问题描述

  • ActiveIQ中报告了MetroCluster 系统的以下风险
An incorrect number of adapters is used for the MetroCluster backend connection.
  • 某些磁盘架中的磁盘没有预期的8个路径。

  • 本地站点的两个节点均缺少远程ATTO网桥。但是、远程站点会发现缺少的网桥。

::> system node run -node node1 -command sysconfig -a

  • 在本地站点的两个节点上、缺少的网桥连接到同一个光纤交换机。
  • 连接到缺失ATTO网桥的交换机端口已联机。
