节点端口已启动且运行状况良好、但无法访问此端口上的生命周期
适用场景
- ONTAP 9
- 逻辑接口 (LIF)
问题描述
即使端口已启动且运行状况良好、也无法访问端口上的LUN。
从 受影响端口上的SIP执行Ping操作失败：
::> network ping -vserver <vserver_name> -lif <lif_name> -destination XXX.XXX.XXX.XXX
no answer from XXX.XXX.XXX.XXX
从目标主机Ping受影响的生命周期也不成功。
不 允许在ONTAP与目标主机或ICMP端口之间使用防火墙。
配置路由并与网络团队进行验证：
cluster1::> route show
Vserver Destination Gateway Metric
------------------- --------------- --------------- ------
<vserver_name> 0.0.0.0/0 XXX.XXX.XXX.XXX 20
受影响的生命周期的跟踪追踪显示错误- No route to host：
::> traceroute -vserver <vserver_name> -lif <lif_name> -destination XXX.XXX.XXX.XX
traceroute to XXX.XXX.XXX.XX (XXX.XXX.XXX.XXX), 64 hops max, 40 byte packets
traceroute: sendto: No route to host
从受影响端口收集的数据包跟踪仅包含来自ONTAP的ARP：
