+ | ===== 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 | ||
+ | |||

+ | <text background="danger">(red items must to be customized)</text> | ||
+ | |||
+ | <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 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,\\ | ||
