Welcome to the Community,
please provide some more details. Maybe some screenshots will help.

PS: Discussion moved from Japan [ARCHIVED] to ESXi
In the first picture when I select a data storage and then click in "increase capacity".After that the 2nd picture will appear.So I don't see any VMFS which I want to expand.
Do you see the new/expanded LUN size under Storage Adapters?
Please try to do a Rescan to see whether this helps.

the datastore is expanded on the storage side first. Then after a rescan of the HBAs on the ESXi you increase capacity. Have you done it like this?
