适用于

NetApp E 系列

说明

  • Recovery GURU 和主要事件日志 (MEL) 报告以下错误:
    • Loss of host-side connection redundancy detected
    • Volume not on preferred path due to AVT/RDAC failover
  • Host Redundancy Lost 表示主机只有一个控制器的路径。出现这种情况可能有两个主要原因:
    1. 主机仅设置为连接到一个控制器。
    2. 主机在结构中丢失了一条路径,导致通往一个控制器的路径出现故障。这可能是以下任何一种情况的结果。
      • 环境变化,例如布线变化。
      • SAN 错误导致路径失败。
