关于FAILGROUP_TYPE的解释，在如下链接中：
http://docs.oracle.com/cd/B19306_01/server.102/b14237/dynviews_1019.htm#REFRN30170

值得注意的是：
http://docs.oracle.com/cloud/latest/db112/REFRN/dynviews_1024.htm#REFRN30170
http://docs.oracle.com/cd/B19306_01/server.102/b14237/dynviews_1019.htm#REFRN30170
这两个都是讲的V$ASM_DISK，居然内容不一样，通过搜索“FAILGROUP_TYPE”就能看出来。

看来http://docs.oracle.com/cd/B19306_01/server.102/b14237/dynviews_1019.htm#REFRN30170 这个是不更新了。
