DELL 服务器RAID联机扩容OCE|RAID级别迁移RLM？

DELL 服务器 RAID 扩容 或迁移提醒：

  提醒：如果您在同一组磁盘上创建了多个虚拟磁盘 （VD），或者您具有 RAID 50 或 RAID 60，则重新配置的选项将不可用。  

  重新配置和容量扩展作为一项作，不会破坏数据。如果 RAID 阵列存在潜在问题，数据可能会丢失，因此在开始任何作之前，请确保有经过测试的备份可用。      

  注意：重新配置虚拟磁盘时一般会对磁盘性能有所影响，直到重新配置操作完成后为止。强烈建议在维护窗口期间完成该过程。       

什么是联机容量扩展 （OCE）？

联机容量扩展是一个允许虚拟磁盘容量扩展到磁盘组或其包含的硬盘上的现有可用空间的过程。它还允许将新硬盘驱动器添加到磁盘组，以扩展虚拟磁盘的容量。该过程允许扩展，而无需重新创建虚拟磁盘。

什么是 RAID 级别迁移 （RLM）？

RAID 级别迁移是更改虚拟磁盘的 RAID 级别而不要求重新创建虚拟磁盘的过程。物理磁盘可以（有时必须）添加以满足新 RAID 级别的要求。
  您可以在本文 的“其他信息 ”部分中找到 RAID 级别迁移选项的表。

步骤：

1. 通过 F2 >设备设置
   
      访问 BIOS图 1：扩展虚拟磁盘 

2. 选择 RAID 控制器

  重建开始后，可以将系统留在 RAID BIOS 中直至完成，或者系统可以重新引导至作系统。

可能支持的RAID级别迁移：

  提醒：  

• 控制器将所有正在进行 RLM/OCE 的虚拟磁盘的写入高速缓存策略更改为直写式，直到 RLM/OCE 完成。

• 跨接式虚拟磁盘（如 RAID 50 和 60）无法重新配置。

  提醒：如果控制器包含的虚拟磁盘数目已达最大值，则不能再对任何虚拟磁盘进行 RAID 级别迁移或容量扩充。
