1. If the node to be serviced is not at the LOADER prompt, reboot the node:
system node halt -node
node_name
After you issue the command, you should wait until the system stops at the LOADER prompt.

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.
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
