You may want to notify PI AF users that the PI AF server will be temporarily unavailable while it is being upgraded. Take the active PI AF server machine offline and pause the inactive PI AF server machines before you upgrade machines in a failover cluster. This prevents changes to the PI AF SQL Server database during the upgrade of the failover cluster.
-
Open the failover cluster tool for your operating system.
-
On the failover cluster machine that is active, select Roles in the left pane.
-
In the right pane right-click the AFSERVER role and select Stop Role.
-
For each of the non-active nodes in the failover cluster, right-click each node in the Nodes list and select Pause | Do Not Drain nodes. If that option is not available, select Pause.
Note: By pausing the non-active nodes, you ensure that the PI AF server resource does not fail over.
