Red Hat Enterprise Linux (RHEL)
NSP deployment on RHEL
The following topics define the operating system (OS) requirements for deploying an NSP cluster and optional NSP components.
RHEL version support
NSP Release 24.8 supports the following RHEL server x86-64 versions in a NSP cluster deployment:
Previous releases, or other variants of Red Hat, and other Linux variants are not supported.
Customers must ensure that NSP supports each update applied to RHEL OS in an NSP deployment. An automated update by a subscription manager may deploy an unsupported RHEL version. In order to prevent the accidental deployment of an unsupported RHEL version, Nokia recommends to lock the supported release in RHEL subscription manager.
For the latest compatibility information, see the Host Environment Compatibility Reference for NSP and CLM.
The Nokia-provided NSP RHEL OS image is based upon RHEL 8.10 and can only be used for the deployment of NSP software, and not for the deployment of any other Nokia or third-party product. VMs created from the Nokia-provided NSP RHEL OS image can only be updated with the Nokia-provided NSP RHEL OS update. The VSR-NRC is also compatible with RHEL 8.10, but relies on a separate software image that is provided among its installation files.
The RHEL OS must be installed in English.
The NSP does not necessarily support all functionality provided in RHEL. The NSP does not support the requiretty option in /etc/sudoers. The RHEL chronyd service is required as the time-synchronization mechanism on NSP cluster nodes. The NSP also requires that the server hostname is configured in the /etc/hosts file. RHEL must be installed in 64-bit mode where the NSP will be installed. The NSP product team does not support the configuration of OS services not enabled by default in the NSP RHEL OS image and/or required by NSP applications.
Nokia recommends installing any OS, driver, or firmware updates that the hardware vendor advises for RHEL.
With the exception of documented operating system parameter changes for NSP, all other settings must be left at the RHEL default configuration.
The NSP Installation and Upgrade Guide provides detailed instructions for the RHEL OS installation.
Red Hat support
For customers using the NSP RHEL OS image for NSP guest virtual machines, support for the RHEL instance is available directly from Nokia, not Red Hat. For all other RHEL installations, Red Hat support must be purchased for all platforms running the RHEL server with NSP. It is strongly recommended to purchase a support package from Red Hat that provides 24x7 support.
The NSP RHEL OS image can only be used as a guest VM hosting an NSP component, and not for the deployment of any other Nokia or third-party product.
Third-party applications
Applications that are not sanctioned by Nokia must not be running on any virtual instance running NSP components. Nokia reserves the right to remove any applications that are suspected of causing issues from stations running NSP components.
