Hi Folks,

I am getting below error, please suggest me here. 

While deploying OCP cluster (4.9.9) on bare metal using UPI method for bootstrap node (Same error while doing with master nodes). Screenshot has been attached. (Let me know if any other details needed).

Regards,

I am getting the same exact error while installing 4.11. How did you resolve this?

[rocko]

run lsblk to check the device names on your systems to insure the device is named as you expect

I am facing the exact same issue. lsblk does show dhe device names correctly.

Maybe it's an issue with the rhcos image being used in the image-url. When I removed the --image-url option from the install command, the install succeeded with an image that coreos-installer, probably, downloaded.

Next I downloaded a new image from https://mirror.openshift.com/pub/openshift-v4/dependencies/rhcos/4.12/4.12.0/rhcos-4.12.0-x86_64-met... and used that with the --image-url. I was again able to proceed with the install.

Hope this helps.
