update-initramfs -u equivalent

Hi all,
I have a long boot time with my suse. The cause of the long boot is my Samsung DVD drive.

exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata1.00: failed command: IDENTIFY PACKET DEVICE

I have found a solution https://paulphilippov.com/articles/how-to-fix-slow-boot-with-ata-errors
What is the equivalent of
sudo update-initramfs -u
so that I can apply the above solution?

I thank you a lot.

P.S. My suse is opensuse 13.2

It’s:

sudo mkinitrd
