Richard,
Thanks,
 I had done the query filespaces and checked that they were unicode in both
cases but missed the very small differences in the hexadecimal filespace name.
So If I had renamed the old filespaces using the hexadecimal option, would TSM
then have been happy and not created new FSID's
Is there a query  that would give you the new hex name, before the first backup,
or would you
have to backup a file in each of the new drives to get the new hex names, make a
note of them, then delete the new filespaces and rename the old using the new
hex names.
This seems very convoluted.
Has anyone used the rename filespace hex option with success
thanks,
John

John - Do 'Query FIlespace ... F=D' on the old and new filespaces to see all
       the characteristics.  By any chance does one say Unicode and the other
not?  Is the hexadecimal representation of the two filespace names identical?
The latter brings up the knotty issue of client environments versus server
environments in that clients may use odd characters in names whereas the
server does not employ like code pages: what you see on the server in its
character presentation of filespace names may not reveal the reality of the
more intricate encoding used by the client.  In such cases you need to rely
upon the hexadecimal - an added complexity for server administrators.  The
Admin Ref manual talks about this in the various Filespace commands.
