Deploy the first SAP HANA host using application volume group for SAP HANA

  • Article

All deployments start with the volumes for a single SAP HANA host. This is the case even for large, multiple-host installations. The shared, log-backup, and data-backup volumes will be created only for the first host. All other hosts in a multiple-host environment will share these volumes, and they will add only data and log volumes for each additional host.

This article describes how to deploy the first SAP HANA host using Azure NetApp Files application volume group for SAP HANA.

Before you begin

You should understand the requirements and considerations for application volume group for SAP HANA.

Be sure to follow the pinning recommendations and have at least one HANA VM in the availability set started.

Steps

  1. From your NetApp account, select Application volume groups, and click +Add Group.

  2. In Deployment Type, select SAP HANA and click Next.

  3. In the SAP HANA tab, provide HANA-specific information:

    • SAP ID (SID):
      The three alphanumeric-character SAP HANA system identifier.
    • Group name: The volume group name. For a multiple-host SAP HANA system, each host will create its own group. Because you are creating the first host, the group name starts with 'Name-proposal'-00001.
    • SAP node memory:
      This value defines the size of the SAP HANA database on the host. It is used to calculate the required volume size and throughput.
    • Capacity overhead (%):
      When you use snapshots for data protection, you need to plan for extra capacity. This field will add an additional size (%) for the data volume.
      You can estimate this value by using "change rate per day" X "number of days retention".
    • Single-host:
      Select this option for an SAP HANA single-host system or the first host for a multiple-host system. Only the shared, log-backup, and data-backup volumes will be created with the first host.
    • Multiple-host: Select this option for adding additional hosts to a multiple-hosts HANA system.

    Click Next: Volume Group.

  4. In the Volume group tab, provide information for creating the volume group:

    • Proximity placement group (PPG):
      Specifies that the data, log, and shared volumes are to be created close to the VMs.
    • Capacity pool:
      All volumes will be placed in a single manual QoS capacity pool.
      If you want to create the log-backup and data-backup volumes in a separate capacity pool, you can choose not to add those volumes to the volume group.
    • Virtual network:
      Specify an existing VNet where the VMs are placed.
    • Subnet:
      Specify the delegated subnet where the IP addresses for the NFS exports will be created. Ensure that you have a delegated subnet with enough free IP addresses.

    Click Next: Tag.

  5. In the Tags section of the Volume Group tab, you can add tags as needed for the volumes.

    Click Next: Protocol.

    Screenshot that shows how to add tags.

  6. In the Protocols section of the Volume Group tab, you can modify the Export Policy, which should be common to all volumes.

    Click Next: Volumes.

    Screenshot that shows the protocols tags.

  7. The Volumes tab summarizes the volumes that are being created with proposed volume name, quota, and throughput.

    The Volumes tab also shows that only the data, log, and shared volumes will be created close to the HANA VMs. The other volumes (data-backup and log-backup) are created at a different location within the region.

    The creation for the data-backup and log-backup volumes is optional.

    Screenshot that shows a list of volumes being created.

  8. In the Volumes tab, you can select each volume to view or change the volume details. For example, select "data-volume-name".

    Not all settings can be changed because of SAP HANA certification restrictions.

    When you select a volume, you can change the following values in the Basics tab:

    • Volume Name:
      It is recommended that you retain the suggested naming conventions.
    • Quota:
      The size of the volume.
    • Throughput:
      You can reduce the throughput requirements for development or test systems accordingly to the value required for your use cases.

    Click Next: Protocols to review the protocol settings.

    Screenshot that shows the Basics tab of Create a Volume Group page.

  9. In the Protocols tab of a volume, you can modify File path (the export name where the volume can be mounted) and Export policy as needed.

    You cannot change the protocol for the data and log volumes.

    Click the Tags tab if you want to specify tags for a volume. Or click Volumes to return to the Volumes overview page.

    Screenshot that shows the Protocol tab of Create a Volume Group page.

  10. The Volumes page displays volume details.

    Screenshot that shows Volumes page with volume details.

    If you want to remove the optional volumes (marked with a *) such as data-backup volume or log-backup volume from the volume group, select the volume and click Remove volume. Confirm the removal in the dialog box that appears.

    Important

    You cannot add a removed volume back to the volume group again.

    Screenshot that shows how to remove a volume.

    Click Volumes to return to the Volume overview page. Click Next: Review + create.

  11. The Review + Create tab lists all the volumes and how they will be created. Click Create Volume Group to start the volume group creation.

    Screenshot that shows the Review and Create tab.

  12. The Volume Groups deployment workflow starts, and the progress is displayed. This process can take a few minutes to complete.

    Screenshot that shows the Deployment in Progress window.

    You can display the list of volume groups to see the new volume group. You can select the new volume group to see the details and status of each of the volumes being created.

    Creating a volume group is an "all-or-none" operation. If one volume cannot be created, all remaining volumes will be removed as well.
