Replacing the Kernel

The domain-based scheduling feature (hereinafter referred to as the feature) requires a specific kernel version. Therefore, you need to install a compatible OS kernel in advance. After the kernel is installed, you can use the built-in GRUB tool to change the default kernel boot entry, or use the iBMC remote management interface to replace the default kernel with the kernel that supports the feature.

Using the CLI

Download the kernel RPM package that supports the feature and upload it to the environment. Run the following command in the directory where the kernel RPM package is stored to install the kernel:

        
             rpm -ivh kernel-5.10.0-270.0.0.173.oe2203sp4.aarch64.rpm --force

Check the installed kernels and find the index of the kernel that supports the feature. Assume that the index is 0.
1

grubby --info=ALL | egrep -i 'index|title'
Replace the default kernel boot entry with index 0.
1

grubby --set-default-index=0
Check that the default kernel has been replaced with the kernel that supports the feature.
1

grubby --default-kernel
Reboot the server.
1

reboot

Using the iBMC

Download the kernel RPM package that supports the feature and upload it to the environment. Run the following command in the directory where the kernel RPM package is stored to install the kernel:

        
             rpm -ivh kernel-5.10.0-270.0.0.173.oe2203sp4.aarch64.rpm --force

Log in to the iBMC.
Open the remote virtual console.
Forcibly restart the machine.
Select the kernel that supports the feature and wait until the restart is complete.
