在启动两台虚拟机的RAC环境中，我们一般要进行关闭主机，这个时候一般让两台虚拟机分别休眠，经过几次实践，每次重启起来之后，rac环境中会有各种问题，这个问题也困扰了我好久，最近在休眠之前，我会将RAC数据先关的服务先进行关闭，然后就可以很从容的休眠虚拟机了，操作如下：

[Oracle@rac1 ~]$ srvctl stop database -d prod -o immediate
[oracle@rac1 ~]$ srvctl stop asm -n rac1
[oracle@rac1 ~]$ srvctl stop asm -n rac2
[oracle@rac1 ~]$ srvctl stop nodeapps -n rac1
[oracle@rac1 ~]$ srvctl stop nodeapps -n rac2
[root@rac1 ~]# crs_stat -t
Name Type Target State Host

我们关闭其中的一台虚拟机以后，可以在另外的一个节点（虚拟机）上单独将rac启动，操作如下：
首先禁止节点2的ASM实例重启，，然后再启动节点1，操作如下
[oracle@rac1 dbs]$ srvctl disable asm -n rac2
[oracle@rac1 ~]$ srvctl start nodeapps -n rac1
[oracle@rac1 ~]$ srvctl start asm -n rac1
[oracle@rac1 ~]$ srvctl start instance -d prod -i prod1 -o open
[oracle@rac1 dbs]$ crs_stat -t
