  • Submit a GGUS 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 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 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

<p> Dear biomed user,<br/> <br/> You have <font color=“red”>XXX</font> files on SE <font color=“red”>YYY</font> which will be decommissioned by <font color=“red”>X</font>.<br/> <br/> 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.<br/> <br/> The list of the corresponding files is attached/available <font color=“red”>HERE</font><br/> <br/> Also, note that it is <b>not</b> 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. <br/> <br/> Thanks in advance,<br/> The biomed technical team on shift<br/> </p>

Don't forget to customize the <font color=“red”>red text</font>.


<font color=“red”>SE_hostname</font> decommissioning - forbid write access for biomed users


Dear site admin,
The storage element <font color=“red”>SE_hostname</font> 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.
