Upgrade RHEL Host

If your RHEL host is unsupported, manually upgrade your RHEL host to the supported version.

Prerequisites

Verify that the RHEL host is supported. See Supported Hypervisor Upgrade Path.

RHEL requires the following dependencies for the LCP package and host components to work properly.

PyYAML, c-ares, libev, libunwind, libyaml, python-beaker, python-gevent, python-greenlet, python-mako, python-markupsafe, python-netaddr, python-paste, python-tempita

Procedure

1. Follow the instructions available on the RHEL web site to upgrade your host. Reboot the RHEL host host after the upgrade process has completed.
2. Restart the NSX agent.
   /etc/init.d/nsx-opsagent restart
3. Download the NSX kernel module for RHEL x.x.
4. Install the NSX kernel module.

   tar - xvf <path_to_kernel_module_file> 
   cd <folder_extracted_from_previous_step>
   sudo yum install *.rpm 
   rpm -qa | grep nsx
