从S7700集群系统中获取诊断信息和日志文件

这篇文档主要介绍如何从S系列集群系统中获取诊断信息和日志文件。当集群系统运行异常时可以将设备诊断信息和日志文件传输到文件服务器上，用于分析定位故障原因。

1. 手动保存最新的日志文件。日志文件会定时进行保存，建议在获取日志文件时，手动将缓存区中的日志信息保存到日志文件。

   <HUAWEI> save logfile all  
   Info: Save logfile successfully.         
   Info: Save diagnostic logfile successfully.

2. 将设备的诊断信息保存到dia-info.txt文件中。

   <HUAWEI> display diagnostic-information dia-info.txt 
   Now saving the diagnostic information to the device
       100% 
   Info: The diagnostic information was saved to the device successfully. 

   • txt文件的缺省保存路径为设备存储器根目录，例如flash:/，用户视图下使用dir命令可以确认文件是否已生成。
   • 该命令主要用于问题定位，搜集系统诊断信息，搜集时可能会影响系统的性能（例如CPU占用率升高等）。因此，在系统正常运行时不建议执行该命令。并且，严禁在连接到设备的多个终端上同时执行该命令，否则可能造成设备的CPU占用率明显增高，导致设备性能下降。
3. 通过FTP方式将诊断信息文件和日志文件传输到文件服务器。这里集群系统作为FTP客户端，文件服务器作为FTP服务器端，文件服务器已开启FTP功能。
   1. 执行dir ？查看当前集群系统的存储器状态。通过下面的显示可以看出该集群系统4块主控板的存储器分别为：1/9#flash、1/10#flash、2/10#flash、2/9#flash。

      <HUAWEI> dir ？    
        1/9#flash:        Device name                        
        1/10#flash:       Device name                        
        2/10#flash:       Device name                        
        2/9#flash:        Device name                        
        /all              List all files                     
        /all-filesystems  List files on all filesystems      
        STRING            [drive][path][file name]           
        flash:            Device name 

      集群系统槽位号是二维的，由框ID和槽位号组成。如上：1/9、1/10、2/10和2/9表示集群系统的主控板槽位号。其中1和2表示框ID，9和10表示主控板所在的槽位号。真实环境中集群系统主控板槽位号可以通过执行命令display device获取。

   2. 集群系统与文件服务器建立FTP连接。192.168.1.6是文件服务器的IP地址。

      <HUAWEI> ftp 192.168.1.6                                           
      Trying 192.168.1.6 ...                                             
      Press CTRL+K to abort                                                
      Connected to 192.168.1.6.                                          
      220 WFTPD 2.0 service (by Texas Imperial Software) ready for new user
      User(192.168.1.6:(none)):test                                         
      331 Give me your password, please                                    
      Enter password:

   3. 将集群系统的诊断信息文件上传到文件服务器。

      [ftp] put flash:/dia-info.txt  
      200 PORT command okay         
      150 "F:\ftp\dia-info.txt" file ready to receive in ASCII mode                    
      226 Transfer finished successfully.                                              
      FTP: 3361771 byte(s) sent in 5.995 second(s) 547.61Kbyte(s)/sec. 

   4. 将4个主控板的用户日志文件和诊断日志文件上传到文件服务器。
      这里是以获取最新的诊断日志文件和用户日志文件为例，如果想要获取已经压缩的日志文件，只需要把文件名修改为压缩后的zip文件即可。

      [ftp] put 1/9#flash:/logfile/log.log log-1-9.log                                     
      200 PORT command okay                 
      150 "F:\ftp\log-1-9.log" file ready to receive in ASCII mode                         
      226 Transfer finished successfully.
