This topic explains the key guidelines and limitations for implementing High Availability (HA) in Cisco IoT FND solutions, including requirements for nodes, scripts, and service downtime expectations.
Zero service downtime is targeted by Cisco IoT FND HA, but it is not guaranteed.
-
Cisco IoT FND HA refers to FND server HA. HA for other Cisco IoT FND solution components like FAR, ASR, load balancer etc, has to be considered during design for Cisco IoT FND Solution HA.
-
All Cisco IoT FND nodes must on the same subnet.
-
All Cisco IoT FND nodes must run on similar hardware.
-
All Cisco IoT FND nodes must run the same software version.
-
Run the Cisco IoT FND setup script (/opt/cgms/bin/setupCgms.sh) on all the nodes.
-
Run the DB migration script (/opt/cgms/bin/db-migrate) on only one node.
-
The /opt/cgms/bin/print_cluster_view.sh script displays information about Cisco IoT FND cluster members.
