Red Screen of Panic while booting RHCOS 4.x node post installation.

Solution Verified - Updated -

Issue

  • The nodes are baremetal BFS and when they were built via ISO via HPE iLO, the ISO showed up as /dev/sda whereas the boot LUN showed up as /dev/sdb and therefore the command sudo coreos-installer install --copy-network --ignition-url=http://xxx.xxx.xxx.xxx/worker.ign /dev/sdb --insecure-ignition was executed. Now when the node reboots without an ISO inserted into the iLO RHCOS panics.
  • The workaround is to insert an ISO into the iLO while reboot and select the boot device as RHCOS node.
  • How can one fix it without workaround?

Environment
