Hi,

we have a new Dell PowerEdge R730xd server setup and preconfigured with DellEMC Customized Image ESXi 6.5 Update 1 A08 (based on ESXi VMKernel Release Build 7388607) .

I am using VSphere Essentials License.

Without any changes, I logged into the Vsphere Web Interface /ui/#/host and attempted to create a new VMFS datastore but got an error:

Failed to create VMFS datastore test – Cannot change the host configuration.

SPECS Used:

Name: Test

Devices: 1 x 10TB Virtual Disk (Raid 10 x 4 Physical Disks) setup by Dell.

Size to create VMFS datastore: 1 TB

VMFS Type:  Both VMFS 5 and 6 failed in separate tests.

No other existing datastores or VM’s.

Contacted Dell but awaiting response and as it ESX they may not help.

As we need this server setup ASAP I was wondering if anyone knows of any resolutions or a point in the right direction with this.

I have used ESX different flavors for years and never seen this before.

Any help or suggestions greatly appreciated.

I also have limited command line experience.
