Chapter 2. Verifying OpenShift Container Storage deployment for Internal-attached devices mode
Use this section to verify that OpenShift Container Storage is deployed correctly.
2.1. Verifying the state of the pods
To determine if OpenShift Container storage is deployed successfully, you can verify that the pods are in
- Click Workloads → Pods from the left pane of the OpenShift Web Console.
Select openshift-storage from the Project drop down list.
For more information on the expected number of pods for each component and how it varies depending on the number of nodes, see Table 2.1, “Pods corresponding to OpenShift Container storage cluster”.
Verify that the following pods are in running and completed state by clicking on the Running and the Completed tabs:

2.2. Verifying the OpenShift Container Storage cluster is healthy
- Click Home → Overview from the left pane of the OpenShift Web Console and click Persistent Storage tab.
In the Status card, verify that OCS Cluster and Data Resiliency has a green tick mark as shown in the following image:
Figure 2.1. Health status card in Persistent Storage Overview Dashboard
In the Details card, verify that the cluster information is displayed as follows:
- Service Name
- OpenShift Container Storage
- Cluster Name
For more information on the health of OpenShift Container Storage cluster using the persistent storage dashboard, see Monitoring OpenShift Container Storage.
2.3. Verifying that the OpenShift Container Storage specific storage classes exist
To verify the storage classes exists in the cluster:
- Click Storage → Storage Classes from the left pane of the OpenShift Web Console.
Verify that the following storage classes are created with the OpenShift Container Storage cluster creation:
