关于高磁盘性能利用率的技术说明
简介
本文档介绍当您遇到磁盘性能利用率达到100%时的过程，并且需要检查它是应用程序问题还是硬件问题，您需要运行几个命令来分析情况。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- 思科统一计算系统(UCS)系列
- 惠普(HP)服务器
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。
问题：高磁盘性能利用率
系统工作缓慢且不稳定。您的磁盘性能利用率达到100%。
故障排除
访问管理Web界面并检查存储硬件状态是一种快速而简单的方法。
无法访问思科集成管理控制器(CIMC)时 对HP服务器上的统一计算系统(UCS)系列或集成无人值守(ILO)进行远程管理，您可以使用以下方法获取有关RAID和磁盘的信息：
对于思科统一计算系统(UCS)服务器：
Debian分发使用名为“megacli”的包。
有关此工具的详细信息 — http://hwraid.le-vert.net/wiki/LSIMegaRAIDSAS
如何使用命令 — http://www.mostlychris.com/blog/2009/07/29/check-raid-status-with-megacli/
可下载并安装debian包。
要检查使用哪些硬件控制器，请运行命令sudo lspci -vv | grep -i RAID
例如
82:00.0 RAID总线控制器：LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt]（版本05）
正在使用的内核驱动程序：megaraid_sas
有关此命令的详细信息，请参阅：
以root用户身份运行，运行命令: sudo /usr/bin/megacli

您可以保存日志以供以后分析。
惠普(HP)硬件
对于HP，需要安装Debian的特殊软件包才能访问RAID控制器和物理磁盘。该软件包名为hpacucli_9.40.1-1._amd64.deb
步骤1.安装：
- 使用您的个人帐户登录到您的Linux系统。
- 将软件包下载到您的Linux系统：wget http://downloads.linux.hpe.com/SDR./repo/mcp/debian/pool/non-free/hpacucli_9.40.1-1._amd64.deb
- 运行命令： sudo dpkg -i hpacucli_9.40.1-1._amd64.deb
安装完成后，您可以使用以下CLI工具处理RAID操作：hpacucli
该工具允许从RAID控制器获取适当的信息，并使用RAID组件更改配置。
步骤2.显示控制器配置详细信息，运行命令： hpacucli ctrl all show config detail。

解决方案
有时，其中一个服务器中的电池损坏可能是导致故障的原因。您应该更换它。
这解决了问题并降低了高磁盘性能利用率。
