This
\n week SAGrid Core Services added an additional computing element (CE) to
\n their site. This may sound like a complicated task but can be achieved
\n in a few easy steps. The reason you would want this setup is to
\nfacilitate for different clusters. There are a number of other node
\ntypes which could publish to facilitate failure, for example LFC, AMGA,
\nSE, etc …<\/p>\n

1.<\/strong> Configure your new computing element (CE) exactly as you normal
\nwould configure a computing element. A few variables would need to be
\nupdated in your site-info.def file.
NB: Make a copy of the your primary computing element site-info.def file and update the required changes below.<\/p>\n

SITE_NAME = <Site_Name_New_Name>
CE_HOST = <FQDN>
BDII_REGIONS=”PROD_CERN_CREAM_CE”
BDII_PROD_CERN_CREAM_CE_URL=”ldap:\/\/$CE_HOST:2170\/mds-vo-name=resource,o=grid”
<\/span>
2.<\/strong> Reconfigure your Site BDII (site-info.def) to include the new computing element as part of the GRIS. <\/p>\n

The BDII regions are not fixed values which you need to adhere to
\nwithin the grid middleware. The GRIS will identify the service upon a
\nsuccessful yaim. Therefore these values can be used as a description for
\n yourself to identify services at your site. <\/p>\n

Add the following to your site-info.def file. <\/p>\n

BDII_REGIONS=”PROD_CERN_CREAM_CE”
BDII_PROD_CERN_CREAM_CE_URL=”ldap:\/\/$CERN_CE_HOST:2170\/mds-vo-name=resource,o=grid”
<\/span>
* Execute yaim to refresh your sBDII services<\/p>\n

* View the \/opt\/glite\/etc\/gip\/site-urls.conf file to validate that the information was populated with the correct values.<\/p>\n

NOTE:
\n Ensure that the distinguished name (DN) is syntactically correct. Probe
\n the \/opt\/glite\/var\/tmp\/gip\/log\/site-urls.conf log directory to confirm
\nerror free configuration. <\/p>\n

3.<\/strong> Configuration of Top BDII <\/p>\n

Finally, add a entry into the bdii.conf so that the second computing element appears in the information index<\/p>\n
