Configure host groups


  1. Log in as the LSF administrator to any host in the cluster.
  2. Open lsb.hosts.
  3. Add the HostGroup section if it does not exist.
    Begin HostGroup
    groupA            (all)
    groupB            (groupA ~hostA ~hostB)
    groupC            (hostX hostY hostZ)
    groupD            (groupC ~hostX)
    groupE            (all ~groupC ~hostB)
    groupF            (hostF groupC hostK)
    desk_tops         (hostD hostE hostF hostG)
    Big_servers       (!)
    End HostGroup
  4. Enter a group name under the GROUP_NAME column.

    External host groups must be defined in the egroup executable.

  5. Specify hosts in the GROUP_MEMBER column.

    (Optional) To tell LSF that the group members should be retrieved using egroup, put an exclamation mark (!) in the GROUP_MEMBER column.

  6. Save your changes.
  7. Run badmin ckconfig to check the group definition. If any errors are reported, fix the problem and check the configuration again.
  8. Run badmin mbdrestart to apply the new configuration.
