适用于

  • ONTAP 9.x
  • 过渡(类型 -TDP ) SnapMirror

问题

当对手动创建或通过 7 模式过渡工具( 7MTT )创建的类型 TDP 快照镜像使用多路径时、 SnapMirror 会忽略 SVM 对等过渡关系中配置的“本地 LIF ”参数。

仅当在 SVM 过渡对等关系的 "local-lifs" 参数中定义了集群间 LIF 、并且仅在配置多路径地址时才会发生此问题。  例如、假设一个单节点目标集群,其中两个集群间 LIF 配置在同一个 IPspace 、 "IC1" 和 "IC2" 中。

ClusterA::> network interface show -role intercluster
            Logical    Status     Network    Current              Current Is
         Vserver    Interface   Admin/Oper Address/Mask         Node          Port    Home
         ----------- ----------  ---------- ------------------    ------------- ------- ----
         ClusterA
                  ic1         up/up     172.16.20.1/24       ClusterA-01   e0a     true
                  ic2         up/up     10.1.1.1/24          ClusterA-01   e0b     true

SVM 对等过渡配置有多路径和定义的 "local-lfs" 参数 "ic2" 。

ClusterA::> vserver peer transition show
Vserver  Source Filer  Multi Path Address Local LIFs
-------  ------------  -----------------  ---------------
svmTDP   7mode_source  192.168.1.200      ic2

但是,当查看位于/etc/log/snapmirror目标控制器节点上的 SnapMirror 类型 -TDP (过渡)日志时,我们会看到 SnapMirror 使用 "IC1" 和 "IC2" 连接到源 7 模式控制器。
