文章详细记录了在配置 Oracle ASM 实例时遇到的问题，包括 CR、Database、Listener 的安装与 Listener 的配置。重点解决了无法识别 ASM 卷 DATA1 和 DATA2 的情况，通过设置 LD_LIBRARY_PATH 解决了动态库加载问题，并成功识别并挂载磁盘。同时，文章还探讨了在磁盘 ASM 磁盘挂载过程中，一个节点无法正常 MOUNT 的现象，通过查看 ASM 日志找到了问题所在，并最终成功解决。

安装好CRS,Database,配置好Listener后,创建ASM实例,发现无法识别oracleasm创建的ASM卷DATA1,DATA2.

设置LD_LIBRARY_PATH=$ORACLE_HOME/lib后重启服务器生效,DATA1和DATA2可以识别!

当挂在磁盘ASM磁盘时,一个节点无法正常MOUNT.

发现root没有执行/etc/init.d/oracleasm configure进行初始化.初始化后重启ASM,发现已经全部挂载!
