Chapter 20.  Stage Protection

Irina Kozlova

A dCache system administrator may specify a list of DNs/FQANs which are allowed to trigger tape restores for files not being available on disk. Users, requesting tape-only files, and not being on that white list, will receive a permission error and no tape operation is launched. Stage protection can be enhanced to allow authorization specific to a dCache storage group. The additional configuration parameter is optional allowing the stage protection to be backwards compatible when stage authorization is not specific to a storage group.
