Description of problem: While installing OpenShift Baremetal IPI we can choose the NIC used by the control plane to provision the nodes but we cannot choose anything related to disks in the install-config.yaml: https://github.com/openshift/installer/blob/master/pkg/types/baremetal/platform.go It would be nice to be able to choose one of the (possible) multiple disks present in the physical nodes instead of asking for a single disk/RAID or just using the first available drive. It would be even better if that configuration could be done on a per-node or group of nodes basis.
Patch posted upstream of a possible solution https://github.com/openshift/installer/pull/3348
This is not considered a release blocker for 4.5. Moving to 4.6.
