Huawei MA5800-X15 MPLA Active/Standby failure after config load

  Rewarded Hi-coins: 0 (problem resolved)

I have 2 Huawei MA5800-X15 OLTs with 2 H902MPLA boards each, one on my desk and one working in production.

Initially, both boards of the OLT on my desk were running fine. One of the boards had ACT led ON and the RUN/ALM led was blinking 

green (0.5s) on both of the boards, as it should be when things are running correctly.


I've exported the config from the production OLT via tftp running:


   backup configuration tftp 192.168.1.11 backup.cfg


After that I've loaded and applied this configuration into the OLT on my desk using:


    load configuration tftp 192.168.1.11 backup.cfg all

    active configuration system


After that, OLT on my desk has rebooted successfully and loaded new configuration. Next I run save command.

Then I decided to reboot the active board (board1) with:


     reboot active


During the reboot of board1 the ACT led on board2 has switched ON (green) and the RUN/ALM led on board1 started blinking red 

every 0.25 sec, which is normal during reboot. Unfortunately the board2's RUN/ALM led never became green again and ACT led 

has never blinked again. I left everything for a couple of days and nothing changed. Complete OLT reboot did not help.


I know that none of the boards are faulty because when I reboot the board2 then board1 comes online and board2 stays with 

RUN/ALM blinking led in red.

Seems like they are working separately and cannot get synchronized. When one board reboots, the other loads up and  becomes 

active, but the recently rebooted board just hangs in the middle of the loading process.


I've connected two console cables, one to each board, and I can see that the board with the red light just stops at the same point 

every time.

The active board on OLT has an alarm which says:


The communication between the board and the control board fails


Here is the console output from both boards:

The board with RUN/ALM red light always stops after


Starting system application init......successfully!


After this line it should start loading config, but it does not until the active board goes for reboot!


I've tried to do a factory reset on both boards (separately) with:


    erase flash data

    reboot system


But it did not work out. Both boards have a default configuration now, but keep doing the same thing again and again. Looks like the 

boards can't sync the configuration between them. Or both want to become Active and only one loads up.


I´ve also upgraded both boards to V100R018C10SPH102. I´ve also erased nand fs by running nandfsformat from the BIOS on both 

boards and then loaded the packetfile. Same situation. There is an option eraseall but i´m not sure that I have the files to restore it.


I tried to google about this situation, but i did not find a single word about it. Seems like some unique situation.

Did anyone have similar problems with Huawei OLT?

Dear customer, 

About your problem - it is probably caused by the following reasons:

when the configuration file is loaded for the first time, only the mainboard of the active and standby boards is loaded, and the backplane is also running. When the system is restarted, if the bootboard is started, the configuration data of the motherboard cannot be up. Therefore, the board 2 can be up, and the board 1 is not activated. In this case, if the two boards are the same version, in principle, the board 2 data can be synchronized to the board 1, and then normal.

You said that board 1 and board 2 can be used normally, so it is better to say that the two boards cannot be backed up each other due to version reasons.

After you erase the data in the board bios, you must find the upgrade software to re-upgrade the version. When upgrading the version, you should have a basic data configuration file. You must install it because it is not clear that you exported it before. Whether the configuration file matches the V100R018C10SPH102 version, so if you want to enable your previous configuration file, you need Huawei's special database upgrade tool to upgrade the configuration file to your current software version. This way you can also load this upgraded configuration file. Otherwise you can only reconfigure the data yourself

Hi, 

Please refer to the below possible causes:

• A serial port, Telnet, or network management system (NMS) user issues a board reset command;
• The service board is not properly connected or is removed;
• The hardware of the service board is faulty;
• The service board fails to communicate with the active control board;
• The service board is powered off because the temperature of it or the control board is high;
• The service board is automatically powered off after the mains supply is cut off;
• The service board is automatically powered off with no service configured;
• A user changes the working mode of the service board so that the board resets;
• The user executes a board prohibit or undo board prohibit command;
• The user runs a command to power off the service board.

Hi. Why did you close this problem? It's very rude from your side. It's not solved. I read this article before and it did not help.

• A serial port, Telnet, or network management system (NMS) user issues a board reset command;
This is not the case, because I had the OLT totally isolated without any single connection but the power without any results
• The service board is not properly connected or is removed;
The service boar IS properly connected. As soon as I reboot the active board, the standby resumes the booting progress.
• The hardware of the service board is faulty;
The hardware is not faulty, because it loads as standalone and it was working before i loaded the config file
• The service board fails to communicate with the active control board;
Yes, i know this, but how can i fix this and make them synchronize? I've tried with other 2 boards and they do work.
• The service board is powered off because the temperature of it or the control board is high;
The temperature is fine, it's not higher than 22 degrees.
• The service board is automatically powered off after the mains supply is cut off;
The board is powered ON.
• The service board is automatically powered off with no service configured;
I've tried the command #board power-on 0/8 and I got a result: Failure: Board does not support the operation
• A user changes the working mode of the service board so that the board resets;
I did not change the working mode, it has only 1 mode which is load sharing.
• The user executes a board prohibit or undo board prohibit command;
I've tried this command but no result
• The user runs a command to power off the service board.
The power off command ends with Failure: Board does not support the operation

What else can I do?

We can't locate the problem through your description. locate and analyze need through configuration information, operation log, lastwords, etc. I suggest you look for TAC processing.

Hi , brother

 

the 2 board transfer data in load sharing mode and the role of 2 board in active-standby , if the active board off (or reboot ), another standby board will become to active . so the service will not be effect .

 

to query the board status you can run below command :

 

huawei>display board 0

 

if you suspect your device any problem , you can query if any alarms generate :

 

huawei>display alarm active all

Hi.

The display board 0 shows:

8       H901MPLA   Standby_failed                       Online


And the alarm result is 

 ALARM 3829 FAULT MAJOR 0x02310000 EQUIPMENT 2019-04-12 11:40+08:00
 ALARM NAME  : The communication between the board and the control board fails

I've checked Huaweis doccumentation and the result always leads to "Contact Huawei support".

The RUN/ALM is blinking (on for 0.25 s and off for 0.25 s repeatedly) whic means that the board is loading, but it never finishes to load. It hangs on 

Starting system application init......successfully!


And after some time the boar reboots and stays at the same line. The only thing that changes is that it is trying to load from a different program and data area.
