我有一张 RAID 930-16i 4GB RAID 卡。
我最初使用由 RAID6 中的 4 个 SSD 组成的单个 vd
-------------------------------------------------------------
DG/VD TYPE State Access Consist Cache Cac sCC Size Name
-------------------------------------------------------------
0/0 RAID6 Optl RW Yes NRWBD - ON 6.984 TB VD_1

我的系统中总共有 6 个磁盘

因此我添加了第 5 个磁盘（134:4）来在线扩展 RAID 阵列，并成功完成：
./storcli /c0/v0 start migrate type=raid6 option=add drives=134:4
我现在想添加第 6 个磁盘。但是，当我尝试添加它时，出现错误：
./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.
------------------------------------------------------
知道上次磁盘扩展成功时为什么会出现错误消息吗？
答案1
我遇到了与 OP 相同的问题，也很难诊断。在第一次成功扩展后，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
其回应是：
------------------------------------------------------
VD Operation Status ErrCd ErrMsg
------------------------------------------------------
0 Migrate Failed 255 Start Migrate not possible.
------------------------------------------------------
我找不到简单的方法来诊断实际故障。唯一可能出现问题的线索是以下命令：
./storcli64 /c0/v0 show all
您也应该获得类似的输出：
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
就我的情况来说，你可以看到：
Active Operations = Background Initialization (89%)
要获取更多详细信息，请执行：
./storcli64 /c0/v0 show bgi
这应该会给出与迁移类似的输出：
-------------------------------------------------------
VD Operation Progress% Status Estimated Time Left
-------------------------------------------------------
0 BGI 89 In progress 17 Hours 53 Minutes
-------------------------------------------------------
看来，一旦迁移完成，并不意味着控制器已准备就绪，它必须运行后台初始化步骤。

好的。我不知道自我发帖以来的 1 小时内发生了什么变化，但我再次执行了该命令（与我原始帖子中的命令相同）
./storcli /c0/v0 start migrate type=raid6 option=add drives=134:5
并且它正在运行——显示扩展完成前还剩约 24 小时。
