The Upgrade Notes: 
++++++++++++++++++

LCG-2_3_0 --> LCG-2_3_1

We first describe the process for sites that are using YAIM. This is followed by
an instruction for sites that depend still on LCFGng.

1) Reconfigure apt on your nodes
--------------------------------

from :

# more /etc/apt/sources.list.d/lcg.list
rpm http://grid-deployment.web.cern.ch/grid-deployment/gis apt/LCG-2_3_0/en/i386 lcg_sl3

to :

# more /etc/apt/sources.list.d/lcg.list
rpm http://grid-deployment.web.cern.ch/grid-deployment/gis apt/LCG-2_3_1/en/i386 lcg_sl3

2) Run the upgrade
------------------

# apt-get update
# apt-get dist-upgrade

This will also upgrade the CA RPMs to the latest release that is in the repository.

3) Adjust the version numbers
-----------------------------

edit your site-info.def, change the following lines:

from :
LCG_REPOSITORY="rpm http://grid-deployment.web.cern.ch/grid-deployment/gis apt/LCG-2_3_0/en/i386 lcg_rh73"
LCG_REPOSITORY="rpm http://grid-deployment.web.cern.ch/grid-deployment/gis apt/LCG-2_3_0/en/i386 lcg_sl3"

to :
LCG_REPOSITORY="rpm http://grid-deployment.web.cern.ch/grid-deployment/gis apt/LCG-2_3_1/en/i386 lcg_rh73"
LCG_REPOSITORY="rpm http://grid-deployment.web.cern.ch/grid-deployment/gis apt/LCG-2_3_1/en/i386 lcg_sl3"

from :
CE_RUNTIMEENV="LCG-2 LCG-2_1_0  LCG-2_1_1  LCG-2_2_0 LCG-2_3_0 R-GMA"
to :
CE_RUNTIMEENV="LCG-2 LCG-2_1_0  LCG-2_1_1  LCG-2_2_0 LCG-2_3_0 LCG-2_3_1 R-GMA"

from :
SITE_VERSION=LCG-2_3_0
to :
SITE_VERSION=LCG-2_3_1


4) Rerun on the CE the YAIM configuration script
------------------------------------------------

This will change the site version and the runtime environment that is published in the information system:

# /opt/lcg/yaim/scripts/configure_CE_torque Your_site-info.def

5) Restart the WLM services on the RB and correct the access rights to the sandboxes
------------------------------------------------------------------------------------

# chmod 773 /var/edgwl/SandboxDir   /var/edgwl/SandboxDir/*

The restart:

# cd /etc/init.d/
# for i in `ls edg-wl*` ; do /etc/init.d/$i restart ; done



Notes for LCFGng 
================

There are no configuration changes in this release, except the release version strings in the site-cfg.h file.

1) Download new rpm list files as described on the release page
     
     Note that this will include an upgrade to the new list of CA RPMs.

2) Change and extend the version strings in the site-cfg.h 

#define SITE_EDG_VERSION     LCG-2_3_1
#define CE_IP_RUNTIMEENV     LCG-2 LCG-2_1_0 LCG-2_2_0 LCG-2_3_0 LCG-2_3_1 R-GMA

3) create the profiles
   
       ./do_mkxprof.sh  <nodes>

4) On your RBs, follow the step # 5) of the YAIM upgrade procedure.
