SATA 热插拔不起作用

Question

你能帮我理解，为什么我的 SATA 热插拔不起作用？当我插入 sata 磁盘时，lsblk不会改变。只有我的系统盘/dev/sda。

我有Linux：

$ uname -a

Linux Z170-D3H 4.9.0-3-amd64 #1 SMP Debian 4.9.25-1 (2017-05-02) x86_64 GNU/Linux

内核设置：

$ cat /boot/config-4.9.0-3-amd64 | 热插拔

SATA控制器：

$ lspci | grep SATA

Answer 1

问题出在错误的 BIOS 配置中。

解决方案（对于我的主板 Z170-D3H）是转到BIOS > Peripherals > SATA Configuration并在此处为每个 SATA 端口启用热插拔选项。然后保存设置并重新启动计算机。

现在一切正常！
