我最近更换了家用服务器上 HW RAID 5 阵列上的一个故障驱动器。我正在运行一台定制机器（即：由我认为可能适合的任何部件组装而成）。HW RAID 控制器是 HP P420 卡，运行 5x8TB RAID 5 阵列，带有一个备用驱动器（计划运行 RAID 6，但我需要订阅）
在我的驱动器发生故障后，我更换了它。我现在正在检查阵列，发现它“准备重建”但不是重建。有什么方法可以命令阵列开始重建？或者能给我提供任何诊断信息？
其他一些答案说其他一些驱动器可能有问题。目前卷运行正常，我没有发现任何数据丢失或性能下降（这是我的家用 NAS）
我也尝试过使用 ssaoffline.iso 工具直接启动到 ssa 的 GUI 版本，如果我只是将 .iso 的内容转储到 FAT32 驱动器上（手册说将内容转储到 Windows USB 驱动器上），它就可以工作，但是系统在启动时挂起，因为它无法挂载“cdrom”文件系统。
感谢您的帮助
替换前的情况如下：
