Description Luis Arizmendi 2020-02-20 14:38:00 UTC

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

Comment 3 Beth White 2020-05-28 12:07:29 UTC

This is not considered a release blocker for 4.5. Moving to 4.6.

Comment 5 Tomas Sedovic 2020-08-13 11:24:35 UTC

Moving to modified since the PR has been merged: https://github.com/openshift/installer/pull/3795
