Red Hat Enterprise Linux (RHEL)
NSP deployment on RHEL
The following topics define the OS requirements for deploying an NSP cluster and optional NSP components.
RHEL version support
NSP Release 23.11 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.
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 8.8 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 rpms from the Nokia provided OS patch bundle. The VSR-NRC is also compatible with RHEL 8.8 but relies on a separate software image that is provided among its installation files.
The RHEL operating system must be installed as English.
The NSP does not necessarily support all functionality provided in RHEL. Network Manager is not supported in NSP deployments. The NSP does not support 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 NSP will be installed. The NSP product team does not support 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.
NFM-P RHEL support
NFM-P is supported on Red Hat Enterprise Linux (RHEL) 8, Server Edition x86-64. Previous releases or other variants of Red Hat and other Linux variants are not supported.
NFM-P Release 23.11 supports the following base RHEL versions:
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 8.8 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 rpms from the Nokia provided OS patch bundle.
The Red Hat Linux support of NFM-P is applicable to specific x86 Intel platforms provided by HP and Nokia only, for bare metal installations, where some systems may require specific updates of the RHEL operating system. See Red Hat’s Hardware Certification list on their website. NFM-P does not necessarily support all functionality provided in RHEL 8.
NFM-P supports the use of the RHEL Logical Volume Manager (LVM) on all server types and is limited to the resizing of logical volumes only. To ensure that disk throughput and latency of the resized volume remains consistent, the procedure for testing NFM-P disk performance in the NSP System Administrator Guide must be followed.
The RHEL operating system must be installed in 64-bit mode where NFM-P software will be installed.
The NFM-P server, NFM-P auxiliary collector, NSP Flow Collector, NSP Flow Collector Controller, NFM-P auxiliary database, NSP analytics server, NFM-P client delegate server, and NFM-P database RHEL operating system must be installed in English.
Nokia recommends installing any OS, driver, or firmware updates that the hardware vendor advises for RHEL.
With the exception of NFM-P documented Operating System parameter changes, all other settings must be left at the RHEL default configuration.
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 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.
