Instructions
-
如果单个双磁盘（具体取决于阵列类型）磁盘处于外部配置，RAID 阵列状态将降级。
-
如果两个以上的磁盘处于外部配置中（具体取决于阵列类型），则 RAID 阵列状态将为失败
示例：
-
由于一个磁盘处于外部配置状态，RAID 5 状态降级。
-
由于两个以上的磁盘处于外部配置状态，RAID 5 显示故障。
-
由于三个以上的磁盘处于外部配置状态，RAID 6 显示故障。
-
RAID 10 显示降级，因为每个跨区中的单个磁盘进入外部配置。
-
由于单跨接中的两个磁盘进入外部配置，RAID 10 显示故障状态
原因：
PERC 控制器不知道硬盘的配置，或者硬盘的当前配置不一致。
故障处理步骤：
如果多个磁盘具有外部配置，并且阵列（如在 RAID 5 中）无法正常工作，则阵列处于故障状态。请尝试执行以下步骤：
- 检查控制器或 Lifecycle Controller （LCC） 日志以查看哪个磁盘上次进入外部状态，但要检查日志中的时间戳。
- 卸下进入外部配置的第一批磁盘，并保留最后一个进入外部配置的磁盘，因为该磁盘上有最新数据。
- 导入磁盘。
- 如果磁盘导入
- 阵列进入降级状态。
- 安装已移除的第一个磁盘并将其导入。
- 如果磁盘导入失败，则清除外部配置并将其设置为热备份，以允许它重建到 RAID 阵列中。
提醒：如果使用相同硬盘的多个阵列包含外部配置，则应基于所有阵列采取作。如果一个阵列正常工作，而另一个阵列无法正常工作，则应导入外部配置。
