适用场景

  • AFF C800
  • ONTAP 9

问题描述

  • 已向集群添加新节点、并通过卷移动迁移了数据。
  • 迁移完成后、旧节点将从集群中删除、集群将从有交换机过渡到无交换机。
  • 在此过程中、集群端口e0a和e1a上的缆线从40G铜缆更改为100G铜缆。
  • 执行此交换后、一个节点上的两个集群端口上报告了大量CRC错误和长帧。
  • 报告了nodeIfInErrorsWarnAlert、系统运行状况子系统show报告集群降级。
  • 报告CRC错误的节点多次出现故障:
PANIC: Unknown key type 0 in SK process wafl_exempt18 on release 9.11.1P14 (C)
PANIC: protection fault on VA 0 code 0 cs:rip 0x20:0xffffffff8a950af0 in process NwkThd_00 on release 9.11.1P14 (C)
  • 发生故障的节点上的聚合将进入未知状态(导致中断)、并且WAFL debug vreport show 输出中的VLDB/VLDB之间存在差异。
