Resolving a system firmware boot failure

Learn how to identify the service action that is needed to resolve a failure while booting your system firmware.

Procedure

Does the baseboard management controller (BMC) respond to commands and are you able to access the BMC web interface?
Note: To determine whether the BMC responds to commands, run the following ipmitool command:
```
ipmitool -I lanplus -U <username> -P <password> -H <bmc ip or bmc hostname> chassis status
```
If Then

Yes: Continue with step 3.

No: Continue with the next step.
Complete the following actions, one at a time, until the problem is resolved:
1. Reset the BMC remotely by entering the following command:
```
ipmitool -I lanplus -U <username> -P <password> -H <bmc ip or bmc hostname> mc reset cold
```
2. Disconnect the power cords from the system for 30 seconds. Reconnect the power cords, wait 5 minutes, and then go to step 1.
3. Update the BMC firmware by using the pUpdate command with the block transfer (BT) option:
  1. Type mkdir /tmp/media and press Enter.
  2. Type the following command and press Enter:
    mount -t nfs xxx.xxx.xx.xx:/path/of/files /tmp/media, where xxx.xxx.xx.xx is the IP address of the system to which you want to establish the connection.
  3. Type cd /tmp/media and press Enter.
  4. To update the BMC firmware, type the following command and press Enter:
    ./pUpdate -f bmc.bin -i bt, where bmc.bin is the name of the BMC image file.
  5. Allow at least 2 minutes for the BMC to reboot.
4. Replace the system backplane.
  - If your system is a 5104-22C or 9006-22C, go to 5104-22C or 9006-22C locations to identify the physical location and the removal and replacement procedure.
  - If your system is a 9006-12P, go to 9006-12P locations to identify the physical location and the removal and replacement procedure.
  - If your system is a 9006-22P, go to 9006-22P locations to identify the physical location and the removal and replacement procedure.
This ends the procedure.
After you pressed the power button, did the system turn on but fail to display the Petitboot menu?

If Then

Yes: Continue with the next step.

No: This ends the procedure.
Complete the following actions, one at a time, until the problem is resolved:
1. Ensure that the TPM card is fully seated.
  - If your system is a 5104-22C or 9006-22C, go to 5104-22C or 9006-22C locations to identify the physical location.
  - If your system is a 9006-12P, go to 9006-12P locations to identify the physical location.
  - If your system is a 9006-22P, go to 9006-22P locations to identify the physical location.
2. Disconnect the power cords from the system for 30 seconds. Reconnect the power cords, wait 5 minutes, and then go to step 3.
3. Update the PNOR firmware. For instructions, see Getting fixes.
  Note: If your system is a 9006-12P or 9006-22P, the PNOR firmware level must be V2.12-20190404, or later.
4. Replace the system backplane.
  - If your system is a 5104-22C or 9006-22C, go to 5104-22C or 9006-22C locations to identify the physical location and the removal and replacement procedure.
  - If your system is a 9006-12P, go to 9006-12P locations to identify the physical location and the removal and replacement procedure.
  - If your system is a 9006-22P, go to 9006-22P locations to identify the physical location and the removal and replacement procedure.
This ends the procedure.

If	Then
Yes:	Continue with the next step.
No:	This ends the procedure.
