CAUTION Service Disruption

An NSP system installation requires a thorough understanding of NSP system administration and platform requirements, and is supported only under the conditions described in this guide, the NSP Planning Guide, and the NSP Release Notice.

Such an operation must be planned, documented, and tested in advance on a trial system that is representative of the target live network. Contact NSP professional services to assess the requirements of your NSP deployment, and for information about the upgrade service, which you are strongly recommended to engage for any type of deployment.

The following scenarios support the initial deployment of NSP clusters:

• NSP system installation that does not include legacy NSP components; see New NSP system deployment

• migration from a legacy independent NFM-P deployment to a deployment that includes NSP clusters; see Migration from independent NFM-P

For all scenarios, an external DNS server must accept requests from Kubernetes. If the server rejects requests, memory issues may occur.

Note: Before you attempt an NSP installation, ensure that any third-party software installed on the NSP deployer host or any NSP cluster VM is disabled and stopped.

Note: Check Alerts before you attempt an NSP installation.

A completely new NSP system deployment, sometimes called a greenfield deployment, includes only new NSP components. Such a scenario is described in Pathway for new NSP system deployment, which provides a comprehensive view of the installation activities for planning purposes. The pathway includes links to NSP installation procedures.

Licensing

Your NSP system requires a license. You must contact Nokia after installation with the CLM UUID file to obtain the license. To install your NSP license, see “How do I install the NSP license?” in the NSP System Administrator Guide.

DR system installation

To install an NSP cluster describes the installation of one NSP cluster. To install a DR NSP system, you must perform the procedure once in each data center, as described in Pathway for new NSP system deployment.

Note: In a DR deployment, the first data center in which you perform To install an NSP cluster is designated the primary data center and hosts the active nspOs instance after the installation.

If you have an independent NFM-P system that you want to include in a greenfield NSP deployment, you can transfer the nspOS functions of the NFM-P deployment to the new NSP system.

See To migrate from an independent NFM-P system to an NSP cluster deployment for information.
