Running diagnostics

After you have replaced the NVDIMM in your system, you should run diagnostic tests on that component.

Before you begin

Your system must be at the LOADER prompt to start diagnostics.

About this task

All commands in the diagnostic procedures are issued from the node where the component is being replaced.

Steps

  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.
  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.
