概觀

在主機資料收集的 WMI 原始資訊中,會提供 MPIO 路徑容錯移轉原則的數位值,例如 (編輯以供可讀性):

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

您可以使用下表解譯上述負載平衡原則。如需詳細資訊,請參閱下方 「參考」 一節中的連結。


負載平衡原則定義

容錯移轉原則與數位值相互關聯,如下所示:

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"
注意:Dell PowerPath 受管裝置列為具有負載平衡原則「7」,「廠商特定」。
