NAME

       dpm-register - register external files in DPNS

SYNOPSIS

       dpm-register  --filesize filesize [ --user owner_user ] [ --group owner_group ] [ --mode filemode ] --pfn pfn --server hostname [ --st sta-
       tus ] [ --help ] filename

DESCRIPTION

       dpm-register registers a given filename with the specified permissions into DPNS:

	  - set the filemode (dpns_chmod) to filemode
	  - set the size of the file (dpns_setfsize) to filesize
	  - add the replica entry (dpns_addreplicax) setting
	    * sfn = pfn
	    * status to status ('O' for Online, 'N' for Nearline)
	    * f_type = 'P' (Permanent)
	    * r_type = 'P' (Primary)

EXAMPLE

	    dpm-register --filesize 525424 --server `hostname --fqdn` 
		 --group biomed --pfn dicom:///1/2/3 
		 /dpm/cern.ch/home/biomed/mdm/1/2/3
