Installing IBM Storage Fusion Data Foundation Operator

Before you begin

Ensure that you have access to an OpenShift Container Platform cluster with a cluster-admin account and Operator installation permissions.
You must have at least four worker nodes that are evenly distributed across two data centers in the Red Hat OpenShift Container Platform cluster.
For more resource requirements, see Planning your deployment.

Important:

To override the default cluster-wide node selector for Fusion Data Foundation, you can use the following command in command-line interface to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case):
```
oc annotate namespace openshift-storage openshift.io/node-selector=
```
Taint a node as infra to ensure only IBM Storage Fusion Data Foundation resources are scheduled on that node. This helps you save on subscription costs. For more information, see How to use dedicated worker nodes for Fusion Data Foundation chapter in the Managing and Allocating Storage Resources guide.

You can install Fusion Data Foundation Operator by using the Red Hat OpenShift Container Platform Operator Hub.

Log in to the OpenShift Web Console.
Click Operators > OperatorHub.
Scroll or type Fusion Data Foundation into the Filter by keyword box to search for the Fusion Data Foundation Operator.
Click Install.
Set the following options on the Install Operator page:
1. Update Channel as stable-4.15.
2. Installation Mode as A specific namespace on the cluster.
3. Installed Namespace as Operator recommended namespace openshift-storage. If Namespace openshift-storage does not exist, it is created during the operator installation.
4. Select Approval Strategy as Automatic or Manual.
  
  If you select Automatic updates, then the Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without any intervention.
  
  If you selected Manual updates, then the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to update the Operator to a newer version.
Ensure that the Enable option is selected for the Console plug-in.
Click Install.
Verification steps
1. After the operator is successfully installed, a pop-up with a message, Web console update is available appears on the user interface. Click Refresh web console from this pop-up for the console changes to reflect.
2. Navigate to Installed Operators and verify that the Fusion Data Foundation Operator shows a green tick indicating successful installation.
3. Navigate to Storage and verify if the Data Foundation dashboard is available.
