版本：R6512P06
问题描述
设备没有配置m-lag，但是相关查看m-lag命令会有回显，导致集团巡检系统认为m-lag异常，实验室验证6628P40的版本如果没有配置m-lag，这些命令回显是M-LAG is not configured。
过程分析
M-lag进程启动状态下，输入m-lag相关命令会有回显。大概率是曾经配置过M-lag相关配置，M-lag进程启动了，后续又取消了M-lag配置。
使用下述命令看看进程是否已启动？

如果已启动，则进probe视图关闭一下进程
[H3C -probe]process shutdown job 17609 #这里的job id填上面display process name命令回显的id

Succeeded.

解决方法
probe视图关闭一下进程
[H3C -probe]process shutdown job 17609 #这里的job id填上面display process name命令回显的id
Manually stopping a process might severely affect device operation. Perform this operation only under the guidance of HIK engineers. Continue? [Y/N]:y

Succeeded.
[H3C -probe]
删除mdb文件关闭进程
以单机设备示例， 关闭进程方法如下：
[H3C]dis dev

1. 未配置drni相关配置时drni进程未启动
[H3C]dis process name drnid
The specified process doesn't exist.
[H3C]
2. 配置drni相关配置时drni进程启动
[H3C]drni standalone enable

3. 删除drni相关配置
[H3C]undo drni standalone enable
[H3C]%Apr 8 05:01:17:513 2021 H3C DRNI/6/DRNI_SYSEVENT_MODE_CHANGE: The device's working mode changed to DR system.
[H3C]
[H3C]
[H3C]
4. 保存当前配置
[H3C]save f
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
[H3C]
[H3C]
[H3C]dis dev
Slot Type State Subslot Soft Ver Patch Ver
1 S5560X-54C-EI Master 0 S5560X-6512P06 None
[H3C]
5.查看配置文件名称
[H3C]dis startup
MainBoard:
Current startup saved-configuration file: NULL
Next main startup saved-configuration file: flash:/startup.cfg
Next backup startup saved-configuration file: NULL
[H3C]
[H3C]
6. 删除对应的mdb文件，注意如果是堆叠环境，需要删除每个堆叠成员的mdb文件
<H3C>delete /unreserved startup.mdb
The file cannot be restored. Delete flash:/startup.mdb? [Y/N]:y
Deleting the file permanently will take a long time. Please wait...
Deleting file flash:/startup.mdb... Done.
<H3C>
<H3C>
<H3C>
<H3C>
<H3C>
7. 不保存配置重启
<H3C>reboot f
A forced reboot might cause the storage medium to be corrupted. Continue? [Y/N]:y
Now rebooting, please wait......%Apr 8 05:02:12:121 2021 H3C DEV/5/SYSTEM_REBOOT: System is rebooting now.
