适用场景

  • ONTAP
  • 规范Ubuntu Server 20.04

问题描述

  1. 在经验证 的IMT 配置中、VM与映射磁盘的连接丢失
  2. 无法使用在虚拟机管理程序之间实时迁移虚拟机 mpathx: map in use error message
  3. ONTAP 事件日志(EMS)显示了在短时间内创建的许多新iSCSI会话。许多会话来自相同的IQN (主机名)、但多个IP地址(换言之、其他主机使用相同的IQN)。
  4. multipathd未对ONTAP LUN hwhandler='0'使用ALUA
示例消息日志：
CDB: test unit ready
