In order to test IPv6 deployment on Dell hardware I was in need to patch the servers to ensure that UEFI boot mode is in use.
Normally I would have use the DSU that runs from within Linux, but as the servers are part of an OpenShift installation (using baremetal-deploy) and using CoreOS as the underlying system I wanted to load ISO from HTTP server on the deployhost
(running RHEL).
The command is not that hard, let’s first define some variables:
1 2 3 4 |
|
Now, let’s attach the ISO file:
1 |
|
Once done, we should check status with:
1 |
|
Once finished, let’s disconnect:
1 |
|
And then, verify the status again:
1 |

Hope It’s useful for you!
