看到存储做了raid dp 初步断定硬盘损坏，数据不受影响
由以上日志可看出，坏盘一共四块，坏在两个raid组中，vol status -r 命令查看热备盘已用完，无法进行坏硬盘更换，而下方硬盘没有被控制器二所接管，无法看到硬盘具体状态。
2.更换控制器二所属的硬盘
①将坏掉的硬盘拔出，等待30秒（防止磁盘断电后还在转动，防止磁盘造成物理损坏为数据恢复增加困难），插入新硬盘（确认黄灯亮、绿灯不闪烁）
②插入硬盘后disk show -v 查看新硬盘是否分配了owner（控制器）

使用disk assign -f <disk_id> -s <owner_id> 强制分配给一个控制器 *慎用，分配完成后使用disk show –v查看是否分配成功
使用aggr destroy <aggr名称> 删除一个AGGR *慎用③使用vol status -r 查看硬盘状态，如果硬盘为Bad Label，执行步骤（1）；如果硬盘已经进入spare disks中，并且磁盘最后标注了not zerod执行步骤（2）
（1） 在vol status –r中看到带有bad label标签的盘，但是已经将新的硬盘安装上
先priv set advanced 进入高级模式，使用 disk unfail -s <硬盘id 0b.**.**> 去除Bad标签，再退出高级模式priv set

拉起控制器一
控制器一因硬盘损坏，进行保护硬盘，自己关闭了控制器，防止用户继续访问存储造成硬盘的继续损坏导致数据丢失
使用console线直连存储，会进入LOADER>模式，使用help命令查看可用命令，使用boot_ontap命令强制控制器启动（若无法启动，则控制器可能损坏），拉起控制器后进入控制器更换硬盘即可
总结
存储进行重构、初始化需要一段时间，当存储硬盘重构、初始化完成后raid组自动将降级取消，存储正常运行
