 =====  Procedure for SE decommissioning  ===== =====  Procedure for SE decommissioning  =====
  
-  *  Submit a GGUS [[biomed-shifts:practices#during_ticket_submission|team ticket]] and assign it to VOSupport. +  *  SE decommissioning should be announced by site admins through a ticket assigned to Biomed VO support. It should clearly state the expected decommissioning date. 
-    *  The expected decommissioning date should clearly appear in the ticket. +  *  Actions on VO admins: send a mail to biomed-users@googlegroups.com
-    *  Notify the concerned site of this ticket (field "Notify site"): this field only appears on existing team tickets, not on the team ticket creation form. So you have to first submit the ticket, then modify the "Notify Site" field. +
-  *  Ask the site admin to forbid lcg-cr writes from now on, using the email template below. To find the email address of the site administrator, do as follow: +
-    *  On the [[https://goc.egi.eu/portal/index.php|GOCDB]], search for the SE hostname (search box). +
-    *  In the results table, click the View link in the Action column; +
-    *  Then click on the site name (Parent Site information)). +
-    *  The admin email is provided in the contact table. +
-  *  **while (decomisioning deadline is not passed)** +
-    *  Get the list of LFNs and DNs having SURLs stored on this SE using [[Biomed-Shifts:LFCBrowseSE | LFCBrowseSE]]: ''LFCBrowseSE se-hostname.domain --vo biomed --lfn --dn --size --summary'' +
-    *  Put a link or attach this list in the ticket +
-    *  Notify the concerned users by email, and attach the list of files. +
-    *  **If** a user does not answer **or** doesn't need his/her files anymore **then** remove all the corresponding entries from the LFC (using lcg-ra <guid> <lfn>) +
-  *  **end while** +
-  *  Once the decommissioning date is passed and the decommissioning is confirmed by the site: +
-    *  make sure that the SE is no longer published in the BDII as supporting biomed, +
-    *  contact the Biomed SAM team (BIOMED-SAMBOX-L [at] in2p3 [dot] fr) that maintains the biomed Nagios box, and ask to remove the SE from the list of resources monitored by Nagios. +
-    *  Send the list of files of biomed users to the LFC administrator to remove the entries from the catalog: dbouvet [at] in2p3 [dot] fr+

-Dear biomed user,+Dear Biomed users,
  
-You have <text type="danger">XXX</text> files on SE <text type="danger">YYY</text> which will be decommissioned by <text type="danger">X</text>.+we've received notice that the SE <text type="danger">SEName</text> (hosted by site <text type="siteName">SSS</text>), which is used by Biomed, will be decommissioned on <text type="danger">date</text>. 
  
-We have to move these files away or remove all the corresponding entries from the LFC (using lcg-ra <guid> <lfn>)  in case you no longer need the data. Please don't hesitate to contact us (biomed-technical-support [AT] googlegroups [DOT] com) in case you have any questions or if you experience difficulties in this process.+This is tracked through the following ticket: 
 +<text type="danger">GGUS link</text>
  
-The list of the corresponding files is attached/available <text type="danger">HERE</text>+If you have files on this SE, please consider checking quickly whether they have replicas somewhere else, or whether you should get/replicate them to avoid any data loss.
  
-Also, note that it is **not** recommended to try to move many files in parallel: due to scalability issues of the SE, only a limited number of concurrent connections can be initiated.+You can find relevant LFNs using 
 +dirac-dms-find-lfns --SE=[SE name] Path=/ 
 +then 
 +dirac-dms-replica-metadata fileContainingLFNs SE 
 +should return available replicas of individual files. 
 + 
 +Kind Regards 
 +<text type="danger">Name</text> for Biomed support
  
-Thanks in advance,\\ 
-The biomed technical team on shift.
