Hi Siva,
Thanks for reply..
I enabled it during the first pass and reconfigured the VM. I have verified it on the vSphre client GUI also. Its showing ctkenable &scsi:ctkenable flag as true :
code snippet:
vmConfigSpec.setChangeTrackingEnabled(true);
ManagedObjectReference tmor
= vimPort.reconfigVMTask(
virtualMachine, vmConfigSpec);
with thanks,
Santosh
