我的 1+0 RAID 阵列中的第一个驱动器显示预测故障状态。阵列中有两个驱动器；更换它而不丢失任何数据是否安全？我将用相同制造商/型号的驱动器替换它。据我所知，当只有两个磁盘时，RAID 1+0 阵列可用作 RAID 1，但我以前从未实际处理过。
答案1
是的。
这是标准的热插拔情况。在 HP Smart Array 语言中，RAID 1+0 是具有两个磁盘的 RAID 1。故障预测指示器应位于坏磁盘上。您可以在系统运行时交换磁盘。
答案2
是的，应该是安全的。只需确保更换正确的磁盘即可。
顺便说一句，多了解一点信息也无妨。哪个操作系统，RAID 设置如何（硬件卡？然后是哪个型号）。SAS 或 SATA 驱动器等。现在您得到的只是一个通用答案。

更换硬盘
The most common reason for replacing a hard drive is that it has failed.
If you insert a hot-pluggable drive into a drive bay while the system power
is on, all disk activity in the array pauses for a second or two while the
new drive is spinning up. When the drive has achieved its normal spin rate,
data recovery to the replacement drive begins automatically (as indicated
by the blinking Online/Activity LED on the replacement drive) if the array
is in a fault-tolerant configuration.
If you replace a drive belonging to a fault-tolerant configuration while
the system power is off, a POST message appears when the system is next
powered up. This message prompts you to press the F1 key to start automatic
data recovery. If you do not enable automatic data recovery, the logical
volume remains in a ready-to-recover condition and the same POST message
appears whenever the system is restarted.
因此，只需替换它就足以重建它。
如果您在断电时更换它，则需要在 POST 期间按下一个键。
