1、建立一个文件系统，大小和ISO p_w_picpath相同或者大些。                         
#crfs -v jfs2 -g datavg -a size=1G -m /iso                            
                                                                      
2.修改文件系统的属性：                                                
#chfs -a vfs=cdrfs /iso                                              
#chfs -p ro /iso                                                      
                                                                      
3.确定新增加的文件系统的逻辑卷设备名：                                
#lsfs /iso                                                            
(假设为：/dev/lv01)                                                   
4.使用dd命令将iso文件复制到文件系统                                   
# dd  if=/oracle/app/product/aix5300-09-01.iso  of=/dev/aix_iso   bs=10M                                     
                                                                      
5.挂载文件系统：                                                      
#mount -rv cdrfs /dev/lv01 /mnt                                       
                                                                      
6.分析：                                                              
在操作系统中访问设备都是通过访问设备文件来达到目的。                  
所以/dev/cd0  与、/dev/lv01  都是可以达到同样的目的。他们的属性都相同。
                                                                      
7.利用挂载的iso 来安装软件                                            
                                                                      
#smitty easy_install                                                  
*input device /directory  for software [/mnt]
