[INS-30507] Empty ASM disk group

    最近的Oracle 11g RAC安装碰到了INS-30507错误，也就是在grid安装到创建ASM磁盘组的时候找不到任何候选磁盘，google了N多安装指导也没有找到蛛丝马迹。如果你碰到这个问题，不妨往下瞧。

1、错误信息与解释 
 
 SEVERE: [FATAL] [INS-30507] Empty ASM disk group. 
    CAUSE: No disks were selected from a managed ASM disk group. 
    ACTION: Select appropriate number of disks from a managed ASM disk group. 
  
 Oracle官方给出的这个解释也太揪心了，舍此之外，着实没有给出任何有用的信息 
 
2、安装时的环境 
  操作系统(Oracle linux 5.5 32bit) 
  [root@node1 ~]# cat /etc/issue  
  Enterprise Linux Enterprise Linux Server release 5.5 (Carthage) 
  Kernel \r on an \m 
 
  Oracle版本 
  Oracle 11g RAC R2(32bit) 
   
  宿主机系统 
  Win7 64bit + vmware server 2.0.2 
 
3、asm磁盘信息及权限 
  [grid@node1 ~]$ oracleasm listdisks

  ASM_FRA 
  OCR_VOTE 
   
  [grid@node2 ~]$ oracleasm listdisks

  #两节点都安装了cvuqdisk包  
  [grid@node1 ~]$ CVUQDISK_GRP=oinstall; export CVUQDISK_GRP 
  [grid@node1 ~]$ rpm -qa | grep cvuqdisk 
  cvuqdisk-1.0.7-1 
  [grid@node2 ~]$ CVUQDISK_GRP=oinstall; export CVUQDISK_GRP 
  [grid@node2 ~]$  rpm -qa | grep cvuqdisk

4、CVU校验结果 
  #安装前的校验

4、分析与解决 
  a.从上面的各个检测情况来看，应该来说配置等方法应该是ok的。如果有问题的话，检测应该有部分无法通过 
  b.其次可以排除ams磁盘文件的属主属组以及权限问题 
  c.Google了N多11g rac安装指导，都没有提到要配置磁盘路径的问题，尝试修改磁盘路径为ORCL:没有结果(记得10g时要这样配) 
  d.尝试重新配置asm driver以及使用asmlib重新创建磁盘未果 
  e.最后在安装界面尝试修改路径为/dev/oracleasm/disk/*，终于转阴为晴阿 
  f.路径下/etc/sysconfig/oracleasm文件可以修改相关SCANORDER以及SCANEXCLUDE
