+=====  Procedure for SE decommissioning  =====
+  *  Submit a GGUS [[biomed-shifts:practices#during_ticket_submission|team ticket]] and assign it to VOSupport.
+    *  The expected decommissioning date should clearly appear in the ticket.
+    *  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

+<callout>
+Dear biomed user,
+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 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.
+The list of the corresponding files is attached/available <text type="danger">HERE</text>
+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.
+Thanks in advance,\\
+The biomed technical team on shift.

+</callout>
+<callout title="Body">
+Dear site admin,
+The storage element <text type="danger">SE_hostname</text> is going to be decommissioned. As it supports VO biomed, we will contact biomed users to let them migrate their files.  Meanwhile, can you please forbid lcg-cr writes from now on to make sure no new file will be created.
+Thank you for your support,\\
+The biomed support team on duty.
