About local storage and integrated storage controllers

  • HPE OneView is not aware of existing local storage configuration in the integrated storage controller unless you import the local storage when applying a server profile to the server hardware.

  • If you are using an NVMe-enabled backplane, you must use a SAS mezzanine controller to manage the internal drive bays. You cannot use the integrated storage controller.

  • The import option does not guarantee that no data will be lost. For example, if the server is currently in HBA mode, you must change it to RAID mode before it can be imported, and that change in controller mode can cause data loss.

  • Once you create a logical drive and apply it to server hardware, that logical drive can no longer be modified.

    NOTE:

    For controllers that support mixed mode (Gen10 servers), creating a logical drive uses the physical drives that are currently visible to the operating system. To preserve any data, back up the server drives before creating a logical drive.

While deleting or unassigning a server profile does not directly delete local storage data from the server hardware, data can be lost if a server profile that contains changes to the local storage configuration is applied to the server hardware in the future. The table below describes how to preserve your data when making profile or hardware changes.

Make a change to server hardware/server profile and preserve integrated local storage data

Change in server hardware

Procedure

Result

Move server profile from one server hardware to another

Move physical drives to new server hardware

  1. Unassign server profile from the current server hardware.

  2. Physically remove the local storage drives from the server hardware.

  3. Insert the local drives into new server hardware.

  4. Do not select Re-initialize internal storage when you apply the server profile to the new server hardware.

  • The appliance verifies that the physical drives have been inserted correctly by validating the saved unique identifier.

Assign a server profile to server hardware that has local storage configured

A. Import existing drives and data

  1. Delete or unassign the current server profile.

  2. Select Import existing logical drives when applying the new server profile.

  • The unique identifier is preserved.

  • The existing logical drives and data are imported.

B. Back up and copy data

  1. Back up data.

  2. Delete or unassign the server profile.

  3. Select Re-initialize internal storage when applying the new server profile.

  4. Copy the backed-up data to the new logical drive on the server hardware.

  • A new logical drive is created with a new unique identifier.

  • The backed-up data is copied to the new logical drive.

NOTE:

Gen9 and prior servers are incompatible with Gen10 servers because they do not utilize mixed mode. Therefore, when moving a server profile from a Gen10 server to a Gen9 server, you will need to reconfigure the local storage configuration based on the Gen9 integrated and/or mezzanine storage controller options.
