如果驱动器连接到 raid 但未配置 raid,如何使驱动器对操作系统可见

所以我有 4 个“未配置的良好”驱动器。它们不在任何虚拟驱动器中。我想展示它们而不将它们更改为JBOD.如何使我的驱动器对操作系统可见,将它们保留为单独的驱动器(不将它们放入任何类型的 RAID)?

答案1

您的 RAID 控制器支持 JBOD(或者可以刷新到支持 JBOD 的固件,这在 LSI 品牌的控制器中很常见),或者您需要解决一个问题:大多数 RAID 控制器允许您执行单磁盘 RAID 0。为了将光盘呈现给操作系统,在本例中,您需要为每个驱动器创建一个磁盘 RAID 0...

答案2

在我的 HBA (LSI MegaRAID SAS 9266-8i) 和固件版本 3.460.115-6465 上,需要启用 JBOD控制器。完成此操作后,所有不属于 RAID 的驱动器都会自动从“未配置良好”更改为 JBOD 状态。

无法设置-

root@olive:/home/hbarta# storcli /c0/e252/s2 set jbod
Controller = 0
Status = Failure
Description = Set Drive JBOD Failed.

Detailed Status :
===============

-------------------------------------------------
Drive       Status  ErrCd ErrMsg                 
-------------------------------------------------
/c0/e252/s2 Failure   255 Operation not allowed. 
-------------------------------------------------


root@olive:/home/hbarta# 

为控制器启用 -

root@olive:/home/hbarta# storcli /c0 set jbod=on
Controller = 0
Status = Success
Description = None


Controller Properties :
=====================

----------------
Ctrl_Prop Value

JBOD      ON    
----------------


root@olive:/home/hbarta#

仍然无法设置,但状态现在是 JBOD -

root@olive:/home/hbarta# storcli /c0/e252/s2 set jbod
Controller = 0
Status = Failure
Description = Set Drive JBOD Failed.

Detailed Status :
===============

root@olive:/home/hbarta# storcli /c0/e252/s2 show
Controller = 0
