硬件没有明显错误：
根据资料，只需要执行：
arcconf task start 1 device 0 2 initialize
表示初始化设备，命令执行后，会进行重建raid，使用以下命令查看重建的进度：
[root@admin ~]# arcconf getstatus 1 Controllers found: 1 Logical device Task: Logical device : 0 Task ID : 103 Current operation : Rebuild Status : In Progress Priority : High Percentage complete : 97
完成后，查看状态：

注意：发现raid设备显示Degraded状态时，先检查硬件是否出错，如果没有显示错误信息则表示无需更换硬盘。
