Adding a new controller module to each cluster

You must add a new controller module to each site, creating an HA pair in each site. This is a multistep process involving both hardware and software changes that must be performed in the proper order at each site.

About this task

  • The new controller module must be received from NetApp as part of the upgrade kit.

    You should verify that PCIe cards in the new controller module are compatible and supported by the new controller module.

  • Your system must have an empty slot available for the new controller module when upgrading to a single-chassis HA pair (an HA pair in which both controller modules reside in the same chassis).

    Note This configuration is not supported on all systems. Platforms with single chassis configurations that are supported in ONTAP 9 are AFF A300, FAS8200, FAS8300, AFF A400, AFF80xx, FAS8020, FAS8060, FAS8080, and FAS9000.

  • You must have rack space and cables for the new controller module when upgrading to a dual-chassis HA pair (an HA pair in which the controller modules reside in separate chassis).

    Note This configuration is not supported on all systems.

  • You must connect each controller module to the management network through its e0a port or, if your system has one, you can connect to the e0M port as the management port.

  • These tasks must be repeated at each site.

  • The preexisting controller modules are referred to as the existing controller modules.

    The examples in this procedure have the console prompt existing_ctlr>.

  • The controller modules that are being added are referred to as the new controller modules; the examples in this procedure have the console prompt new_ctlr>.

  • This task uses the following workflow:
