Data Domain:检测到 BMC 故障 |BMC 无响应。

Summary: 底板管理控制器(基于 Dell PowerEdge 的平台上的 BMC,又称为 iDRAC)是嵌入在 Data Domain (DD) 系统主板上的集成控制器。 BMC 管理系统管理软件和平台硬件之间的接口。BMC 有自己的专用固件和 RAM。 DD 系统中的传感器向 BMC 报告温度、冷却风扇速度、电源状态、电压等参数。 BMC 会监视传感器并在任何参数未保持在预设限制范围内时发出警报,指示系统可能出现故障。 ...

Symptoms

如果 BMC(或 iDRAC)变得无响应或报告出现故障,则 Data Domain (DD) 系统会生成关联的警报。
DD 报告以下 EventID 之一:
ENVIRONMENT-00019	LegacyBMCHangCritical: BMC module in the controller is unresponsive 		
ENVIRONMENT-00020	BMCHangCritical: BMC module in the controller is unresponsive		
ENVIRONMENT-00038	The system is being shut down. BMC is unresponsive	
ENVIRONMENT-00039	BMC failure has been detected		
系统可能会继续正常运行,但某些环境变量可能不可用,例如温度和其他传感器读数。
在某些情况下,可能会启动系统关机。



Cause

常见原因:
  • BMC/iDRAC 对堆栈上层的服务变得无响应。
  • Data Domain Operating System (DDOS) 中的服务失去与 BMC 的通信。
  • BMC/iDRAC 已停止响应(硬件或软件故障)。
  • 组件故障。 

Resolution

始终遵循 KB Data Domain:BMC/iDRAC 重置过程
对于基于 Dell PowerEdge 平台的系统(DD3300、6400、9400、DD9900),可能需要重置“释放残余液”。请参阅 KB Data Domain:DD3300/DD6900/DD9400/DD9900 平台弱电释放(BMC 重置)步骤
