Liasing with WLCG to follow-up the upgrade. Opened GGUS tickets asking the following:

  • all the sites with older DPM versions than 1.12 are suggested to upgrade to the latest DPM version , following the guide DPM upgrade (chapter 1 Upgrade to DPM 1.10.0 "Legacy Flavour" and chapter 2 Upgrade to DPM 1.10.0 "Dome Flavour")
    • DOME and the old LCGDM (srm protocol) will coexist
  • Monitoring: sites should enable the monitoring of the HTTP/WebDav and/or GridFTP endpoints
    • register the storage service endpoint as webdav and/or globus-GRIDFTP service type, with production flag disabled, providing respectively the URL field and the Extension Properties information as explained in the HOWTO21
    • check if the tests are ok
    • switch the production flag to "yes"
