NOTE:This stage is only necessary if CSM v1.0.10 has not yet been installed (i.e. upgrading from v1.0.1 directly to v1.0.11).
Instruct Kubernetes to gracefully restart the Unbound pods:
ncn-m001:~ # kubectl -n services rollout restart deployment cray-dns-unbound
deployment.apps/cray-dns-unbound restarted
ncn-m001:~ # kubectl -n services rollout status deployment cray-dns-unbound
