NetApp F3020存储域用户访问异常修复全过程

Mike

　　报警信息：
　　今日同事反应，域账号访问CIFS共享报错，经查看日志报错信息如下所示：

　　Cifs domaininfo查看，显示各PDC连接状态均为Broken(坏掉)且没有连接到任何DC：
　　原因分析：
　　系前一天域控制器升级至Windows2008模式造成；
　　解决方法：
　　显然需要升级存储的操作系统版本才能够支持，怎么样升级了？是否有可升级版本？经查询是可以升级的，只是不知道是否支持Windows2008域模式；

　　FAS3020目前我们使用的版本为7.0.1R即最低版本，它直接的最高版本系统为7.3.7P3：

为了确认7.3.7P3是否支持Windows2008模式，我查看了关于Netapp的官方文档说明：

　　打开NetAPP WEB管理平台，可以看到对应的链接地址：

　　http://mysupport.netapp.com/documentation/productsatoz/index.html

　　http://mysupport.netapp.com/documentation/productlibrary/index.html?productID=30094

　　因为域服务器的配置与文件权限、共享访问有关系，所以域控制器对应的文件如下图所示：

　　【之所以写得这么细，是希望给读者一个思路】支持Windows2008域控制器OK！

　　开始升级：
　　FAS3020 支持的更新文件类型，通过不同版本操作系统更新文件类型不同，Windows的更新文件为.exe，UNIX为.tar，也可以通过网络进行引导修复.e：

　　系统更新可以通过cifs或http等方式进行，我这里设置一个简单的HTTP服务器，确保用户端可以正常访问HTTP目录中的文件：

F3020> software install http://192.168.1.52/737P3_setup_i.exe
software: copying to /etc/software/737P3_setup_i.exe

　　    由于我们没有NETAPP的官方账号，让朋友帮忙下载了一个，结果是：737P3_setup_i.exe，而我们存储支持的是737P3_setup_e.exe,故在进行更新boot引导的时候出现错误警告checksum失败，因无法从NETAPP官网下载对应的系统版本，故从IBM官网下载了最新版本软件（google是万能的）；

　　更新操作：

　　更新系统版本成功，重新下载boot引导也OK；

　　查看域服务器连接正常：

F3020> cifs domaininfo

　　重新CIFS共享服务协议，访问共享正常，查看对应日志信息，通过域账号可以正常访问！

　　至此FAS3020修复完成！
