Preface Red Hat OpenShift Data Foundation supports deployment on existing Red Hat OpenShift Container Platform (RHOCP) IBM Z clusters in connected or disconnected environments along with out-of-the-box support for proxy environments. Note See Planning your deployment and Preparing to deploy OpenShift Data Foundation for more information about deployment requirements. To deploy OpenShift Data Foundation, follow the appropriate deployment process for your environment: Internal Attached Devices mode Deploy using local storage devices External mode Chapter 1. Preparing to deploy OpenShift Data Foundation When you deploy OpenShift Data Foundation on OpenShift Container Platform using local storage devices, you can create internal cluster resources. This approach internally provisions base services and all applications can access additional storage classes. Before you begin the deployment of Red Hat OpenShift Data Foundation using local storage, ensure that your resource requirements are met. See requirements for installing OpenShift Data Foundation using local storage devices . On the external key management system (KMS), When the Token authentication method is selected for encryption then refer to Enabling cluster-wide encryption with the Token authentication using KMS . Ensure that you are using signed certificates on your Vault servers. After you have addressed the above, follow these steps in the order given: Install the Red Hat OpenShift Data Foundation Operator . Install Local Storage Operator . Find the available storage devices . Create the OpenShift Data Foundation cluster service on IBM Z . 1.1. Requirements for installing OpenShift Data Foundation using local storage devices Node requirements The cluster must consist of at least three OpenShift Container Platform worker or infrastructure nodes with locally attached-storage devices on each of them. Each of the three selected nodes must have at least one raw block device available. OpenShift Data Foundation uses the one or more available raw block devices. Note Make sure that the devices have a unique by-id device name for each available raw block device. The devices you use must be empty, the disks must not include Physical Volumes (PVs), Volume Groups (VGs), or Logical Volumes (LVs) remaining on the disk. For more information, see the Resource requirements section in the Planning guide . 1.2. Enabling cluster-wide encryption with KMS using the Token authentication method You can enable the key value backend path and policy in the vault for token authentication. Prerequisites Administrator access to the vault. A valid Red Hat OpenShift Data Foundation Advanced subscription. For more information, see the knowledgebase article on OpenShift Data Foundation subscriptions . Carefully, select a unique path name as the backend path that follows the naming convention since you cannot change it later. Procedure Enable the Key/Value (KV) backend path in the vault. For vault KV secret engine API, version 1: For vault KV secret engine API, version 2: Create a policy to restrict the users to perform a write or delete operation on the secret: Create a token that matches the above policy: Chapter 2. Deploy OpenShift Data Foundation using local storage devices Deploying OpenShift Data Foundation on OpenShift Container Platform using local storage devices provides you with the option to create internal cluster resources. Follow this deployment method to use local storage to back persistent volumes for your OpenShift Container Platform applications. Use this section to deploy OpenShift Data Foundation on IBM Z infrastructure where OpenShift Container Platform is already installed. 2.1. Installing Red Hat OpenShift Data Foundation Operator You can install Red Hat OpenShift Data Foundation Operator using the Red Hat OpenShift Container Platform Operator Hub. Prerequisites Access to an OpenShift Container Platform cluster using an account with cluster-admin and operator installation permissions. You must have at least three worker or infrastructure nodes in the Red Hat OpenShift Container Platform cluster. For additional resource requirements, see the Planning your deployment guide. Important When you need to override the cluster-wide default node selector for OpenShift Data Foundation, you can use the following command to specify a blank node selector for the openshift-storage namespace (create openshift-storage namespace in this case): Taint a node as infra to ensure only Red Hat OpenShift Data Foundation resources are scheduled on that node. This helps you save on subscription costs. For more information, see the How to use dedicated worker nodes for Red Hat OpenShift Data Foundation section in the Managing and Allocating Storage Resources guide. Procedure Log in to the OpenShift Web Console. Click Operators -> OperatorHub . Scroll or type OpenShift Data Foundation into the Filter by keyword box to find the OpenShift Data Foundation Operator. Click Install . Set the following options on the Install Operator page: Update Channel as stable-4.18 . Installation Mode as A specific namespace on the cluster . Installed Namespace as Operator recommended namespace openshift-storage . If Namespace openshift-storage does not exist, it is created during the operator installation. 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 select 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 plugin . Click Install . Verification steps 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. In the Web Console: Navigate to Installed Operators and verify that the OpenShift Data Foundation Operator shows a green tick indicating successful installation. Navigate to Storage and verify if the Data Foundation dashboard is available. 2.2. Installing Local Storage Operator Install the Local Storage Operator from the Operator Hub before creating Red Hat OpenShift Data Foundation clusters on local storage devices. Procedure Log in to the OpenShift Web Console. Click Operators -> OperatorHub . Type local storage in the Filter by keyword box to find the Local Storage Operator from the list of operators, and click on it. Set the following options on the Install Operator page: Update channel as stable . Installation mode as A specific namespace on the cluster . Installed Namespace as Operator recommended namespace openshift-local-storage . Update approval as Automatic . Click Install . Verification steps Verify that the Local Storage Operator shows a green tick indicating successful installation. 2.3. Finding available storage devices (optional) This step is additional information and can be skipped as the disks are automatically discovered during storage cluster creation. Use this procedure to identify the device names for each of the three or more worker nodes that you have labeled with the OpenShift Data Foundation label cluster.ocs.openshift.io/openshift-storage='' before creating Persistent Volumes (PV) for IBM Z. Procedure List and verify the name of the worker nodes with the OpenShift Data Foundation label. Example output: Log in to each worker node that is used for OpenShift Data Foundation resources and find the unique by-id device name for each available raw block device. Example output: In this example, for bmworker01 , the available local device is sdb . Identify the unique ID for each of the devices selected in Step 2. In the above example, the ID for the local device sdb Repeat the above step to identify the device ID for all the other nodes that have the storage devices to be used by OpenShift Data Foundation. See this Knowledge Base article for more details. 2.4. Enabling DASD devices If you are using DASD devices, you must enable them before creating an OpenShift Data Foundation cluster on IBM Z. Once the DASD devices are available to z/VM guests, complete the following steps from the compute or infrastructure node on which an OpenShift Data Foundation storage node is being installed. Procedure To enable the DASD device, run the following command: 1 For <device_bus_id>, specify the ID of the DASD device bus-ID. For example, 0.0.b100 . To verify the status of the DASD device you can use the the lsdasd and lsblk commands. To low-level format the device and specify the disk name, run the following command: 1 For <device_name>, specify the disk name. For example, dasdb . Important The use of DASD quick-formatting Extent Space Efficient (ESE) DASD is not supported on OpenShift Data Foundation. If you are using ESE DASDs, make sure to disable quick-formatting with the --mode=full parameter. To auto-create one partition using the whole disk, run the following command: 1 For <device_name>, enter the disk name you have specified in the step. For example, dasdb . Once these steps are completed, the device is available during OpenShift Data Foundation deployment as /dev/dasdb1 . Important During LocalVolumeSet creation, make sure to select only the Part option as device type. Additional resources For details on the commands, see Commands for Linux on IBM Z in IBM documentation. 2.5. Creating OpenShift Data Foundation cluster on IBM Z Use this procedure to create an OpenShift Data Foundation cluster on IBM Z. Prerequisites Ensure that all the requirements in the Requirements for installing OpenShift Data Foundation using local storage devices section are met.

Choose one of the following: Disks on all nodes Uses the available disks that match the selected filters on all the nodes. Disks on selected nodes Uses the available disks that match the selected filters only on the selected nodes. Important The flexible scaling feature is enabled only when the storage cluster that you created with three or more nodes are spread across fewer than the minimum requirement of three availability zones. For information about flexible scaling, see knowledgebase article on Scaling OpenShift Data Foundation cluster using YAML when flexible scaling is enabled . Flexible scaling features get enabled at the time of deployment and can not be enabled or disabled later on. If the nodes selected do not match the OpenShift Data Foundation cluster requirement of an aggregated 30 CPUs and 72 GiB of RAM, a minimal cluster is deployed. For minimum starting node requirements, see the Resource requirements section in the Planning guide. From the available list of Disk Type , select SSD/NVME . Expand the Advanced section and set the following options: Volume Mode Block is selected by default. Device Type Select one or more device type from the dropdown list. By default, Disk and Part options are included in the Device Type field. Note For a multi-path device, select the Mpath option from the drop-down exclusively. For a DASD-based cluster, ensure that only the Part option is included in the Device Type and remove the Disk option. Disk Size Set a minimum size of 100GB for the device and maximum available size of the device that needs to be included. Maximum Disks Limit This indicates the maximum number of PVs that can be created on a node. If this field is left empty, then PVs are created for all the available disks on the matching nodes.

Uninstalling OpenShift Data Foundation in Internal-attached devices mode Use the steps in this section to uninstall OpenShift Data Foundation. Uninstall Annotations Annotations on the Storage Cluster are used to change the behavior of the uninstall process. To define the uninstall behavior, the following two annotations have been introduced in the storage cluster: uninstall.ocs.openshift.io/cleanup-policy: delete uninstall.ocs.openshift.io/mode: graceful The following table provides information on the different values that can used with these annotations: Table 7.1. uninstall.ocs.openshift.io uninstall annotations descriptions Annotation Value Default Behavior cleanup-policy delete Yes Rook cleans up the physical drives and the DataDirHostPath cleanup-policy retain No Rook does not clean up the physical drives and the DataDirHostPath mode graceful Yes Rook and NooBaa pauses the uninstall process until the administrator/user removes the Persistent Volume Claims (PVCs) and Object Bucket Claims (OBCs) mode forced No Rook and NooBaa proceeds with uninstall even if the PVCs/OBCs provisioned using Rook and NooBaa exist respectively Edit the value of the annotation to change the cleanup policy or the uninstall mode. Expected output for both commands: Prerequisites Ensure that the OpenShift Data Foundation cluster is in a healthy state. The uninstall process can fail when some of the pods are not terminated successfully due to insufficient resources or nodes. In case the cluster is in an unhealthy state, contact Red Hat Customer Support before uninstalling OpenShift Data Foundation. Ensure that applications are not consuming persistent volume claims (PVCs) or object bucket claims (OBCs) using the storage classes provided by OpenShift Data Foundation. If any custom resources (such as custom storage classes, cephblockpools) were created by the admin, they must be deleted by the admin after removing the resources which consumed them. Procedure Delete the volume snapshots that are using OpenShift Data Foundation. List the volume snapshots from all the namespaces. From the output of the command, identify and delete the volume snapshots that are using OpenShift Data Foundation. <VOLUME-SNAPSHOT-NAME> Is the name of the volume snapshot <NAMESPACE> Is the project namespace Delete PVCs and OBCs that are using OpenShift Data Foundation. In the default uninstall mode (graceful), the uninstaller waits till all the PVCs and OBCs that use OpenShift Data Foundation are deleted. If you want to delete the Storage Cluster without deleting the PVCs, you can set the uninstall mode annotation to forced and skip this step. Doing so results in orphan PVCs and OBCs in the system. Delete OpenShift Container Platform monitoring stack PVCs using OpenShift Data Foundation. See Removing monitoring stack from OpenShift Data Foundation Delete OpenShift Container Platform Registry PVCs using OpenShift Data Foundation. Removing OpenShift Container Platform registry from OpenShift Data Foundation Delete OpenShift Container Platform logging PVCs using OpenShift Data Foundation. Removing the cluster logging operator from OpenShift Data Foundation Delete the other PVCs and OBCs provisioned using OpenShift Data Foundation. Given below is a sample script to identify the PVCs and OBCs provisioned using OpenShift Data Foundation. The script ignores the PVCs that are used internally by OpenShift Data Foundation. Note Omit RGW_PROVISIONER for cloud platforms. Delete the OBCs. <obc-name> Is the name of the OBC <project-name> Is the name of the project Delete the PVCs. <pvc-name> Is the name of the PVC <project-name> Is the name of the project Note Ensure that you have removed any custom backing stores, bucket classes, etc., created in the cluster. Delete the Storage System object and wait for the removal of the associated resources. Check the cleanup pods if the uninstall.ocs.openshift.io/cleanup-policy was set to delete (default) and ensure that their status is Completed . Example output: Confirm that the directory /var/lib/rook is now empty. This directory is empty only if the uninstall.ocs.openshift.io/cleanup-policy annotation was set to delete (default). If encryption was enabled at the time of install, remove dm-crypt managed device-mapper mapping from the OSDs on all the OpenShift Data Foundation nodes. Create a debug pod and chroot to the host on the storage node. <node-name> Is the name of the node Get Device names and make note of the OpenShift Data Foundation devices. Example output: Remove the mapped device. Important If the above command gets stuck due to insufficient privileges, run the following commands: Press CTRL+Z to exit the above command. Find PID of the process which was stuck. Terminate the process using kill command. <PID> Is the process ID Verify that the device name is removed. Delete the namespace and wait till the deletion is complete. You need to switch to another project if openshift-storage is the active project. For example: The project is deleted if the following command returns a NotFound error. Note While uninstalling OpenShift Data Foundation, if namespace is not deleted completely and remains in Terminating state, perform the steps in Troubleshooting and deleting remaining resources during Uninstall to identify objects that are blocking the namespace from being terminated. Delete local storage operator configurations if you have deployed OpenShift Data Foundation using local storage devices. See Removing local storage operator configurations . Unlabel the storage nodes. Remove the OpenShift Data Foundation taint if the nodes were tainted. Confirm all the Persistent volumes (PVs) provisioned using OpenShift Data Foundation are deleted. If there is any PV left in the Released state, delete it. <pv-name> Is the name of the PV Remove the CustomResourceDefinitions . To ensure that OpenShift Data Foundation is uninstalled completely, on the OpenShift Container Platform Web Console, Click Storage . Verify that OpenShift Data Foundation no longer appears under Storage. 7.1.1. Removing local storage operator configurations Use the instructions in this section only if you have deployed OpenShift Data Foundation using local storage devices. Note For OpenShift Data Foundation deployments only using localvolume resources, go directly to step 8. Procedure Identify the LocalVolumeSet and the corresponding StorageClassName being used by OpenShift Data Foundation. Set the variable SC to the StorageClass providing the LocalVolumeSet . List and note the devices to be cleaned up later. Inorder to list the device ids of the disks, follow the procedure mentioned here, See Find the available storage devices . Example output: Delete the LocalVolumeSet . Delete the local storage PVs for the given StorageClassName . Delete the StorageClassName . Delete the symlinks created by the LocalVolumeSet . Delete LocalVolumeDiscovery . Remove the LocalVolume resources (if any). Use the following steps to remove the LocalVolume resources that were used to provision PVs in the current or OpenShift Data Foundation version. Also, ensure that these resources are not being used by other tenants on the cluster. For each of the local volumes, do the following: Identify the LocalVolume and the corresponding StorageClassName being used by OpenShift Data Foundation. Set the variable LV to the name of the LocalVolume and variable SC to the name of the StorageClass For example: List and note the devices to be cleaned up later. Example output: Delete the local volume resource. Delete the remaining PVs and StorageClasses if they exist. Clean up the artifacts from the storage nodes for that resource. Example output: Wipe the disks for each of the local volumesets or local volumes listed in step 1 and 8 respectively so that they can be reused. List the storage nodes. Example output: Obtain the node console and execute chroot /host command when the prompt appears. Store the disk paths in the DISKS variable within quotes. For the list of disk paths, see step 3 and step 8.c for local volumeset and local volume respectively. Example output: Run sgdisk --zap-all on all the disks. Example output: Exit the shell and repeat for the other nodes. Delete the openshift-local-storage namespace and wait till the deletion is complete. You will need to switch to another project if the openshift-local-storage namespace is the active project. For example: The project is deleted if the following command returns a NotFound error. 7.2. Removing monitoring stack from OpenShift Data Foundation Use this section to clean up the monitoring stack from OpenShift Data Foundation. The Persistent Volume Claims (PVCs) that are created as a part of configuring the monitoring stack are in the openshift-monitoring namespace. Prerequisites PVCs are configured to use the OpenShift Container Platform monitoring stack. For more information, see configuring monitoring stack . Procedure List the pods and PVCs that are currently running in the openshift-monitoring namespace. Example output: Edit the monitoring configmap . Remove any config sections that reference the OpenShift Data Foundation storage classes as shown in the following example and save it. Before editing After editing In this example, alertmanagerMain and prometheusK8s monitoring components are using the OpenShift Data Foundation PVCs. Delete the relevant PVCs. Make sure you delete all the PVCs that are consuming the storage classes. <pvc-name> Is the name of the PVC 7.3. Removing OpenShift Container Platform registry from OpenShift Data Foundation Use this section to clean up the OpenShift Container Platform registry from OpenShift Data Foundation. If you want to configure an alternative storage, see Image registry . The Persistent Volume Claims (PVCs) that are created as a part of configuring the OpenShift Container Platform registry are in the openshift-image-registry namespace. Prerequisites The image registry must have been configured to use an OpenShift Data Foundation PVC. Procedure Edit the configs.imageregistry.operator.openshift.io object and remove the content in the storage section. Before editing After editing In this example, the PVC is called registry-cephfs-rwx-pvc , which is now safe to delete. Delete the PVC. <pvc-name> Is the name of the PVC 7.4. Removing the cluster logging operator from OpenShift Data Foundation Use this section to clean up the cluster logging operator from OpenShift Data Foundation. The Persistent Volume Claims (PVCs) that are created as a part of configuring the cluster logging operator are in the openshift-logging namespace. Prerequisites The cluster logging instance should have been configured to use the OpenShift Data Foundation PVCs. Procedure Remove the ClusterLogging instance in the namespace. The PVCs in the openshift-logging namespace are now safe to delete. Delete the PVCs. <pvc-name> Is the name of the PVC
