主机重启--导致RAC无法启动：
1：存储乱了顺序。
ocr voting /etc/udev/rules.d/60-raw.rules

检查 CSS 日志

2.检查私网是否有问题。
ping
cluvfy

RAC 访问时常中断：
local_listener
ip 情况

有时重启是crs 服务，或者重启 HACMP 就可以解决问题

3.ASM磁盘的权限的不正确（oracle:dba）导致 ASM 进程无法挂起。
原因： /etc/rc.local 中的赋权语句没有生效
解决方法:检查 /etc/rc.local 的赋权语句是否正确
或者手工配置一个 on_os_start.sh 脚本里面添加：
chown oracle:dba /dev/sdb2
....

然后手工在两个节点分别执行：crsctl stop crs; crsctl start crs;
重启集群。
