状态信息

适用场景

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

问题描述

  • 连接数据存储库的虚拟机  在单个节点上持续断开连接、响应缓慢、冻结和崩溃。
  • 这也可能发生在具有FC卷的非虚拟基础架构上。
  • 将卷移动到其他节点可解决此问题。
  • 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 "received optical power" 在同一节点上的数量可能少于其余适配器。使用命令检查此问题:

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。
