HP Proliant 出现严重错误 LED 闪烁 - 该怎么办?

HP Proliant 出现严重错误 LED 闪烁 - 该怎么办?

经过几个小时的纠正工作后,我们的 proliant 服务器停止计算,系统健康指示灯 12 闪烁,根据文档(http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c01706108-8.pdf) 是“检测到严重系统故障(处理器、内存、调节器、热事件、风扇、NMI)” (第 96 页) 的标志。

然后 SSH 就丢失了。我们可以重启并重新获取 ssh(我不在现场),但我不知道该检查什么?有没有日志文件可以找到一些信息?

我找到了这个指南:http://denis.herve.free.fr/trsfrt/HProliant.pdf但对我来说似乎太过强烈了。

我的同事认为可能是 RAM + Swap 过载导致整个服务器崩溃。我不太同意他的观点,因为就我而言,内存问题不会导致严重的系统故障。你对这一点有什么看法吗?

我想知道这是否与我之前的帖子有关系:Linux 服务器在内存完全填满之前进行交换

我们使用的是 ubuntu 14.04。

PS:服务器在地下室,早上可能会有一点水汽凝结......

编辑 根据@Hennes 的评论,我们将服务器移回了客厅。但经过一夜的计算,它又开始闪烁红灯 :-(

现在我正试图弄清楚日志文件。我们今天早上 09:44 左右重启了服务器,以下是最近更改的文件: 在此处输入图片描述

在哪里搜索什么来获取一些错误信息?

我试过 :

-> 这里我不太明白第一列的值是什么,比如 [ 6.731027] :它是自启动以来的秒数吗?

我还在系统日志文件中检查了‘fan’,‘nmi’,‘critical’,没有任何输出。

我记得一些 stackoverflow 问题,人们将整个文件复制/粘贴到外部日志文件网站 - 我不记得名字了 - 如果有人感兴趣,我准备将文件放在网上。

欢迎任何关于在哪里搜索什么关键词的提示。

我们使用带有 docker 和 r-studio 服务器的服务器进行 ML 微积分。我真的怀疑这种使用方式可能是导致此问题的根源,但在 IT 领域我们永远不知道,所以我会明确指出这一点 ;)

感谢您的任何想法。

答案1

假设您的系统是您链接的文档中提到的 ML150 G6,我强烈建议您在系统上设置并使用 Lights Out-100 管理功能。

可以找到基本操作方法这里。一旦您获得了 Lights Out-100 管理的访问权限(我建议您使用 Web 界面,直到您更熟悉 LO100 提供的功能及其使用方式),然后参阅同一文档的第 28-32 页;它展示了如何查看系统的实时传感器和事件信息。通常,如果硬件问题导致重置,它将列在系统事件日志中,在那里找到它会让您了解您的机器发生了什么。无论您是否接触过 LO100,系统事件日志都应该捕获其数据,因此一旦您进入那里,它应该会有一些有趣的事情告诉您。

大部分相同的信息都可以通过你正在运行的操作系统获取,可以通过 /var/log/messages(你已经尝试过但没有成功)或通过 HP 的 Insight 工具获取,这些工具可以安装在一些 Linux 版本上(请参阅http://downloads.linux.hp.com/SDR/project/mcp/是获取这些工具的一个很好的起点)。不幸的是,并非所有事件都会显示在系统日志中,因为它们是特定于硬件的,并且 HP 代理(而不是内核本身)才是对它们进行检测的。

话虽如此,您也可以查看是否已安装并运行 mcelog;它可以捕获一些硬件事件,并且通常在捕获事件时在消息日志中记录一些内容。它通常还会将事件信息记录到单独的日志中,或将其保存在内存中,以便您可以使用 mcelog 命令进行查询。值得mcelog在您的消息日志中查找,或者查看您是否有最近更新的/var/log/mcelog文件。
