active” or “standby”.
Fail over cluster control several times, until you confirm that the cluster behaves as you expect. See the Vocera Voice Server Installation Guide.
