I am installing RDO via RDO-Manager on a set of IBM H-Chassis blades. I need to configure the networking to perform the IPMI operations and PXE boot the overcloud nodes. The problem I am trying to solve is to get the chassis AMM to correctly route the IPMI/PXE operations to the blades. The IBM chassis requires all IPMI networking to use a VLAN that has been specified as the Chassis Internal Network. I have installed the undercloud on on blade on CentOS 7 and have been able to interact with the AMM and the blade IMMs on a vlan. Where I am running into problems is when the undercloud configuration occurs I am no longer able to interact on the specified VLAN and lose access to the Chassis AMM.
On each blade I have 4 network ports. 2 1G and 2 10G network switches. I have installed CentOS on the undercloud and use 1 1G port as the management. I have specified a 10G switch as the PXE/Management network. In the undercloud.conf file the 10G port is the port I have specified as the local interface.
To use the IPMI interface it has to tag all packets with the Chassis Internal Network VLAN. Are there any configuration tips that I can follow?
