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”。
