Steps
1.
If the controller to be serviced is not at the LOADER prompt, reboot the controller:
system node halt
-node node_name
After you issue the command, you should wait until the system stops at the LOADER prompt.
2. At the LOADER prompt, access the special drivers specifically designed for system-level diagnostics to
function properly:
boot_diags
3. Select Scan System from the displayed menu to enable running the diagnostics tests.
4. Select Test Memory from the displayed menu.
5. Proceed based on the result of the preceding step:
◦ If the test failed, correct the failure, and then rerun the test.
◦ If the test reported no failures, select Reboot from the menu to reboot the system.
Step 3: Return the failed part to NetApp
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the

Overview of controller module replacement - AFF A800
You must review the prerequisites for the replacement procedure and select the correct
one for your version of the ONTAP operating system.
• All drive shelves must be working properly.
• The healthy controller must be able to take over the controller that is being replaced (referred to in this
procedure as the “impaired controller”).
• 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.
• 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 controller to the replacement controller so
that the replacement controller 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 controller is the controller that is being replaced.
◦ The replacement controller is the new controller that is replacing the impaired controller.
◦ The healthy controller is the surviving controller.
• You must always capture the controller’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.
