昨天RAID 1镜像中的一个磁盘连接到Adaptec 5405已经死亡，并被新的磁盘所取代，但重build磁盘arrays约2小时后，磁盘就离线了。 Hoster工作人员更新了控制器上的固件并强制arrays在线返回。 系统启动正常， arcconf getconfig 1显示如下输出：

arrays又无法重build并离线。
现在让这个系统恢复在线状态的最好方法是什么？
根据智能驱动器可能处于失败状态，尝试再次重build，如果重新分配扇区数增长 – 这肯定是不好的。
ST1000DM003不支持驱动器 – 请参阅兼容性报告 ，根据我的经验，这些驱动器也有一些固件/兼容性问题。
在全球范围内，从兼容性的angular度来看，Adaptec 5系列存在很多问题，在某些情况下，解决方法是在没有底板的情况下直接连接驱动器，有时在驱动器切换到1.5 gbps（驱动器跳线）时停止。
使用兼容性列表中的驱动器，不要忘记升级驱动器固件。
ps你已经在驱动器上启用写caching，但在控制器上禁用。
