由于服务器IP重复、ESXi主机iSCSI数据存储库路径已关闭
适用场景
- ONTAP 9
- iSCSI
- VMware ESXi
问题描述
- 已登录
vobd.logESXi支持包的存储设备路径冗余已降级：

esxcfg-mpath_-b.txt显示数据存储库的某些路径标记为Dead：

C2C4C6上面的、) 都链接到相同的vmkernel接口和IP地址 - 同一主机上的多个LUN会受到影响
- 在其他主机上、LUN没有路径问题
- 重新扫描或主机重新启动后、这些路径会 在几分钟内处于活动状态、然后会再次失效
- NetApp EMS显示来自相同IP地址但不同IQN的新iSCSI会话：
