If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

Before issuing the oc describe nodes command, issue the oc login command. The oc get nodes command will return the list of nodes in your selected project, like this.

~]# oc get nodes
NAME                 STATUS    ROLES     AGE       VERSION
dev001-infra-4k6z9   Ready     infra     273d      v1.11.0+d4cacc0
dev001-master-0      Ready     master    273d      v1.11.0+d4cacc0
dev001-worker-5n4fj  Ready     worker    273d      v1.11.0+d4cacc0

The oc describe node <node name> command can be used to display the node events. In this example, the events for dev001-worker-5n4fj will be displayed.

oc describe node dev001-worker-5n4fj

Something like this should be returned.
