How do I change NSP system addressing?

CAUTION

Service Disruption

Changing an IP address or hostname in an NSP system is a complex operation that requires careful planning and organization, and may require a complete system redeployment.

Do not attempt to modify the network configuration of an NSP component without assistance from NSP professional services.

Changing the addressing of the NSP deployer host or NSP cluster members may be required, for example, when the management network topology changes.

The requirements of such an operation depend on the management network topology and other considerations, so must be planned, co-ordinated, and performed only under the guidance of technical support.

Note: In-service hostname modification on an NSP deployer host or NSP cluster member is not possible. Such a modification requires a complete system reinstallation, and a reimport of the Helm charts and container images. Contact NSP technical support for more information.

Steps
 
1 

Collect the following information:

  • each NSP deployer host, NSP cluster, and ancillary component hostname

  • each NSP deployer host, NSP cluster, and ancillary component IP address

  • configuration information for mechanisms in the management network that affect addressing, such as NAT

  • each proposed new IP address or hostname

2 

Contact NSP professional services to plan and schedule a maintenance period for the addressing change.
