在AFF A900和FAS9500平台上处理L2 watchdog重置

适用场景

• AFF A900
• FAS9500

问题描述

• 节点意外重新启动。示例： 

[IPMI.notice]: 036c | 02 | EVT: 6fc124ff | System_Watchdog | Assertion Event, "Hard reset"
[IPMI Event.critical]: L2 watchdog timeout hard reset
 

• 或者、节点在意外关闭后未重新启动。示例： 

[IPMI.notice]: 0076 | 02 | EVT: 6fc302ff | System_Watchdog | Assertion Event, "Power cycle"
[IPMI Event.critical]: L2 watchdog timeout power cycle

• 如果节点重新启动、则EMS日志文件可能会显示以下错误。示例： 

[netapp: splog_main: mgr.boot.reason_abnormal:EMERGENCY]: System rebooted due to a watchdog reset.
[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
