PowerEdge:PERC H310、H710、H810控制器日志中的I2C消息

This article applies to   This article does not apply to 

Symptoms

如果您收到随第12代服务器引进的系列8 RAID控制器的TTY调试日志中的I2C消息,这可能不是硬件故障造成的。

 

目前有三条I2C总线:

  1. SEP(底板上的芯片,用于识别设备是否在PHY上并控制LED指示灯模式)
  2. 热传感器
  3. CEM(用于iDRAC的通信嵌入式管理)。

 

如果H310忙于处理数据事务,特别是在JBOD和VD同时访问时,出自CEM的I2C每5秒会中断一次(此处无功能性影响)。由于它被遗漏,因此这导致了那些事件。  

在每次启动期间,iDRAC均必须与RAID控制器通信,以执行清点、状态和其他功能。RAID控制器与iDRAC之间的通信通过名为I2C的总线进行。 

在开发期间,一些消息放置在RAID控制器日志中,以帮助解决问题,但许多消息最终并未被删除。

 

以下是通常看到的内容的示例:

09/04/12 18:55:37: I2C 1 reset!(09/04/12 18:55:37:I2C 1重置!)

09/04/12 18:55:42: I2C 1 reset!(09/04/12 18:55:42:I2C 1重置!)

09/04/12 18:55:42: I2C 1 reset!(09/04/12 18:55:42:I2C 1重置!)

09/04/12 18:55:43: I2C 1 reset!(09/04/12 18:55:43:I2C 1重置!)

09/07/12 20:42:46: One Wire Device detected fd000002aa470533(09/07/12 20:42:46:检测到一个有线设备fd000002aa470533)

09/07/12 20:42:46: EepromInit: Family=33, SN=0547aa020000(09/07/12 20:42:46:EepromInit:系列=33,SN=0547aa020000)

09/07/12 20:42:46: One Wire Device detected fd000002aa470533(09/07/12 20:42:46:检测到一个有线设备fd000002aa470533)

09/07/12 20:42:46: One Wire Device detected fd000002aa470533(09/07/12 20:42:46:检测到一个有线设备fd000002aa470533)

09/07/12 16:00:34: ds1961s_ReadMemoryAuthenticated: EEprom CRC error in Reading AUTHENTICATED data(09/07/12 16:00:34:ds1961s_ReadMemoryAuthenticated:读取已验证的数据时出现EEprom CRC错误)

 

考虑到I2C的特性,这可能会导致数千条有关I2C设备检测和协商的TTY日志条目。

这些消息是无害的,并不表示RAID控制器或iDRAC出现故障。不必因为出现这些消息而更换硬件。

自修订版20.12.1-0002起,这些TTY日志消息就由PERC 8系列控制器较新的固件进行过滤,使得TTY日志中的I2C消息改善(减少)。
