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）
