适用场景

  • E5700/EF570 和 E2800/EF280 具有 25 GB iSCSI HIC 和 E 系列控制器操作系统 11.60.2 或更高版本
  • 主机接口卡( HIC )
  • AutoCode Sync (自动代码同步)( ACS )
  • 替代控制器具有 11.60.1 或更早版本的固件。

问题描述

  • 更换两个控制器后, AutoSupport 在 iSCSI HIC 上触发以下警报

E-Series Notification (Loss of host-side connection redundancy detected) CRITICAL
E-Series Notification (Host multipath driver configuration error detected) CRITICAL

  • Storage Array Profile 显示了所有八个端口只有两个唯一 MAC 地址的控制器使用的 MAC 地址。

示例如下:

Controller in Shelf 99, Bay A
    Host interface:                     iSCSI
     Host Interface Card(HIC):              1
     Channel:                       5
     Port:                        0e
     Link status:                     Connected
     MAC address:                    be:ef:de:ad:be:ef

在更换控制器之前未观察到此行为:

Controller in Shelf 99, Bay A
    Host interface:                     iSCSI
     Host Interface Card(HIC):              1
     Channel:                       5
     Port:                        0e
     Link status:                     Connected
     MAC address:                    00:a0:98:d5:44:c8
