After OCP4.19 cluster is deployed by dev-script, scale up the cluster with one bare metal host that has sriov card on it. However, Bare Metal Operator (BMO) report error as below, and deploying new BMH fails. This issue blocks running sriov test operator scripts.

DoD:

• Make sure that  (BMO) is up and running.
• Make sure that connectivity is working by testing ping. The switch config should have vlan configured for control node host and the new BMH.
• Upgraded the idrac firmware to the latest version
• Tried different protocols, including ipmi, redfish, idrac-virtualmedia+https
• opened a ticket with Dell, uploaded the error messages.
• Tried to use curl command to simulate the communication between BMO and idrac, and it works.
