适用场景

  • AFF A700、 AFF A220、AFF A200、AFF C190
  • FAS9000、 FAS8200、FAS2750、FAS2720、FAS2650、FAS2620
  • ONTAP 9.2及更高版本

问题解答

  • e0M-16是节点上一个隐藏的内部ONTAP接口、用于与其服务处理器(Service Processor、SP)或底板管理控制器(BASEboard Management Controller、BMC)进行通信
  • 它会在192.0.2.x子网中自动配置硬编码的IP地址
  • 在大多数平台上、它用于在SP/BMC和ONTAP内部直接进行SP/BMC固件更新和错误状况报告
HA系统 详细信息
  • AFF A700/FAS9000
  • AFF A300/FAS8200
  • AFF A220/FAS2750/FAS2720
  • AFF A200/FAS2650/FAS620
  • AFF C190
  • e0M-16 (特别是使用VLAN标记16)与e0M共享同一个内部物理以太网端口、但仅限于与其本地SP或BMC进行通信、VLAN标记16也是如此
  • e0M-16始终硬编码为 192.0.2.83。SP或BMC eth0.16 接口始终配置为 192.0.80.8
  • e0M-16位于自己的IP空间(OS2SP)中
  • 在与配对节点的SP或BMC通信时、硬件辅助故障转移不使用e0M-16
  • 在ONTAP 9.2之前的版本中、e0M端口会在这些平台上分叉为e0S
