Configure certificates for PI AF high availability in a failover cluster

Before you begin, make sure that the PI AF Application Service has been installed and verified on each cluster that you want to include in the collective.

Complete the steps in this section if the machine that you will use to for the PI AF Application Service will:

• connect to the AF SQL Server database on the SQL Server failover cluster, and

• is in a PI AF collective.

If this PI AF server that includes the PI AF Application Service will be a member of a PI AF collective, each computer in the failover cluster that must use the same Windows certificate that supports communication with the PI AF Application Service that used in the failover cluster.

1. Copy the AF server certificate, named AFServer.pfx and located in the C:\ProgramData\OSIsoft\AF directory, from the active node in the failover cluster to the same location on other machines in the failover cluster.

2. Use the cluster administration tool for your operating system to restart the PI AF Application Service on each machine in the failover cluster.

   • Windows Server 2008 R2: In the Failover Cluster Management snap-in, right-click the service and select Move this service or application to another node > Move to node <name of non-active node>.
