Deploying Rapid Release Update with IUF

This procedure describes how to deploy a Rapid Release Update(RRU) to an operational CSM system using the Install and Upgrade Framework (IUF). It updates the operational CSM release with the CVE patches from csm-security product. The kernels of all the NCNs are updated using CFS to create new NCN images. NCNs are rebooted with the new image to complete the deployment.

This procedure is limited to the deployment of the new images to management nodes (NCNs) only.

Important: This procedure must be performed with IUF. Do not install the security RPMs manually or treat product delivery alone as completion. A kernel update is active on a node only after the node boots with the newly prepared image.

The deployment workflow comprises the following steps. Instructions should be executed in the order shown.

  1. Prepare for the install procedure and download product media
