、在虚拟机上安装的11.2.0.1的RAC，之所以选择11.2.0.1，是因为public IP和Private 网段的问题。 安装实例过程中，电脑死机，重启后，CRS 无法启动。
[root@rac1 bin]# ./crsctlstart crs

除了alertrac2.log 在宕机的时候有更新外，其他文件均无更新。到节点1重启了一下：

1. ocssd is fully up
If ocssd.bin is not fully up, crsd.log will show messages like following:

是OCSSD 进程无法启动。那么为什么OCSS进程无法启动？ 我们对ohasd进程进行strace：
[root@rac1 client]# ps -ef|grep has
root 12192 1 012:44 ? 00:00:00/u01/app/grid/11.2.0/bin/ohasd.bin reboot
root 12281 8085 0 13:05 pts/2 00:00:00 grep has
[root@rac1 client]# strace -p 12192 -o dave.log
Process 12192 attached - interrupt to quit
quit
Process 12192 detached
[root@rac1 client]#
[root@rac1 client]# ls
clscfg.log dave.log gpnptool_11660.trc ocrconfig_13798.log olsnodes.trc
crsctl.log gpnptool_11653.log oclskd.log oifcfg.log
crsctl.trc gpnptool_11653.trc ocrconfig_11312.log oifcfg.trc
css.log gpnptool_11660.log ocrconfig_12191.log olsnodes.log
[root@rac1 client]# cat dave.log
open("/var/tmp/.oracle/npohasd",O_WRONLY <unfinished ...>
这里提示了一条很重要的信息。就是这里的文件，这个文件，我们在安装11.2.0.1的RAC时也会遇到，其应该说是11.2.0.1的一个bug。
参考：
Oracle 11gRAC ohasd failed to start at /u01/app/11.2.0/grid/crs/install/rootcrs.pl line443 解决方法
http://blog.csdn.net/tianlesoftware/article/details/7697366
所以在启动CRS之前，先在2个节点指定dd命令：
[root@rac1 client]# /bin/ddif=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
然后启动，这没有问题了：
[root@rac1 bin]# ./crsctlstart crs
CRS-4123: Oracle High Availability Serviceshas been started.
[root@rac2 bin]# ./crsctlstart crs
CRS-4123: Oracle High Availability Serviceshas been started.
[root@rac2 bin]#./crsctl check crs
CRS-4638: Oracle High AvailabilityServices is online
CRS-4535: Cannot communicate with ClusterReady Services

[root@rac1 bin]# ./crsctlstart cluster -all
CRS-5702: Resource 'ora.crsd' is alreadyrunning on 'rac1'
CRS-5702: Resource 'ora.crsd' is alreadyrunning on 'rac2'
[root@rac1 bin]# ./crsctlcheck crs

CRS-4535: Cannot communicate with ClusterReady Services

--查看进程，都拉起来了。注意11g的进程启动有些慢，多等一会。

现在可以处理我们实例，弄好之后在升级到11.2.0.3.4. 免得每次都遇到这种问题。
