Hi Duncan,
The quote from David Smith on this
"the selection between replicas is essentially random. (i.e. a
pseudo-random number is generated and is used to choose one of the
replicas). In fact the list of possible replicas is trimmed down to
those on a disk server with a domain matching that of the client (i.e.
the peer sending the 'get' request to the DPM server or the SRM server).
If the trimmed list is empty the whole list is considered again. "
