vsphere 4tb and up disk

Running vsphere 5.5 ( i know its not going to be around much longer) i have a vm version 8. trying to add a virtual disk over 4TB and getting an out of range error. I read a KB on vmware (cant find it now) that said over 4 TB should be support. I will get screen shots as soon as back i nthe office but wondering if there are any suggestions out the gate.

It'll be in extended support and technical guidance through September 2020, so no worries. :)

You can't add or expand a VMDK on a running VM past 2TB, power the VM off and add the disk.

The thick client absolutely supports 2TB and larger disks being applied to the VMs.

The limitation affects both Web and Thick client, in that disks can not be expanded past 2 TB or added to the system if larger than 2 TB, without powering the VM off.

If the size of the files allowed on the LUN where you recreating them is instead the limit then you will get the error even when the VM is offline. The cause of this would be a Datastore which is formatted VMFS 3, or which was converted from VMFS 3 and has the old block sizes persisted.

VMDK simply cannot be created larger than 2 TB, than you may have an old VMFS3 volume on your hands or a vmfs v5 volume which was improperly converted from vmfs v3 is possible too.

so feel free to use thick client or web client
