Controller module
Overview of controller module replacement - AFF A200
You must review the prerequisites for the replacement procedure and select the correct
one for your version of the ONTAP operating system.
What you’ll need
• All drive shelves must be working properly.
• If your system is in an HA pair, the healthy controller must be able to take over the controller that is being
replaced (referred to in this procedure as the “impaired node”).
About this task
• You must replace the failed component with a replacement FRU component you received from your
provider.
• You must replace a controller module with a controller module of the same model type. You cannot
upgrade your system by just replacing the controller module.
• You cannot change any drives or drive shelves as part of this procedure.
• In this procedure, the boot device is moved from the impaired controller to the replacement node so that
the replacement node will boot up in the same version of ONTAP as the old controller module.
• It is important that you apply the commands in these steps on the correct systems:
◦ The impaired node is the controller that is being replaced.
◦ The replacement node is the new controller that is replacing the impaired controller.
◦ The healthy node is the surviving controller.
