Creating node inventory

Once the servers are provisioned, a list of reachable nodes can be fetched using the below command:

ansible-playbook post_provision.yml

This creates a node inventory in /opt/omnia.

cat /opt/omnia/node_inventory
10.5.0.100 service_tag=XXXXXXX operating_system=RedHat
10.5.0.101 service_tag=XXXXXXX operating_system=RedHat
10.5.0.102 service_tag=XXXXXXX operating_system=Rocky
10.5.0.103 service_tag=XXXXXXX operating_system=Rocky

To create an inventory when Building Clusters, use the reachable nodes’ IP addresses from the above output to assign manager, compute and login groups. For more information on the inventory file used, click here.
