Starting the cluster after shutdown

If the IBM Storage Scale cluster was shut down, start the cluster by using the following steps:

Ensure that the worker nodes are in Ready state before restart of the IBM Storage Scale cluster by entering the oc get nodes command. If any of the worker nodes are in a state other than Ready, the IBM Storage Scale cluster fails to restore.

1. Scale up the operator pods by setting the replicas in the deployment to 1.

   oc scale deployment ibm-spectrum-scale-controller-manager -n ibm-spectrum-scale-operator --replicas=1
   

   After the operator pod comes back up, the core pods are rescheduled and the default CSI label is reapplied.
