2 节点 Stretch MCC

问题描述

MGWD 手动重新启动后，集群对等体变得不可用，PSK 密码丢失。
尝试创建集群对等体失败，并显示以下错误消息：
Error: command failed: Using peer-address XX.XXX.XX.X: An introductory RPC to the peer address "XX.XX.XX.XX" failed to connect: RPC: Remote system error [from mgwd on node "XXXXXXXXX" (VSID: -1) to xcintro at XX.XX.XX.XX]. Verify that the peer address is correct and try again.
升级到本知识库的"适用于"部分中提到的某个版本后，现有集群对等关系也可能会出现这些错误。
在双节点 MetroCluster 系统中，ONTAP 升级后的切回失败，出现以下错误：
Cluster_A1::*> metrocluster switchback -simulate

Error: command failed: Failed to retrieve system image status information for all nodes. Reason: Failed to contact peer cluster "Cluster_B1" at addresses: 10.XX.XX.3, 10.XX.XX.4. RPC: Remote system error [from mgwd on node "Node_A1" (VSID: -1) to mgwd at 10.XX.XX.3, 10.XX.XX.4]. Verify that the nodes are healthy using the "cluster show" command and that cluster peering is available using the "cluster peer show" command, then retry the operation.
InterclusterBrokenConnectionAlert 可能会在运行状况监控中报告。
cluster peer show output 将远程集群的可用性报告为 Unavailable.
cluster peer health show 为空：
::> cluster peer health show This table is currently empty
端口 11104 无响应：
::*> system node systemshell -node Node_A1 nc -zv 10.XX.XX.3 11104 nc: connect to 10.XX.XX.3 port 11104 (tcp) failed: Connection refused
