How do I perform an NSP DR switchover?

CAUTION

Service disruption

Performing this procedure causes a temporary loss of network visibility, which may be service-affecting.

You must perform the procedure only with the assistance of technical support during a scheduled maintenance period.

Perform this procedure to manually switch the primary and standby NSP cluster roles.

Note: You require root user privileges on the NSP cluster host in each data center.

Note: A leading # character in a command line represents the root user prompt, and is not to be included in a typed command.


1	Perform How do I identify the NSP cluster DR roles? to identify each NSP cluster role.
2	Log in as the root user on a VM in the standby NSP cluster.
3	Open a console window.
4	Enter the following: `#` `kubectl exec -n $(kubectl get pods -A \| awk '/nsp-role-manager/ {print $1;exit}') -it $(kubectl get pods -A \| awk '/nsp-role-manager/ {print $2;exit}') -c role-manager -- /opt/nsp/os/rolemgr/bin/rmgrctl toActive ↵` The standby cluster assumes the primary role.
5	Enter the following periodically to display the status of the clusters as the roles change: `#` `kubectl exec -n $(kubectl get pods -A \| awk '/nsp-role-manager/ {print $1;exit}') -it $(kubectl get pods -A \| awk '/nsp-role-manager/ {print $2;exit}') -c role-manager -- /opt/nsp/os/rolemgr/bin/rmgrctl statusAll ↵` Output like the following is displayed when the role changes are complete: `Site: primary_cluster_name` `Status: active` `Since: timestamp` `Site: standby_cluster_name` `Status: standby` `Since: timestamp`
6	When the role changes are complete, close the open console windows. End of steps
