使用storcli发出展开raid6数组

Question

我有一个RAID 930-16i4GB的RAID卡。

我最初是从一个vd开始的，这个vd由RAID6中的4个SSDs组成。

-------------------------------------------------------------
DG/VD TYPE  State Access Consist Cache Cac sCC     Size Name
-------------------------------------------------------------
0/0   RAID6 Optl  RW     Yes     NRWBD -   ON  6.984 TB VD_1
-------------------------------------------------------------

我在系统里一共有6个磁盘

---------------------------------------------------------------------------------------------------
EID:Slt DID State DG     Size Intf Med SED PI SeSz Model                                   Sp Type
---------------------------------------------------------------------------------------------------
134:0     1 Onln   0 3.492 TB SATA SSD N   N  512B MTFDDAK3T8TDT-1AW1ZA 02JG547D7A44712LEN U  -

134:2     0 Onln   0 3.492 TB SATA SSD N   N  512B MTFDDAK3T8TDT-1AW1ZA 02JG547D7A44712LEN U  -
134:3     3 Onln   0 3.492 TB SATA SSD N   N  512B MTFDDAK3T8TDT-1AW1ZA 02JG547D7A44712LEN U  -
134:4     4 UGood  - 3.492 TB SATA SSD N   N  512B MTFDDAK3T8TDT-1AW1ZA 02JG547D7A44712LEN U  -
134:5     5 UGood  - 3.492 TB SATA SSD N   N  512B MTFDDAK3T8TDT-1AW1ZA 02JG547D7A44712LEN U  -
---------------------------------------------------------------------------------------------------

因此，我将第五个磁盘(134:4)添加到联机--展开成功工作的RAID数组：

./storcli /c0/v0 start migrate type=raid6 option=add drives=134:4

现在我想添加第6张磁盘。但是，当我试图添加它时，我会得到一个错误：

./storcli /c0/v0 start migrate type=raid6 option=add drives=134:5
CLI Version = 007.1325.0000.0000 June 19, 2020
Operating system = VMkernel 6.7.0
Controller = 0
Status = Failure
Description = None

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

------------------------------------------------------
VD Operation Status ErrCd ErrMsg
------------------------------------------------------
 0 Migrate   Failed   255 Start Migrate not possible.
------------------------------------------------------

知道上一次磁盘扩展时的错误消息为什么没有问题吗？

Answer 1

我和OP有同样的问题，我也很难诊断。执行第一次成功展开后，我尝试使用以下命令添加其他磁盘：

./storcli64 /c0/v0 start migrate type=raid6 option=add drives=0:6-7

答复如下：

------------------------------------------------------
VD Operation Status ErrCd ErrMsg
------------------------------------------------------
 0 Migrate   Failed   255 Start Migrate not possible.
------------------------------------------------------

我找不到一个简单的方法来诊断实际的故障。可能发生的情况的唯一线索是以下命令：

./storcli64 /c0/v0 show all

您也应该得到类似的输出：

VD0 Properties :
==============
Strip Size = 256 KB
Number of Blocks = 125002842112
VD has Emulated PD = Yes
Span Depth = 1
Number of Drives Per Span = 6
Write Cache(initial setting) = WriteBack
Disk Cache Policy = Disk's Default
Encryption = None
Data Protection = Disabled
Active Operations = Background Initialization (89%)
Exposed to OS = Yes
OS Drive Name = /dev/sda
Creation Date = 13-07-2021
Creation Time = 05:45:51 AM
Emulation type = default
Cachebypass size = Cachebypass-64k
Cachebypass Mode = Cachebypass Intelligent
Is LD Ready for OS Requests = Yes
SCSI NAA Id = 600304802411a602287fe50f14e63699
Unmap Enabled = N/A

就我而言，你可以看到：

Active Operations = Background Initialization (89%)

要获得更多有关这方面的详细信息，请执行：

./storcli64 /c0/v0 show bgi

这将提供与迁移类似的输出，包括：

-------------------------------------------------------
VD Operation Progress% Status      Estimated Time Left
-------------------------------------------------------
 0 BGI              89 In progress 17 Hours 53 Minutes
-------------------------------------------------------

似乎一旦迁移完成，这并不意味着控制器已经准备好了，它必须运行一个后台初始化步骤。

Answer 2

好的。我不知道在过去的一个多小时里，我的职位发生了什么变化，但是我再次执行了这个命令(从我原来的岗位上发出的同样的命令)

./storcli /c0/v0 start migrate type=raid6 option=add drives=134:5

而且它还在工作--显示出在扩张完成前还剩24小时。
