No OCE available for RAID expansion via storcli

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
CLI Version = 007.1704.0000.0000 Jan 16, 2021
Operating system = Windows Server 2016
Controller = 0
Status = Success
Description = None
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

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?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
