Oracle RAC Study之--删除VOTE DISK
环境：
操作系统： AIX 5300-09
集群软件： CRS 10.2.0.1
数据库： Oracle 10.2.0.1
构建AIX平台下RAC 依据共享存储的使用方式可以分两种：
1、建立基于并发卷组（VG concurrent）的共享存储
2、建立基于ASM下的RAW的共享存储
如下图所示：
本案例是用于基于VG Concurrent 的共享存储：
在添加了vote disk后，主机重新启动后，出现以下错误，并且CRS service启动失败：
[root@aix211: /]#crsctl query css votedisk

1. 0 0
2. 0 0
3. 0 0

5. 0 0
located 6 votedisk(s).
删除错误的磁盘：
