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 6: Restore the controller module to operation after running diagnostics

After completing diagnostics, you must recable the system, give back the controller
module, and then reenable automatic giveback.

1. Recable the system, as needed.

If you removed the media converters (QSFPs or SFPs), remember to reinstall them if you are using fiber
optic cables.

2. Return the node to normal operation by giving back its storage: 

storage failover giveback

-ofnode 

impaired_node_name

3. If automatic giveback was disabled, reenable it: 

storage failover modify -node local -auto

-giveback true

Step 7: Switch back aggregates in a two-node MetroCluster configuration

After you have completed the FRU replacement in a two-node MetroCluster
configuration, you can perform the MetroCluster switchback operation. This returns the
configuration to its normal operating state, with the sync-source storage virtual machines
(SVMs) on the formerly impaired site now active and serving data from the local disk
pools.

This task only applies to two-node MetroCluster configurations.

Steps

1. Verify that all nodes are in the 

enabled

 state: 

metrocluster node show
