Running a nested esx environment:

Initial (nested) ESX disk was 100G, I increased to 150G on the outer vCenter and looks good.

In the nested vCenter:

still shows 100G

Connect to the ESX directly, from webUI -> increase datastore capacity->expand an existing VMFS datastore extent

(it shows 150G for capacity)

Selected the vmfs partition and the after picture looks perfect.

and when I run it, I get the error:  Failed to expand VMFS Datastore - cannot change host configuration

Any ideas?
