[Rdo-list] [RDO-Manager] IBM H-Chassis install bare metal

Thanks for responding.

That part I understand and have that working right.  The issue I am having is configuring RDO Manager/Ironic to work.  

In the undercloud.conf file, you specify the local interface.  This seems to be used for both PXE boot and IPMI operations.  When the undercloud is installed, the networking is not being configured correctly.  If the tagged interface isn't set up correctly, I lose access to the AMM and subsequently the IMM of the individual blade.

If I could get Ironic to not perform the IPMI operations and I have to reboot manually, that would be fine but I don't seem to see how to do that in the documentation.

If I understand it correctly you could set up the undercloud 1G port as trunk, use untagged frames for management and tagged for the Chassis Internal Network VLAN.

Here are some instructions to set up a vlan tagged interface:
