主主控板故障，这里主要介绍两类故障，一类是主主控板状态异常，另外一类是内存使用率已经达到或者超过90%，都会影响主主控正常工作，可以使用如下方式进行故障检查：

1. 执行命令display device，检查主主控板MPU(Master)硬件状态是否Abnormal。

   <sysname> display device
    xxxx's Device status:
    Slot #    Type       Online    Register      Status
   Primary
    - - - - - - - - - - - - - - - - - - - - -  - - - - - 
    1         SPU        Present   Registered    Normal
   NA
    2         LPU        Present   Registered    Normal
   NA         
    4         MPU        Present   Registered    Normal
         Slave     
    5         MPU        Present   NA            Abnormal
   Master   
    6         CLK        Present   Registered    Normal
   Master     
    8         PWR        Present   Registered    Normal
   NA         
    9         PWR        Present   Registered    Normal
   NA
    10        FAN        Present   Registered    Normal
   NA

2. 执行命令display health，检查主主控板MPU(Master)内存使用率是否超过90%。

    <sysname> display health
     Slot                CPU Usage  Memory Usage(Used/Total)
    ------------------------------------------------------------
     5 MPU(Master)          6%           95%    1575MB/1712MB 
     1 SPU-CPU0             1%           35%   5517MB/15703MB
     1 SPU-CPU1             1%           34%   5471MB/15703MB
     1 SPU-CPU2             1%           27%   4277MB/15703MB
     1 SPU-CPU3             1%           27%   4282MB/15703MB
     1 SPU-CPU6             5%           16%     56MB/338MB  
     2 LPU                 20%           22%    468MB/2098MB 
    ------------------------------------------------------------
    SPU CPU Average Utilization: 1 %

主备主控倒换：

<sysname> system-view [sysname] slave switchover enable [sysname] slave switchover Caution!!! Confirm switch slave to master[Y/N] Y

说明： 

当进行主备主控倒换时，原来处于主用状态的主控板将重启。

主机SPU/LPU单板反复复位：双机组网中，SPU/LPU单板复位或者某个CPU复位会导致HRP优先级降低，从而触发主备倒换，SPU/LPU单板复位完成后又会触发主备抢占，如果单板处于反复复位的状态，主备状态也在不断变化，会导致业务异常。

在故障管理视图下执行命令display alarm all history verbose，检查是否存在单板或者CPU反复复位的情况。
