IPMI | VMM bare metal builds

A couple of tips when investigating VMM bare-metal IPMI issues
The VMM jobs will report the following if the connection failed:

Error 21212: Connecting to the BMC with address x.x.x.x failed.

This error indicates a problem with network connectivity, likely a firewall or routing issue (most IPMI communications go over port 623 UDP)

Error 21220: An out of band operation (IPMI) for the BMC x.x.x.x failed IPMI completion code 0x9 – Invalid Role.

This error indicates a problem with authentication. Check the VMM Run-As account, the username must have exactly the same case as the IPMI username. Also check the permissions required are sufficient (Full Admin Permissions are usually required)
