Some additional glite repositories can be found  here.

Sites should install the  lcg-CA.repo if they wish to allow access to the High energy physiscs community. Any nodes providing information to the BDII information system should install  glite-BDII.repo in their yum repositories.

Glite node type installation is  fully documented here.

Get the dCache software and installing the node.
