How do I display a list of Tivoli archives?

[Davis Adrian]

We are implementing Tivoli to backup our Unix machines. I want (from a
client) to be able to display a list of archives (The descriptions) which
the client has created using the command line (Not GUI). The only
commands/options I can find related to this display a list of files which
have been archived, whereas all I want is a list of the archive
descriptions. Can anybody help?
Many Thanks,
