Adaptec RAID控制器-处于失败状态的逻辑设备

Question

我有一个硬件Adaptec ASR8405 RAID控制器，其中我有15个磁盘RAID6阵列。其中一个磁盘坏了，在替换之后，Controller没有拿起它，没有启动重建，而是进入了失败状态(参见下面)：

正如您可以看到的，逻辑设备的Segment2中的磁盘被报告为丢失，但是在检查物理设备(具有就绪状态)时会显示它：

• 问题1:如何使逻辑设备识别磁盘？我试过在LD上重新扫描，清除，验证和初始化磁盘本身，但没有任何帮助.
• 问题2:是否有机会修复这个问题并恢复数据？我有一个备份，但有超过40 be的数据，从备份恢复这将是不好笑的。
• 问题3:如果我将LD状态更改为最优，是否有可能自行修复？
• 问题4:关于如何解决这个问题，还有其他的想法吗？

非常感谢事先给出的提示！

Answer 1

我已经通过以下方法来修复它：

arcconf SETSTATE 1 LOGICALDRIVE 0 OPTIMAL ADVANCED nocheck noprompt

在改变逻辑驱动器的状态后，数组立即开始自动重建。一旦重建完成，使用Fix验证启动(再次自动)。验证完成后，一切又恢复正常(没有数据丢失)。
