Was this stand-alone DDR or was this running in a virtual machine? When CP initializes he's supposed to verify that all paths coded to a particular device are actually cabled to the same device. We do the same thing if you plug in a new chpid. This does not, however, apply to any of the stand-alone utilities. If this was in a virtual machine, please contact the Support Center to discuss.
