适用场景

  • ONTAP 9
  • 集群模式ONTAP 8.X
  • AFF系统
  • FAS 系统

问题描述

  • 系统报告无法从集群中的一个节点查看集群中的所有磁盘。
  • 无法在无法查看所有配对磁盘的节点上执行接管。
  • 还观察到以下情况:
    • 磁盘在节点A上发生故障并被更换
    • 节点B报告无法接管、因为本地节点缺少配对磁盘
    • 检查 节点B (不拥有故障磁盘的节点)上的STORAGE-FAILOVER.XML 部分。它将在"配对节点上的磁盘"字段中列出旧磁盘的UID。
  • EMS日志可确认是否存在错误:

Mon May 04 21:16:13 GMT [node-name: pmcsas_asyncd_4: sas.adapter.debug:info]: params: {'debug_string': 'A different device detected at 11b.42.6 than what was here previously. Old WWN 5:000cca:0221942:a5 New WWN 5:000c50:07676c8:11.', 'adapterName': '11a'}
