How to publish the LFC and the DPM in the Information System

We assume here that you are using YAIM.

SOLUTION NUMBER 1

Using YAIM, a site BDII will have /opt/bdii/etc/bdii-update.conf like this:

CE  ldap://your_CE.your_domain:2135/mds-vo-name=local,o=grid
SE  ldap://your_SE.your_domain:2135/mds-vo-name=local,o=grid
etc.

At the same time /opt/bdii/etc/bdii.conf will have this:

[...]
BDII_AUTO_UPDATE=no
[...]

In your site-info.def you would define these entries:

[...]
CE_HOST=my_CE.$MY_DOMAIN
SE_HOST=my_SE.$MY_DOMAIN
LFC_HOST=my_LFC.$MY_DOMAIN
[...]
BDII_REGIONS="CE SE LFC"    # list of the services provided by the site
BDII_CE_URL="ldap://$CE_HOST:2135/mds-vo-name=local,o=grid"
BDII_SE_URL="ldap://$SE_HOST:2135/mds-vo-name=local,o=grid"
BDII_LFC_URL="ldap://$LFC_HOST:2135/mds-vo-name=local,o=grid"
[...]

Then rerun YAIM.

SOLUTION NUMBER 2

On the LFC / DPM

On the LFC and DPM machines, fill in all the values you know about in /opt/lcg/etc/examples/site-info.def.

And run :

/opt/lcg/yaim/scripts/install_node site-info.def <node_type>
/opt/lcg/yaim/scripts/configure_node site-info.def <node_type>

BDII Configuration File

In /opt/lcg/yaim/examples/site-info.def, BDII_HTTP_URL points to the BDII configuration file. For instance :

BDII_HTTP_URL="http://grid-deployment.web.cern.ch/grid-deployment/mysite-bdii.conf"

In this mysite-bdii.conf file, define the LFC and/or the DPM :

##################################################################
#
# Locations of lcg-bdii-update configuration files.
#
##################################################################

http://grid-deployment.web.cern.ch/grid-deployment/mysite-bdii.conf

##################################################################
#
#Ldap URLs for use by bdii
#
##################################################################

DPM ldap://<mysite.mydomain>:2135/mds-vo-name=local,o=grid

LFC ldap://<mysite.mydomain>:2135/mds-vo-name=local,o=grid

Using YAIM, install and configure your BDII :

/opt/lcg/yaim/scripts/install_node site-info.def BDII
/opt/lcg/yaim/scripts/configure_node site-info.def BDII

If you modify the mysite-bdii.conf file, restart the bdii service :

service bdii restart
