Introduction to the Manual Upgrade Procedure

This document is addressed to Site Administrators in charge of LCG middleware installation and configuration.
It is a generic guide to the manual upgrade procedure for any supported LCG node types.
It provides a fast method to upgrade the LCG middleware on the various LCG node types (WN, UI, CE, SE ...) on the top of the following Linux distributions. and refers to the upgrade between the latest LCG versions and the previous one

YAIM



----------------

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_1/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_4_0/sl3/en/i386 lcg_sl3 lcg_sl3.updates

----------------

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 site configuration file

Change your local site-info.def, following the examples provided in /opt/lcg/yaim/examples/site-info.def. A number of new variables have been added for 2.4.0, so you may find it easiest to create a new site-info.def based on the example rather than editing your existing copy. Pay particular attention to the LCG_REPOSITORY variable which must point to the 2.4.0 repository.

The new variables are as follows; 

CA_WGET
CRON_DIR
DCACHE_ADMIN
DCACHE_POOLS
DCACHE_PORT_RANGE
GLOBUS_TCP_PORT_RANGE
GRIDMAP_AUTH
JAVA_LOCATION
JOB_MANAGER
LFC_HOST
MY_DOMAIN
QUEUES
SE_TYPE
VO_<VO_NAME>_QUEUES
VO_SW_DIR

----------------

4) Rerun on the YAIM configuration script 

> /opt/lcg/yaim/scripts/configure_node <site-info.def> <node-type>
