链路不稳定导致集群互连延迟较高
适用场景
- FAS 和 AFF 系统
- ONTAP 9
问题描述
- 集群互连延迟增加
示例：qos statistics volume latency show显示Cluster延迟

- EMS日志中出现多个CSM不匹配错误
示例：
[NODE1: server_common_RPC: csm.mismatchRemoteDevice:error]: CSM connection between source LIF 1001 and destination address 198.168.0.1 might not be optimal for session XXXXXXXXXXXXXXXX. The source is currently connected to InterfaceName(xxxxxxxxxxx) remote device and the destination is currently connected to - remote device.
