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/scripts/install_node /opt/glite/yaim/etc/USC-LCG2-site-info.def lcg-CE_torque glite-BDII -->
    • /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/scripts/configure_node /opt/glite/yaim/etc/USC-LCG2-site-info.def lcg-CE_torque BDII_site -->
    • /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
  • 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/scripts/install_node /opt/glite/yaim/etc/USC-LCG2-site-info.def glite-SE_classic glite-MON=-->
    • /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/scripts/configure_node /opt/glite/yaim/etc/USC-LCG2-site-info.def SE_classic MON=-->
    • /opt/glite/yaim/bin/yaim -c -s /opt/glite/yaim/etc/USC-LCG2-site-info.def -n SE_classic
<!-- * Check that in file
  • /opt/glite/etc/glite-apel-publisher/publisher-config-yaim.xml
the variable publishGlobalUserName is set to yes

Host certificate update

  • Do not forget to copy the certs in the MON to:
      /opt/glite/var/rgma
    and restart the necessary services. -->

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.
