Gracefully Shutdown of a baremetal node configured with machineset in RHCOP 4

Solution Verified - Updated -

Environment

  • Red Hat OpenShift Container Platform (RHOCP)
    • 4
  • IPI/Baremetal

Issue

  • On shutting down a node on baremetal it gets powered on automatically by BareMetalHost using iDrac.

Resolution

  • Whenever a reboot or power off is triggered for a node the OpenShift Container Platform logs into the integrated Dell Remote Access Controller (iDrac) and issues a delete of the job queue.
  • To prevent the management of the number of Machine objects that matches the number of available BareMetalHost objects, add baremetalhost.metal3.io/detached annotation to the MachineSet object.
$ oc annotate machineset <machineset> -n openshift-machine-api 'baremetalhost.metal3.io/detached=''

  • If this does not work try to annotate the BareMetalHost.

  • First remove the label for MachineSet.

$ oc annotate machineset <machineset> -n openshift-machine-api baremetalhost.metal3.io/detached-''
  • Annotate the BareMetalHost.
$ oc annotate BareMetalHost <host name> baremetalhost.metal3.io/detached=''
