Description of Problem:

  When I test on a Fujitsu iRMC server without a RAID controller, this will cause an error.
  In case of Fujitsu iRMC server, OCP always tries to clean current RAID setting during deployment.
  In this case, an error will occur if we try to clean against non-RAID server.
  And then, OCP deployment fails.

Version-Release number of selected component:

  Red Hat OpenShift Container Platform Version Number:4.8
  Release Number:4.8.0-0.nightly-2021-06-06-164529

Drivers or hardware or architecture dependency:

  Fujitsu iRMC

How reproducible:

  Always

Step to Reproduce:

  $ openshift-install --dir ~/clusterconfigs create manifests
  $ cp ~/ipi/99_router-replicas.yaml ~/clusterconfigs/openshift/
  $ openshift-install --dir ~/clusterconfigs --log-level debug create cluster

Actual Results:

  In case of iRMC, OCP always does delete_configuration clean step.
  This means that OCP cleans current RAID setting even if we don't set RAID via BareMetalHost.
  This cause unintentional loss of RAID settings.

Expected Results:

  Not clean current RAID setting if we don't set RAID via BareMetalHost.
  This means that we don't change current RAID setting in the servers and we use that.
