  • 在以上输出中,的最后一个字段 scsi log (示例 b397bbc4c4703801)是 IO Error Numeric Association (ENA) 特定IO事务的。
  • 此 ENA 可用于跟踪 主机端FMA中的IO事务

 

  •  重新尝试写入操作、尝试几次后写入操作会成功、在重新尝试IOS期间、主机会生成IO  错误。
  • Messages 登录以下主机结束报告:

  • 存储端的卷的 状态显示 为 RW
  • EMS 在问题描述期间、中未报告任何错误事件。
  • 受影响的卷 属于Snap镜像目标。
  • 这些SM关系是在看到问题描述之前完全重新同步的。
