我有一個 RAID 930-16i 4GB RAID 卡。
我最初使用由 RAID6 中的 4 個 SSD 組成的單一 vd

DG/VD TYPE State Access Consist Cache Cac sCC Size Name

我的系統共有 6 個磁碟

於是我就去添加第5塊盤（134:4）來在線擴容RAID陣列，成功了：
./storcli /c0/v0 start migrate type=raid6 option=add drives=134:4
我現在想新增第 6 個磁碟。但是，當我嘗試添加它時，出現錯誤：
./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.
------------------------------------------------------
之前的磁碟擴充正常時為什麼會出現錯誤訊息，有什麼想法嗎？
答案1
我和OP有同樣的問題，我也很難診斷。在執行第一次成功擴展後，我嘗試使用以下命令添加其他磁碟：
./storcli64 /c0/v0 start migrate type=raid6 option=add drives=0:6-7
哪個回應：
------------------------------------------------------
VD Operation Status ErrCd ErrMsg
------------------------------------------------------
0 Migrate Failed 255 Start Migrate not possible.
------------------------------------------------------
我找不到一種簡單的方法來診斷實際故障。關於可能發生的情況的唯一線索是以下命令：
./storcli64 /c0/v0 show all
您也應該得到類似的輸出：
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，您可以看到：
Active Operations = Background Initialization (89%)
要獲取更多詳細信息，請執行：
./storcli64 /c0/v0 show bgi
這應該會為遷移提供類似的輸出：
-------------------------------------------------------
VD Operation Progress% Status Estimated Time Left
-------------------------------------------------------
0 BGI 89 In progress 17 Hours 53 Minutes
-------------------------------------------------------
看來，一旦遷移完成，這並不意味著控制器已準備就緒，它必須運行後台初始化步驟。

好的。我不知道自從我發布以來過去 1 小時左右發生了什麼變化，但我再次執行了該命令（與我原來的帖子相同的命令）
./storcli /c0/v0 start migrate type=raid6 option=add drives=134:5
並且它正在運行 - 顯示距離擴展完成還有約 24 小時。
