that they clear the locking pins, gently push the controller all the way in, and then lower the locking
latches into the locked position.
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to
interrupt the boot process.
d. If you have not already done so, reinstall the cable management device.
e. Interrupt the normal boot process and boot to LOADER by pressing
Ctrl-C
.
If your system stops at the boot menu, select the option to boot to LOADER.
f. At the LOADER prompt, enter
bye
to reinitialize the PCIe cards and other components.
g. Interrupt the boot process and boot to the LOADER prompt by pressing
Ctrl-C
.
If your system stops at the boot menu, select the option to boot to LOADER.
Step 5: 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 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 to run diagnostics tests.
5. Proceed based on the result of the preceding step:
◦
If the scan show problems, correct the issue, and then rerun the scan.
◦
If the scan 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.
Steps
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.
