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?
