状态信息

适用场景

  • 所有 NetApp FAS/AFF 硬件平台
  • 所有 Data ONTAP 版本
  • FC 协议

问题描述

  • 连接的数据存储库上的虚拟机会在单个节点上出现持续断开连接,响应缓慢,冻结和崩溃的情况。
  • 在具有 FC 卷的非虚拟基础架构上也会发生这种情况。
  • 将卷移动到另一个节点可以解决问题。
  • AEN 0x8048 (RECV_ERROR) 在特定 FCP 适配器中、受影响节点的事件日志中经常检测到的消息。

示例:

Thu Mar 05 21:20:10 CET [Cluster1-01: fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:0f AEN 0x8048 (RECV_ERROR) MboxStatus1 0x200 MboxStatus2 0xc0

  • 受影响的 FCP 适配器在"received optical power"同一节点上的剩余容量可能少于其余的容量。请使用以下命令检查此项:

network fcp adapter show -node Cluster1-01 -adapter * -fields sfp-rx-power

  • 未检测到存储系统的内部延迟。
