Can not create disk of required size

Running esx 5.5 with vshpere 5.5 appliance and VNX5400 san

On one site I have created a 19TB Lun and datastore I have then added a 17TB second disk disk to a win 2012r2 guest with no problem (this guest was created in v5.5)

However when I try to do the same on the second site it will only let me have a 16TB disk, (this guest was created when the host was still v5.1)

I get an 'insufficient disk space' message in the event list.

The OS disk and the VM are located on a different datastore.

Any ideas?

Did you upgrade your VM hardware version and also your datastore VMFS?

I think, it's related to your VM configurations because vSphere 5.1 supports 2TB VMDK and if your VM is still using hardware version 9, it can support VMDK improvement on vSphere 5.5.

Yes, you need to upgrade VM version and VMFS datastore. Plz note that upgraded VMFS datastore will not have full capabilities as compared to newly created VMFS 5. If possible plz go for new VMFS 5.

Hi

Welcome to communities.

I am agree with them first need to convert to VMFS.

but we need to check if any log file have consumed unexpected storage size and run below command too.

Thanks, was already at vmfs5 on the datastore, as soon as I upgraded the guest hardware to VMX-10 I could expand the disk.
