Well, I'm guessing you are using actual files for tsm volumes...
just define additional space under a file system under aix within the shark
box...
do a
        dsmfmt -m -data /somepath/somefile xxxx  (where xxxx is the size of
the file in MB)
to see the format of dsmfmt just issue "dsmfmt" from a command prompt under
aix.
once that runs and lays down the file, from within an administrative command
line session...(dsmadmc) do
        define volume stgpoolname /somepath/somefile
and boom... done
