Replacing the Kernel

The network multipathing feature requires a specific kernel version. Therefore, you need to install a kernel that supports network multipathing in advance.

Using the CLI

Download the RPM package of the kernel with the network multipathing feature to the target environment and run the following command in the directory where the kernel RPM package is located to install it:

        
             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 with network multipathing. Assume that the index is 0.
1

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

grubby --set-default-index=0
Check and confirm that the default kernel has been replaced with the kernel with network multipathing.
1

grubby --default-kernel
Reboot.
1

reboot
