We have broughtup our helper node using centos7 . once helper nodes comes up configured vars.yaml file and main.yaml file ,ran ansible palybooks and successful. Created manifests and ignition configs sucessfuly and copied

cp ~/ocp4/*.ign /var/www/html/ignition/

restorecon -vR /var/www/html/

restorecon -vR /var/lib/tftpboot/

chmod o+r /var/www/html/ignition/*.ign

We are trying to bringup mixed mode setup (Both VM and 1 Physical BMS as compute node).We are trying to bring 3 master VM's , 2 worker vm's and 1 Physicl bms server as worker node

Master VM's -3 Woeker VM's -2 Physicl BMS as worker node -1

bootstarp,Master ,Worker vm's coming up fine. but we are facing issue while physical bms server brining up as worker node.

Physical BMS server boot option set as network boot , This sever able to do PXE boot up ,Get IP address from DHCP server ,able to down load RHCOS images and install it. But this process is repeating as loop in the server . Need help to fix this issue .

Am i missing any configuration ? Is there some configuration I need to handle from PXE server configuration end .which resides in Helper node ? Please help to fix the issue
