在FAS27XX、AFF A220和AFF C190平台上处理L2 watchdog重置

适用场景

• FAS27XX系统
• AFF A220系统
• AFF C190系统

问题描述

• 节点意外重新启动
• 节点在意外关闭后不会重新启动

受影响节点上的BMC日志显示以下内容： 

Record 402: Thu May 05 06:20:35.070000 2022 [ASUP.notice]: First notification email | (REBOOT (abnormal)) WARNING | Send failed
Record 403: Thu May 05 06:20:40.640000 2022 [IPMI.notice]: 0076 | 02 | EVT: 6fc302ff | System_Watchdog | Assertion Event, "Power cycle"
Record 404: Thu May 05 06:20:40.640000 2022 [IPMI Event.critical]: L2 watchdog timeout power cycle

• 如果节点重新启动、则在EMS日志文件中会显示以下错误

Thu May 05 15:33:43 +0800 [netapp: splog_main: mgr.boot.reason_abnormal:EMERGENCY]: System rebooted due to a watchdog reset.
Thu May 05 15:33:43 +0800 [netapp: splog_main: callhome.reboot.watchdog:alert]: Call home for REBOOT (watchdog reset)

• 如果节点无法重新启动、system senors则BMC可能会在中将显示 Attn_Sensor1 为 Asserted
