Hi.
That's a BIG question -- let's see if I can keep this simple and straightforward.
TSM is used for it's archive functionality. TSM will accept and hold a file for as long as the configured policy tells it to.
A CMOD Storage Set is connected to a TSM Node, and that TSM Node belongs to a Policy Domain, which largely defines how long a document will be kept, and where.
The 'Where' is defined at the lowest level by a deviceclass, which belongs to a storagepool, which is defined in a copygroup, which belongs to a management class.
The deviceclass will determine which type of device the data is stored on. A 'File' deviceclass will put the data in files on filesystems. An optical or tape deviceclass enables TSM to store data on optical libraries or tape.
You would determine this my logging into TSM's Admin Console (you may have a GUI, but I prefer the command line). On all platforms I'm familiar with, the command is the same: "dsmadmc" (_D_istributed _S_torage _M_anager _ADM_in _C_onsole)
Grab a pen and paper to make notes, but you'll want to run commands like this inside admadmc:
q node
q domain
q policy
q mgmt
... etc ...
You can get more information on any of these queries by adding "format=detailed" or simply "f=d" at the end.
For a list of ALL the things you can query, "help query".
To exit, "quit".
Good luck!
