Worker node configuration

Applying Machine Config Operator (MCO) settings

The following MachineConfiguration is provided as a convenience to easily change the following configuration:

• Kernel development and kernel header packages

  Install the kernel-related packages for IBM Storage Scale to successfully build its portability layer.

• Increase vmalloc kernel parameter

  Modify the kernel parameters that are needed to operate properly with Red Hat CoreOS. This applies only to the IBM Storage Scale running on Linux™ on Z.

Apply the correct sample file based on your OpenShift Container Platform version and machine architecture.
