由于根端口出现PCI错误NMI崩溃、节点关闭
适用场景
- ONTAP 9
- FAS/AFF 系统
问题描述
- 节点关闭并出现类似于以下内容的崩溃：
PANIC: PCI Error NMI from device(s):ErrSrcID(CorrSrc(0),UCorrSrc(0x1a)), RPT(0,3,2): in process idle: cpu7 on release 9.5P6 (C)
PANIC: PCI Error NMI from device(s):ErrSrcID(CorrSrc(0),UCorrSrc(0x8)), RPT(0,1,0): in process idle: cpu9 on release 9.9.1P15 (C)
- 在崩溃字符串之前、可能还会出现以下其他错误：
000000 2021 [SysFW.notice]: Device 10/0/0 (CNA0) failed to train at max link width - retraining
000000 2021 [SysFW.notice]: - Expected x4, actual x1
000000 2021 [SysFW.notice]: Device 10/0/0 (CNA0) failed to retrain at max link width- 可以从
PCI-HIERARCHY.XML日志中确认以下输出：
PCI Device Level:1
