CAUSE: Installer has detected that the diskgroup name provided already exists on the system.
ACTION: Specify different disk group.
这里提示原来的磁盘组已经存在
解决办法,将所有的磁盘清掉,不能只清理一个
dd if=/dev/zero count=10 bs=512 of=/dev/asm-diskb
dd if=/dev/zero count=10 bs=512 of=/dev/asm-diskc
dd if=/dev/zero count=10 bs=512 of=/dev/asm-diskd
以上操作完成后
grid用户的oracle_home和oracle_base目录也一起删除掉了,重新安装需要重新创建.
