Before You Start #

How to Upgrade HPE ML Data Management #

1. Run a Preflight Check #

PachD has a preflight check mode that you can enable in your Helm chart by setting pachd.preflightchecks.enabled to true. Preflight checks run as a Kubernetes job, and can use a different version of HPE ML Data Management than the rest of the chart. In this case, you will set it to the version you are upgrading to (for example, the latest version is 2.7.4).

Example configuration:

preflightCheckJob:
    enabled: true
    image:
        tag: "2.7.4"

You’ll see a pod named pachyderm-preflight-check was created to perform the preflight checks.

  • If its status says completed, you are ready to continue with the upgrade.
  • If its status does not say completed, reach out to the HPE ML Data Management team for assistance with your upgrade.
