All, You can download files from ftp://ftp.software.ibm.com/storage/tivoli-storage-management/tools (for unix (AIX, HP, Linux and Sun) and Windows) to enable the good-old WEBadmin in TSM 5.3 (see the README on the FTP site for details). They state that it will work for at least 6 months or upt March 2006.
Tears were running from my eyes ;-) when I saw the WEBadmin again working on a 5.3 server.......... Cheers, Richard.
