背景:
我们将Oracle 11gR2(11.2.0.4)在RedHat EnterPrise 5.8上通过RDAC完成的多路径链路冗余，在部署完成后，我们需要做多路径链路冗余测试，我们的光钎链路连接方式如下。我们做多路径测试完成了如下几个组合：
拔线测试组合一：
1、 先拔下光钎链路 ②和④ 一切正常没有问题；插上五分钟后执行第2步。
2、 再拔下光钎链路 ①和③ 数据库服务正常，crs进程crash无法访问，手工重启crs进程即可。
拔线测试组合二：
1、 先拔下光钎链路 ①和③ 一切正常没有问题；插上五分钟后执行第2步。
2、 再拔下光钎链路 ②和④ 数据库服务正常，crs进程crash无法访问，手工重启crs进程即可。
拔线测试组合三：
1、 先拔下光钎链路 ①和④ 一切正常没有问题；插上五分钟后执行第2步。
2、 再拔下光钎链路 ②和③ 一切正常没有问题；
拔线测试组合四：
1、 先拔下光钎链路 ②和③ 一切正常没有问题；插上五分钟后执行第2步。
2、 再拔下光钎链路 ①和④ 一切正常没有问题；
控制器切换测试组合：
1、 进入存储管理控制台，查看当前磁盘所在控制器为A控，手动全部切换到B，一切正常没有问题。
2、 五分钟之后，再次进入存储管理控制台，将所有磁盘从B控制器切换到A控制器，一切正常没有问题。
问题现象:
问题发生在第一组和第二组的的测试2上面，问题现象如下:[grid@db01 ~] $ crs_stat -t -v CRS-0184: Cannot communicate with the CRS daemon.

故障处理有两种方法：
多路径切换层面，参考如下:
FailOverQuiescenceTime:
Quiescence Timeout before Failover (Mode Select Page 2C) command. Thetime,in seconds,the array will wait for a quiescence condition to clear for an explicitfailover operation. A typical setting is 20 seconds.
FailedPathCheckingInterval:
This parameter defines how long (in seconds) the MPP drivershould wait before initiating a path-validation action.Default value is 60 seconds.

ASM检测时间方面：
只需要调整ASM隐含参数 _asm_hbeatiowait的值将其调大些，我这直接调到120了，重新执行五组测试，问题没有再现，故障解决。
（参看隐含参数值得方法参考:archive-1980）
