Upgrade only CSM through IUF

This option describes how to upgrade Cray Systems Management (CSM) software on a CSM-only system using IUF.

Upgrade only CSM through IUF

Description

The upgrade from CSM 1.5 to CSM 1.6 uses the IUF framework. The CSM upgrade steps are run automatically, either directly through IUF stages or by running a hook at the beginning or end of an IUF stage. The hooks that are run for the CSM upgrade are described in the description of CSM upgrade hooks section of the Upgrade CSM and additional products with IUF page.

Upgrade Procedure

  1. CSM preparation

    Read the Important Notes section of the CSM 1.5.0 or later to 1.6.0 Upgrade Process documentation and then follow only these CSM instructions in order:

    1. Prepare for Upgrade

  2. Prepare for the upgrade procedure and download product media

    1. Follow the IUF Prepare for the install or upgrade instructions to set environment variables used during the upgrade process.

    2. Download the desired HPE product media defined by the HPC CSM Software Recipe to ${MEDIA_DIR}, which was defined in the previous step.

  3. Product delivery

    NOTE The CSM upgrade prerequisites are automatically executed in a hook run before pre-install-check.

    Follow the IUF Product delivery instructions.

  4. Image preparation

    Follow the IUF Image preparation instructions.

  5. Management rollout

    NOTE The upgrade of CSM services and validation of CSM health occur automatically in a hook executed before the first management node is rolled out.

    Follow the IUF Management rollout instructions.

  6. Deploy product

    NOTE The application of networking changes and CoreDNS anti-affinity changes along with the upgrade of the Kubernetes control plane is performed in a hook automatically executed after deploy-product.

    Follow these IUF instructions in order:

    1. Deploy product
    2. Validate deployment

The IUF upgrade workflow is now complete. Exit any typescript sessions created during the upgrade procedure and remove any installation artifacts, if desired.
