概览

在主机数据收集的 WMI 来源信息中,提供 MPIO 路径故障切换策略的数字值,例如(编辑以实现可读性):

ROOT\WMI 
  DSM_QueryLBPolicy 
    InstanceName = MPIO\Disk&Ven_DGC&Prod_VRAID&Rev_4501\1&7f6ac24&0&36303036303[...] 
    Active = True 
    LoadBalancePolicy = 
      LoadBalancePolicy = 7

可以使用下表解码上述负载平衡策略。有关更多信息,请参阅下面的 参考 部分中的链接。


负载平衡策略定义

故障切换策略和数值关联如下:

Value      Definition 
"1"        "Failover Only" 
"2"        "Round Robin" 
"3"        "Round Robin with Subset" 
"4"        "Dynamic Least Queue Depth" 
"5"        "Weighted Paths" 
"6"        "Least Blocks" 
"7"        "Vendor Specific"
提醒:Dell PowerPath 托管设备被列为具有负载平衡策略“7”、“特定于供应商”。
