@anurajpd Please confirm if you provided MDM values in the Powerflex CR under initContainers section.

If you are adding initContainers section in the CR, please provided MDM values as below:

initContainers:
  - image: docker.io/dellemc/sdc:4.5.2.1
    imagePullPolicy: IfNotPresent
    name: sdc
    envs:
      - name: MDM
        value: "10.xx.xx.xx,10.xx.xx.xx"  # provide MDM value

If you don't want to provide MDM details, please skip the initContainers section so that it picks from the default configuration.

[anurajpd]

The MDM value is already provided in the secret, so don't want to provide the same information at multiple places but need to change the sdc init container image repository, so just override that only.
