适用场景

  • iSCSI
  • SAN
  • ONTAP 9

问题描述

  • iSCSI LIF已从LUN所在的高可用性(HA)对中删除  
  • 客户端通过其他HA对上的间接路径访问iSCSI LUN
  • 在ONTAP 接管或节点重新启动期间、iSCSI客户端将丢失iSCSI LUN连接

例如:

有一个4节点集群、一个HA对的节点N1和N2、N3和N4形成另一个HA对

  1. 在节点 N1 上创建 LUN
  2. 为每个节点创建一个 iSCSI LIF 接口
  3. 将所有 4 个节点配置为 SLM eporting-nodes 
  4. 从 N1 和 N2 中删除 LIF
  5. 重新启动节点 N1 或 N2
  6. iSCSI主机将丢失LUN连接、系统将挂起
