The procedure ensures that IBM Storage Fusion HCI System is brought up to the most recent version.
Note: Follow the sequence mentioned in this procedure.

Procedure

  1. Upgrade IBM Storage Fusion HCI System management software.
    If you are on 2.7.x and want to upgrade to 2.8.x, see Upgrading IBM Storage Fusion HCI System management software. For procedure to upgrade IBM Storage Fusion HCI System with disaster recover setup, see Upgrading a disaster recovery setup.
  2. Upgrade the storage service. For more information about upgrade, see Upgrading IBM Storage Fusion HCI System services.
  3. Upgrade the Backup & Restore service. For more information about the steps to upgrade, see Upgrading IBM Storage Fusion HCI System services.
  4. Upgrade the Data Cataloging service. For more information about the steps to upgrade, see Upgrading IBM Storage Fusion HCI System services.
  5. Optionally, if you want to upgrade OpenShift Container Platform, see OpenShift Container Platform upgrade. For more information about Red Hat OpenShift Container Platform, see product documentation Red Hat OpenShift Container Platform or Red Hat OpenShift Container Platform.
    Note:
