ClusterAdmins Section
(Optional) The ClusterAdmins section defines the LSF administrators for the cluster.
The only keyword is ADMINISTRATORS.
If the
ClusterAdmins section is not present, the default LSF administrator is root.
Using
root as the primary LSF administrator is not recommended.
ADMINISTRATORS
Syntax
ADMINISTRATORS=
administrator_name ...
Description
Specify UNIX user names.
You can also specify UNIX user group name, Windows user names, and Windows user
group names.
The first administrator of the expanded list is considered the primary LSF administrator.
The primary administrator is the owner of the LSF configuration files, as well as the
working files under
LSB_SHAREDIR/cluster_name. If the primary administrator
is changed, make sure the owner of the configuration files and the files under
LSB_SHAREDIR/cluster_name are changed as well.
Administrators other than the primary LSF administrator have the same privileges as the
primary LSF administrator except that they do not have permission to change LSF
configuration files. They can perform clusterwide operations on jobs, queues, or hosts
in the system.
For flexibility, each cluster may have its own LSF administrators, identified by a user
name, although the same administrators can be responsible for several clusters.
Use the
-l option of the lsclusters(1) command to display all of the administrators
within a cluster.
Windows domain
◆ If the specified user or user group is a domain administrator, member of the Power
Users
group or a group with domain administrative privileges, the specified user
or user group must belong to the LSF user domain.
◆ If the specified user or user group is a user or user group with a lower degree of
privileges than outlined in the previous point, the user or user group must belong
to the LSF user domain and be part of the Global Admins group.
Windows workgroup
◆ If the specified user or user group is not a workgroup administrator, member of the
Power Users group, or a group with administrative privileges on each host, the
specified user or user group must belong to the Local Admins group on each host.
Compatibility For backwards compatibility, ClusterManager and Manager are synonyms for
ClusterAdmins and ADMINISTRATORS respectively. It is possible to have both
sections present in the same
lsf.cluster.cluster_name file to allow daemons
from different LSF versions to share the same file.
Example
The following gives an example of a cluster with two LSF administrators. The user listed
first, user2, is the primary administrator.
