Usage

[phedex] /home/phedex3/projects/PhedexTools > python dcache_retransfer.py 

This script automatically detects and triggers the retransfer of
broken files in dCache.  Deletion and transfers are handled by Phedex. 
The detection method is the one documented in pnfs_tester.py.
The PFN to LFN conversion is done by the same class as tfc_tester.py.
Only files in PNFS_PREFIX are considered, and are not deleted.

Usage:

         python dcache_retransfer.py -prefix=PNFS_PREFIX -storage=STORAGE.XML
         -db DBPARAM:SECTION -node NODE_NAME

SECTION and NODE_NAME should be to corresponding nodes; if you use
the SC4 section, then you should have a '*Load' node name, not 
'*Buffer'.
