AIX has different types of filesystems (JFS, DFS, AFS, etc).  PC's have
different types of filesystems (NFS, FAT).   Mainframes also can have
different types of coexisting filesystems these days.

Most of the mainframe data is "legacy" MVS format data.  It has a catalog
structure that is very unlike UNIX or Wintel directory structures.  TSM does
NOT understand that type of filesystem.  To back it up, you need an MVS
backup product.

Mainframes can also now have UNIX-style filesystems (which are called HFS
filesystems).  They are directory based, and there is a TSM client that
understands them and can back them up.
