Yaim (General)

• Yaimtool is a web utility to generate the VO configuration part of yaim

Computing Element

• Run Yaim to install the necessary software:
  • /opt/glite/yaim/bin/yaim -i -s /opt/glite/yaim/etc/USC-LCG2-site-info.def -m lcg-CE_torque -m glite-BDII -m glite-MON
• Run Yaim to configure the node:
  • /opt/glite/yaim/bin/yaim -c -s /opt/glite/yaim/etc/USC-LCG2-site-info.def -n lcg-CE -n TORQUE_utils -n TORQUE_server -n BDII_site -n MON
• Set up the correct number of processors for machines with 4 cores (lhcb43-lhcb63; Physical or hyperthreaded) or with 8 cores (lhcb64-lhcb88; Physical)
• Restart the following services in the given order:
  • pbs_server (In order to reconfigure the number of avaliable processors for the nodes in pbs queue.)
  • maui (It should be always run after pbs_server.)
  We have to check that this is indeed the order in which these services are started.
• Some more configuration steps necessary when configuring sgm/prod pool accounts
  • SgmPrdPoolAcounts
• Check in file
  • /opt/glite/etc/glite-apel-publisher/publisher-config-yaim.xml
  that the variable publishGlobalUserName is set to 'yes'. This step is taken care by yaim now.

Storage Element

For the time being, edit the file: /opt/glite/yaim/funtions/config_gip and change the line:
GlueInformationServiceURL: ldap://`hostname -f`:2170/mds-vo-name=resource,o=grid
by the line:
GlueInformationServiceURL: ldap://`hostname -f`:2135/mds-vo-name=local,o=grid
this problem is probably related to the line:
BDII_SE_URL="ldap://$CLASSIC_HOST:2135/mds-vo-name=local,o=grid"
in USC-LCG2-site-info.def.

• Run Yaim to install the necessary software:
  • /opt/glite/yaim/bin/yaim -i -s /opt/glite/yaim/etc/USC-LCG2-site-info.def -m glite-SE_classic
• Run Yaim to configure the node:
  • /opt/glite/yaim/bin/yaim -c -s /opt/glite/yaim/etc/USC-LCG2-site-info.def -n SE_classic

Migration of components between nodes

• Do not forget to check that the necessary ports are open in the firewall of the node were we are moving the component to.

• Do not forget to register the new sBDII node in the GOCDB.
