适用场景

  • FAS2750
  • ONTAP 9

问题描述

  • 使用串行控制台从基板管理控制器( BMC )访问 ONTAP 无法登录。
  • "sp-latest-console-log" 下面的发现崩溃消息中获取。

示例:

PANIC: thread (swi4: clock) on cpu 9 hung for 4001 milliseconds in process swi4: clock on release 9.5P6 (C) on Mon Jun  8 11:48:57 JST 2020
version: 9.5P6: Wed Jul 10 19:00:56 EDT 2019
compile flags: x86_64.optimize
HA: current time (in sk_msecs) 2761693006 (in sk_cycles) 4163160460561268

  • 无法通过串行连接使用 Clustershell 。

示例:

BMC node-02> sp      exit


Switching console to BMC


BMC Login: admin
Password: 
Login incorrect
BMC Login: 
Login timed out 

  • 无论连接类型如何, BMC Shell 都可以使用。
  • LOADER提示符正常工作 "Waiting for giveback"并正常显示。
  • 正在从"bmc reboot" BMC Shell 尝试,但无法登录 ONTAP 。
