This content describes how to upgrade storage controllers in a HA pair while keeping all the existing data and disks. This is a complex procedure that should be used only by experienced administrators.

Use this procedure under the following circumstances:

  • You are performing one of the following controller upgrades:

    Old controller Replacement controller

    AFF A220 configured as an ASA

    ASA A150

    AFF A220, AFF A200, or AFF C190

    AFF A150

    FAS2620 or FAS2720

    FAS2820

    AFF A700 configured as an ASA

    ASA A900

    AFF A700

    AFF A900

    FAS9000

    FAS9500

  • You have verified with your NetApp sales representative that you have received the hardware for your controller upgrade:

    • ASA A150, AFF A150, or FAS2820 controller

    • ASA A900, AFF A900, or FAS9500 controller and NVRAM modules and the parts required for the upgrade

  • You are running the minimum ONTAP version for your upgrade. For more information, see Overview.

  • You do not want to add the new controllers as a new HA pair to the cluster and migrate the data by using volume moves.

  • You are experienced in administering ONTAP and are comfortable with the risks of working in diagnostic privilege mode.

Do NOT use this procedure under the following circumstances:

  • You are using FlexArray Virtualization Software on the AFF A700 or FAS9000 systems.

  • You are using a shared switch for cluster-interconnect and Ethernet attached storage.

For upgrading Fabric MetroCluster or MetroCluster IP configurations on AFF A700 or FAS9000 systems, see References to link to the MetroCluster Upgrade and Expansion content.

Note You can use NetApp Storage Encryption (NSE), NetApp Volume Encryption (NVE), and NetApp Aggregate Encryption (NAE) with this procedure.

If you prefer a different method of upgrading the controller hardware and are willing to do volume moves, refer to References to link to Upgrade by moving volumes or storage.
