最近在搞一个大的备份系统，安装了一台stk 700e ，备份服务器：rs6000 p615  ，采用veritas netbackup 5.1  安装完成以后，找不到机械手。

处理过程：

 （1）      首先确认线路是否连接正常。在aix上安装一个legato软件，可以找到机械手，证明设备stk 没有问题。

 （2）     配置ovpass

    
若要安装 ovpass 驱动程序，请输入下列命令：
/usr/openv/volmgr/bin/driver/install_ovpass

要确保在每次系统启动之后驱动程序设备文件都是可访问的，应将下列命令放入系统启
动脚本中：
/usr/openv/volmgr/bin/driver/mkdev_ovpass

删除 scsi passthru 驱动程序
要删除 ovpass 驱动程序，请输入以下命令：
/usr/openv/volmgr/bin/driver/remove_ovpass

./remove_ovpass
./install_ovpass

(3)  配置完成以后，也找不到，呵呵，没有办法了？

（4） 打电话问veritas 了人。说要打补丁。

        没办法，打补丁，找到光盘：

   
 veritas 补丁的安装方法：
 
 （1） 从补丁光盘中copy 出：nb_51_2_m.rs6000.tar，nb_clt_51_2_m.tar到 一个目录下：
 
   /usr/openv/patch
  
  (2)  然后再tar开这两个文件。
    #tar xvf *rs6000.tar
    #tar xvf *clt*.tar
   
  (3) 运行：
    # ./ vrts_pack.install
   
    there are 2 packs available in /usr/openv/patch:
(* denotes installed pack)

        nb_51_2_m
        nb_clt_51_2_m

 enter pack name (or q) [q]:nb_51_2_m
 
 然后再按提示进行。
 

打完补丁，再找一下，ok了，，，，，，，，，，，，

   呵呵，原来也是这样的，，，，，，
