PG: Will have a look.
Other concerns:
PG: What is the current position with DPM ?
GC: Cambridge 1-5-10 which was well behing the production release. 1-6-4 came (but broken)
Cambridge having problem passing sam tests. Wanted to upgrade to the last release, during
the upgrade to the 1-6-4 broke things. Required fair amount of work to fix the db. Now
we know what to do to go from 1-5-10 to 1-6-4.
GC: We can start to address to upgrade problem at each sites.
Santanu: They where some table that where missing.
Everyone: Yaim changes important.
CB: updates are very frequent difficult to keep up
Current experiment/VO activities and issues
LHCB: Please publish your install system correctly.
JC: MINOS has been changed to minos.vo.gridpp.ac.uk to avoid future conflicts with Fermilab VO
JC: Quite a lot of people willing to get GridPP running. Please more sites install the
GridPP one.
JC: One particular concern is that lhcb could not run everywhere.
OV: Sam tests for LHCB not frequent enough. Should be automatic.
JC: I'll find out.
CB: LHCB seems to have problem with their install but it seems a problem with them.
Middleware upgrades and move to SL4
JC: Wn is availaible. UI is in the pps.
JC: Which sites are upgrading and when ?
PG: Are we going to have sl3 type jobs which fail ?
PG: Is DPM on SL4 supported ?
GC: Works. Does require a couple of additional sl3 rpms ? There is one being tested now
which does not require those additional packages from sl3.
CB: Don't know if we will do a different ce our a subcluster.
DR: LHCB has asked to have a different CE for SL4.
OV: Tags will appear in both subcluster
CB: Will go for a different CE.
AF: Atlas is only trying now...
AF: For release 13 is should work on SL4.
CB: Will do a big bang upgrade.
JC: What do you plan to do to SL4.

GC: Difficult to understand the versions of YAIM.
AF: 3-1-1 is only on the PPS.
CB: Did anyone document how to enable a dns type vo.
JC: Send a link for the minutes.
Helpdesk workflows
PS: Presentation of the slides.
Presented Stephen McAllister, Support Centre Manager NGS
JC: Agent ?
PS: The person to which a ticket is assigned to.
PS: To close tickets
From email: status=closed
From footprint web interface
PS: Please take more responsibility of tickets.
PS: Email us if you have any question about the slides.
JC: Do we agree that if after 3 days the user did not respond then we close the ticket. Yes
What I referred to was slide 8 of the presentation where it says:
PS: " If a solution to a ticket appears to have been delivered for more than
three working days with no activity on the ticket and the ticket is not
at status=Solved, then the Helpdesk should contact the Agent to ask them
to progress the ticket, or grant the Helpdesk permission to close the
ticket."
PS: So, not a blanket closure on tickets apparently solved for more than 3
days, but a definitive process can be initiated after 3 days which may
lead to the closure of the ticket.
JC: When is it going to implement. We started before Anne left.
JC: Santanu is worried that tickets repeat each other.
PS: The problem with the cic on duty
tickets is that it is automatic. If it is automatic we cannot check that there is no duplicate.
JC: The purpose of the presentation is to let you know about the ticket process.
PS: Where we are now is clearly an improvement.
AF: I think it has improved quite a lot.
Storage accounting
JC: Questions about checking that the values in the portal is correct. (ACtion) please
each site check that the figures are correct.
JC: Sam portal moved to gridview. Will be availaible in three weeks.
JC: Moved to Gocdb3
JC: dCache at Imperial ?
OV: Now fine
GC: recommend to upgrade to the last dCache version.
JC: from the review, would be usefull to train sysadm to nagios.
AF: Would be useful.
JC: Will ask on TB support.
PG: Putting it with hepsysman would be a solution.
JC: It seems there is general support.
AOB ?
- GC: Please check the accounting for the storage.
