Updating Sledgehammer

Periodically, the [drp-community-content]{.title-ref} will be updated with newer sledgehammer images. This is particularly true with the v4.5.0 and v4.6.0 releases, because Sledgehammer is updating from Centos 7 to Centos 8. This is sometimes referred as Sledge8 or SL8.

Also, sledgehammer will be updated with security fixes or other fixes that will also require an update.

This leads to: How do you update sledgehammer?

Solution

There are a couple of [drpcli]{.title-ref} commmands that can be used to help with this setup.

To update the default sledgehammer iso image, you can use this command:

drpcli bootenvs uploadiso sledgehammer

This will get the appropriate sledgehammer image. You can use the [-D]{.title-ref} parameter if an external http proxy is needed to access the internet.

Additionally, in the v4.6.0 release, profiles to choose different versions of sledgehammer are provided in the [drp-community-content]{.title-ref} pack. This will enable you to track a specific release version of sledgehammer. There will NOT be a profile per release, but a new profile will be added when a release adds a new sledgehammer.

These profiles use the Customization using bootenv-customize system to override the default sledgehammer. By adding one of these profile to the [global]{.title-ref} profile, the system will use that sledgehammer for all systems. Individual known systems can be overridden by applying the profile to the machine directly.

Some examples of these profiles are:

  • sledgehammer-centos8-v4.6.0 - Secure Boot capable Centos8-based sledgehammer
  • sledgehammer-centos7-v4.6.0 - Secure Boot capable Centos7-based sledgehammer
  • sledgehammer-centos7-v4.5.0 - Secure Boot capable Centos7-based sledgehammer (from the v4.5.0 release)
  • sledgehammer-centos8-full-v4.6.0 - Sledgehammer with more drivers (but not Secure Boot capable)

To help with iso downloading, the profile can be used to retrieve the iso with a command like this:

drpcli profiles uploadiso sledgehammer-centos8-full-v4.6.0
