The administration of your AIX system need to be much better than it
is in order to properly support server applications like TSM.
Consider deploying the public domain 'lsof' command on your system
to see what large files are open in your file systems...

lsof                                    Public domain command to list open
                                        files...  Obtain from vic.cc.purdue.edu
                                        in pub/tools/unix/lsof.
                                        To see network activity, do 'lsof -n'
                                        and look for things like "UDP *:652"
                                        and "TCP *:ftp" (where it will report a
                                        name for services listed in
                                        /etc/services, else a number for
                                        services not listed in that file).
                                        TYPE:
                                         "IPv4" = IP version 4.
                                         "unix" = Unix domain socket.
                                         "VCHR" = Character special file.
                                         "VREG" = regular file
                                         "VDIR" = current directory
