Duplicate ddb.uuid on VMDKs

We previously setup a default template which we use for deployment of our VMs and the last few days we've encountered an issue where we find that the vmdk file of various VMs are getting created with the same "ddb.uuid".

It only started happening the last few days when we tried to mount the VMDKs on other VMs we get an error. I've looked back at some VMs we created previously and found that the  ddb.uuid were unique but the last 5-6 VMs we created all ended up having the same id.

All the MVs have the ddb.uuid value as "60 00 C2 99 75 99 15 2f-ee 55 00 a9 1a 79 8b 94"

1. Disk DescriptorFile

version=1

CID=de0d8178

parentCID=ffffffff

createType="vmfs"

1. Extent description

RW 10485760 VMFS "WindowsXX-flat.vmdk"

1. The Disk Data Base

#DDB

ddb.adapterType = "lsilogic"

ddb.geometry.sectors = "63"

ddb.geometry.heads = "255"

ddb.geometry.cylinders = "652"

ddb.uuid = "60 00 C2 99 75 99 15 2f-ee 55 00 a9 1a 79 8b 94"

ddb.toolsVersion = "7299"

ddb.virtualHWVersion = "4"

and then when we try to mount the disks with other VMs its gives the error attached. Any reason on the cause.

Cheers.
