-''lcg-cr'' and ''lcg-del'' should work on every SE of the VO. The ARGO box will help you identify faulty servers. You may use the following straight links: [[https://argo-mon-biomed.cro-ngi.hr/nagios/cgi-bin/status.cgi?servicegroup=SERVICE_SRM&style=overview|SRM service group status]], or [[https://argo-mon-biomed.cro-ngi.hr/nagios/cgi-bin/status.cgi?servicegroup=SERVICE_SRM&style=detail&servicestatustypes=16&sorttype=2&sortoption=6|Critical issues for service group SRM]]
+SRM probes used by ARGO box
+  - https://github.com/EGI-Foundation/nagios-plugins-srm
+  - based on the gfal2 library for the storage operations (gfal-copy, etc)
+  - queries the BDII service in order to build the Storage URL to test given the host-name and the VO name
+  - a X509 valid proxy certificate is needed to execute the probe (configured via X509_USER_PROXY variable).
 __Reminder__: do **NOT** submit a ticket if the service is in **downtime** or it is **not in proper production status**: see on [[http://operations-portal.in2p3.fr/vapor/resources/GL2ResVO?VOfilter=biomed|VAPOR]] the supporting resources or faulty resources.

-The [[https://github.com/frmichel/vo-support-tools/blob/master/SE/lcg-cr.sh|lcg-cr.sh]] script automates the lcg-cr and lcg-del commands on a SE.
+Manual SRM testing (copy file to SE)
+From the biomed-ui.fedcloud.fr VM, where gfal2 is already installed :
+. Build the Storage URL following the model <code>srm://marsedpm.in2p3.fr:8446/dpm/in2p3.fr/home/biomed</code>
+NOTE 1: the model works for DPM SEs, not sure about storm or dCache (a storm example is srm:////storm-01.roma3.infn.it:8444/srm/managerv2?SFN=/biomed)
+NOTE 2: would be interesing to use the probe for building this URL
+. Use gfal-ls to check that we can list the folder
+<code>gfal-ls srm://marsedpm.in2p3.fr:8446/dpm/in2p3.fr/home/biomed/user/s/scamarasu </code>
+. Use gfal-copy to copy a file (in this case, job.jdl) to the above URL
+<code>gfal-copy job.jdl srm://marsedpm.in2p3.fr:8446/dpm/in2p3.fr/home/biomed/user/s/scamarasu/
+  Copying file:///home/spop/dirac/job.jdl   [DONE]  after 17s </code>

+<code>gfal-ls srm://marsedpm.in2p3.fr:8446/dpm/in2p3.fr/home/biomed/user/s/scamarasu
+  job.jdl </code>
+Note that in some cases, the gfal-ls may work (as well as gfal-mkdir), but not the gfal-copy:
+<code>gfal-mkdir srm://clrlcgse01.in2p3.fr:8446/dpm/in2p3.fr/home/biomed/scamarasu

-replace the "ce_name" with the hostname of the CE to check, and submit the job:
-<code>glite-wms-job-submit -a test_ce.jdl</code>
-. Alternatively, download this {{:biomed-shifts:test.jdl|test JDL}}, rename it as test_ce_noreq.jdl and submit it to the concerned CE. Check the BDII (lcg-infosites) to get the full name of a queue on that CE and run the command:
+. Manual HTCndorCE submission
-<code>glite-wms-job-submit -a -r <CE hostname>><port>/<queue_name> test_ce_noreq.jdl</code>
-Then check that the status and the output when the submit command has completed:
-<code>glite-wms-job-status <jobId>
-glite-wms-job-output --dir <local directory> <jobId></code>
-Reminder: __before submitting a ticket make sure one is not open yet__.

   *  **"No compatible resources"**: this type of alarm is most likely a problem on the WMS that did send a job to an inappropriate CE. A non urgent ticket may be submitted to  require the opinion of the admin.
   *  **Maximum number of jobs already in queue MSG=total number of jobs in queue exceeds the queue limit**: each site decides on its policy as to accept of reject biomed jobs. We cannot submit a ticket when the queue is full, given that we use resources in an opportunistic manner.
