MSR G2设备格式化后继续使用之前的license

设备格式化以后，文件系统中所有的文件都没有了，这时升级.ipe文件，只能加载出system.bin和boot.bin两个文件，其它安装包均无法加载。这时，怎么才能继续使用原来安装的license文件呢？方法如下：

1.         设备启来以后，查看：

<H3C>dis license                                                               

flash:/license/210235A0WAA1290000012012102416054637474.ak                      

Feature: -                                              

Product Description: -   //显示为一个‘-’，说明license表项对应文件丢失或者损坏                     

Registered at: 2012-05-09 08:41:12                                             

License Type: Permanent                                                        

Current State: In use  //此处虽然显示有用，事实上只是假象，因为目录中的文件已经不存在了。

2、在PC本地找来原来的license文件，down到设备上，此处文件为210235A0WAA1290000012012102416054637474.ak，将该文件copy到license文件夹内，注意名字与display license中显示的名字保持一致：

<H3C>copy 210235A0WAA1290000012012102416054637474.ak license/

Copy成功之后，再查看display license：

<H3C>dis license                                                               

flash:/license/210235A0WAA1290000012012102416054637474.ak                      

Feature: pkg_license                         //此处已经成功识别加载                                                

Product Description: H3C MSR 26 Data Software License                           

Registered at: 2012-05-09 08:41:12                                             

License Type: Permanent                                                        

Current State: In use

3、手动激活license文件：

<H3C>install activate feature flash:/msr26-cmw710-data-a0004.bin               

Upgrade summary according to following table:                                  

flash:/msr26-cmw710-data-a0004.bin                                             

  Running Version             New Version                                      

  None                        Alpha 0004

.                                                                              

%May 24 01:42:40:593 2012 H3C SCMD/6/JOBINFO: The service LSM is running...    

%May 24 01:42:40:604 2012 H3C SCMD/6/JOBINFO: The service SLSP is starting...  

%May 24 01:42:40:658 2012 H3C SCMD/6/JOBINFO: The service SLSP is running...   

最后执行如下命令，使当前配置在下次重启后依然生效：

<H3C>install commit

如果操作无法进行或者失败，建议重启设备之后再次进行该操作

4、输入quit命令，license文件生效：

<H3C>quit
