b. Rotate the locking latches upward, tilting them so that they clear the locking pins, and then lower them
into the locked position.
c. If you have not already done so, reinstall the cable management device.
d.
Interrupt the normal boot process by pressing
Ctrl-C.
Step 4: Run diagnostics
After you have replaced a component in your system, you should run diagnostic tests on that component.
Your system must be at the LOADER prompt to start diagnostics.
All commands in the diagnostic procedures are issued from the controller where the component is being
replaced.
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. Select NVDIMM Test from the displayed menu.
6. 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 5: Return the failed part to NetApp
After you replace the part, you can return the failed part to NetApp, as described in the RMA instructions
shipped with the kit. Contact technical support at
NetApp Support, 888-463-8277 (North America), 00-800-44-
638277 (Europe), or +800-800-80-800 (Asia/Pacific) if you need the RMA number or additional help with the
replacement procedure.
Replace the NVDIMM battery - AFF A800
To replace the NVDIMM battery, you must remove the controller module, remove the
battery, replace the battery, and then reinstall the controller module.
All other components in the system must be functioning properly; if not, you must contact technical support.
Step 1: Shut down the impaired controller
Shut down or take over the impaired controller using the appropriate procedure for your configuration.
Option 1: Most configurations
To shut down the impaired controller, you must determine the status of the controller and, if necessary, take
over the controller so that the healthy controller continues to serve data from the impaired controller storage.
