Linux检查独服硬盘通电时间

在我们选择的服务器，有些时候需要检测服务商的服务器的通电时间，这样也可以检测这个服务器的质量。

以下是Linux检查独服硬盘通电时间的命令：

smartmontools工具安装：

#Ubuntu / Debian：
apt-get -y install smartmontools

或者

#CentOS：
yum -y install smartmontools

没有做raid的情况：

smartctl -A /dev/sda

做了raid的话可以用以下命令查看：

Disk A
smartctl -a -d cciss,0 /dev/sda
Disk B
smartctl -a -d cciss,1 /dev/sda

一般我们会看到如下的输出：

root@zhujidianping:~# smartctl -A /dev/sda
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.13.11-041311-generic] (local build)

找到Power_On_Hours这行的就是通电时间。
