ONTAP 9
同步SnapMirror (SM-S)

问题描述

同步SnapMirror不同步、并显示以下上次传输错误。

Last Transfer Error: Failed to configure source. (Failed to re-establish sync usiness Continuity (SMBC) relationship. An Automatic Resync will be triggered soon. Check  snapmirhe state of sync replication)

CG级别也会显示以下其他一些错误消息。

Failed to configure source. (CSM: An operation failed due to an ONC RPC failure.)

Failed to configure source. (SnapMirror operation failed due to one of the following: node reboot, storage failover, storage failback, aggregate relocation, volume move or network connectivity issues. If this is a manual operation, wait a few minutes, and then try the operation again.)

目标集群与源集群之间的集群对等状态为部分/待定。

destination cluster:

cluster_dst::> cluster peer show

Peer Cluster Name Cluster Serial Number Availability Authentication

------------------------- --------------------- -------------- --------------

Cluster_dst 1-80-000011 Partial ok

source cluster:

Cluster_src::> cluster peer show

Peer Cluster Name Cluster Serial Number Availability Authentication

------------------------- --------------------- -------------- --------------

Cluster 1-80-000011 Pending ok

只有源集群的node1才能从目标集群执行集群对等ping操作、而node2源集群则无法执行此操作

dest_cluster::> cluster peer ping -destination-cluster src_cluster

Node: dest_node1 Destination Cluster: src_cluster

Destination Node IP Address Count TTL RTT(ms) Status

---------------- ---------------- ----- ---- ------- -------------------------

src_node1 xx.xx.xx.xx 1 64 0.1 interface_reachable

src_node1 xx.xx.xx.xx 1 64 0.098 interface_reachable

src_node2 xx.xx.xx.xx 1 - - unreachable

Node: dest_node2 Destination Cluster: src_clsuter

Destination Node IP Address Count TTL RTT(ms) Status

---------------- ---------------- ----- ---- ------- -------------------------

src_node1 xx.xx.xx.xx 1 64 0.098 interface_reachable

src_node2 xx.xx.xx.xx 1 - - unreachable

在源集群上、node1上托管的集群间lf会显示当前端口状态、但不会显示node2的端口状态。

src_cluster::> net int show -role intercluster

源集群的node2上的集群间LIF显示已关闭、并且仅node2上的端口也丢失。
