VMware vSphere

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?

What version of ESXi and what version of the host client?

Everything is 6.5, using webUI

What version of the host client though?

Not sure what you are asking.  the host client is embedded, so everything is 6.5;  ESX,vCenter

When you login to the host client (https://<FQDN>/ui) if you go to Help -> About in the upper-right, what version does it report?

Here is what I see from the webUI

Help -> About. What version?

Expanding the VMFS dataastore on the installation disk/LUN needs to be done from the command line.

Thank-you Andre, this worked perfectly!!

Dead link. Is this also true if you want to "Increase Storage Capacity" by attaching another LUN?
