Replacing the controller module
You must review the prerequisites for the replacement procedure and select the correct one for
your version of the ONTAP operating system.
Before you begin
• All drive shelves must be working properly.
• If your system is a FlexArray system or has a V_StorageAttach license, you must refer to the
additional required steps before performing this procedure.

• If your system is in an HA pair, the healthy node must be able to take over the node that is
being replaced (referred to in this procedure as the "impaired node").
• If your system is in a MetroCluster configuration, you must review the section
Choosing the
correct recovery procedure
to determine whether you should use this procedure.
If this is the procedure you should use, note that the controller replacement procedure for a
node in a four or eight node MetroCluster configuration is the same as that in an HA pair. No
MetroCluster-specific steps are required because the failure is restricted to an HA pair and
storage failover commands can be used to provide nondisruptive operation during the
replacement.
About this task
• This procedure includes steps for automatically or manually reassigning drives to the
replacement
node, depending on your system's configuration.
You should perform the drive reassignment as directed in the procedure.
• You must replace the failed component with a replacement FRU component you received from
your provider.
• You must be replacing 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 node to the replacement node so
that the replacement node will boot up in the same version of ONTAP as the old controller
module.
• Any PCIe cards moved from the old controller module to the new controller module or added
from existing customer site inventory must be supported by the replacement controller module.
NetApp Hardware Universe
• It is important that you apply the commands in these steps on the correct systems:
◦ The
impaired
node is the node that is being replaced.
◦ The
replacement
node is the new node that is replacing the impaired node.
◦ The
healthy
node is the surviving node.
• You must always capture the node's console output to a text file.
This provides you a record of the procedure so that you can troubleshoot any issues that you
might encounter during the replacement process.
