I have an issue with RAID expansion for the controller LSI MegaRAID SAS 9260-4i. It looks similar to the case described here but in my case OCE option is unavailable. I've changed 2x10TB HDD to 2x20TB consequently with intermediate synching. But now I can not expand VD1 size to 20TB.

And for the expansion options:
c:\storcli64.exe /c0/vall show expansion

EXPANSION INFORMATION :

--------------------------------------------
OCE - Online Capacity Expansion | WithArrExp - With Array Expansion
VD=Virtual Drive | NoArrExp - Without Array Expansion
You can see no OCE available and empty "WithArrExp" field. If I try to expand VD1 with any options I receive
c:\storcli64.exe /c0/v1 expand size=10240
Status = Failure
Description = expansion operation failed

Previous expansion of VD0 from 2x1TB SSD to 2x2TB SSD worked like a charm without any issues. There is still some space available, probably leftover after size rounding. Can someone suggest what is wrong with VD1?
