Mount an SAP HANA scale-out backup as a standard mount

From the management console, you can mount images of an SAP HANA database as a standard mount or as a virtual database—application aware mount. This is the procedure for a standard mount. To make a virtual database—application aware mount—see the procedure in SAP HANA database virtual copy.

About standard mounts

A standard mount provides the backup image disk of data, active log and archive log volume to the specified target. You can mount snapshot backup images of an SAP HANA database as a standard mount for the following:

  • Any manual operation.
  • To run the SNAPSHOT DATA INTEGRITY CHECK: This tool runs the SAP HANA persistence checking tool, hdbpersdiag with the 'check all' option to verify the healthy state of data volumes from the mounted snapshot image. Mount jobs fail if there is any corruption during these checks.

Pre checks during mount

  • Connector connectivity status: The Backup and DR agent is installed and a secret is applied for host connectivity between the backup/recovery appliance and the Backup and DR agent.
  • Mount locations specified are available for mount operation.
  • HANA binary is installed.
  • Verify that the HANA sid same as source is not up and running on the target.
  • The HANA instance version is greater than 2.0SP05.
  • Permission check on source and target project for the cloud service.

Mount the database image as a standard mount

Use these instructions to mount the database image as a standard mount:

  1. In the management console App Manager, right-click the protected database from the App Manager Applications list, and select Access.

  2. Select a backup and choose Mount.

  3. On the Mount page, select the Project Name, Region, Zone, and GCE Instance Name.

  4. Optionally, enter a unique name associated with the mount in the Label field.

  5. Under Application Options, disable Create New Virtual Application.

    Included Tenant Databases is informational only, showing the list of tenant databases under the backup image.

  6. At Mapping Options, enter mount locations and select disk types for both the data volume and the logs.

  7. The Snapshot Data Integrity Check is by default set to true. This tool will run the SAP HANA persistence checking tool, hdbpersdiag API with 'check all' option. This will verify the healthy state of data and active log volumes from the mounted snapshot image. Mount jobs will fail with error for any corruption during these checks otherwise it will show success.

    The result of the Integrity check will be available under /var/act/log/(HANA sid)_dataintegrity_check.log and /usr/sap/GC1/HDB00/hana-scaleup-3/trace/localclient.*.trc./.

    If you don't want to run the check, set it to false by clicking the toggle button.

  8. Click Pre-Flight check. The Pre-Flight check validates the required options on the target server for a successful mount. Upon a successful pre-flight the Submit button is enabled. If the pre-flight check fails, you see what failed so you can correct it and rerun the pre-flight check.

  9. Click Submit. You can go to the Job Monitor to view the progress and details of the job. The mounted image is available in the Active Mounts.

Management of the active mounts

Once you have created a mount, you can track the image from the Backup and DR Service management console App Manager > Active Mounts. Ideally, don't leave any image mounted indefinitely. This is because the backup image that the mount was created from, cannot expire until all its mounts have been deleted. When you have finished using the mounted image then either:

  • Unmount the image. You can remount it if needed. You can then delete the image later when you are certain it is no longer needed.
  • Unmount and delete the image. This deletes the mounted image, not the backup that the mount is based on.
