    查询错误信息：

 

[oracle@localhost ~]$ oerr ora 15063  
15063, 00000, "ASM discovered an insufficient number of disks for diskgroup \"%s\""  
// *Cause:  ASM was unable to find a sufficient number of disks belonging to the  
//          diskgroup to continue the operation.  
// *Action: Check that the disks in the diskgroup are present and functioning,   
//          that the owner of the ORACLE binary has read/write permission to   
//          the disks, and that the ASM_DISKSTRING initialization parameter   
//          has been set correctly.  Verify that ASM discovers the appropriate   
//          disks by querying V$ASM_DISK from the ASM instance. 

 

 

 

    处理步骤：

         ① /etc/init.d/init.cssd stop

         ② /etc/init.d/init.cssd start

         ③ sleep 90

         ④ restart ASM instance and shutdown immediate

         ⑤ again restart ASM instance

    现在没抛出错误了，不过：

 

SQL> drop diskgroup data;  
drop diskgroup data  
*  
ERROR at line 1:  
ORA-15039: diskgroup not dropped  
ORA-15001: diskgroup "DATA" does not exist or is not mounted 

 

    由于10g中还没有drop diskgroup force的语法，所以这里我们借助linux的dd和dbca配合来强制删除这个老顽固。

    步骤：

        ㈠ 通过查询可知raw5挂在了data身上：

 

[root@localhost ~]# dd if=/dev/zero of=/dev/raw/raw5 bs=1024 count=5  
5+0 records in  
5+0 records out  
5120 bytes (5.1 kB) copied, 0.011998 seconds, 427 kB/s 

 

        ㈡ 在dbca ---> show all ---> 选中raw5 ---> 点击cancel

 

    其实，我已经有water这个diskgroup，也mount上了，对于data这个diskgroup，可以不必管它。
