Platform LSF Administration Guide Version 6.2

Adding Hosts Dynamically
Administering Platform LSF
108
You only need to run hostsetup if you want LSF to automatically start when the
host is rebooted. For example:
# cd /usr/local/lsf/6.2/install
# ./hostsetup --top="/usr/local/lsf" --boot="y"
For complete hostsetup usage, enter hostsetup -h.
5 Use the following commands start LSF:
# lsadmin limstartup
# lsadmin resstartup
# badmin hstartup
Limitation
The first time a non-shared slave host joins the cluster, daemons on the new host can
only be started on local host. For example, the LSF administrator cannot start daemons
on
hostB from hostA by using lsadmin limstartup hostB. Instead, the first
time the host joins the cluster, use:
# rsh hostB lsadmin limstartup
Allowing only certain hosts to join the cluster
By default, any host can be dynamically added to the cluster. To avoid having
unauthorized hosts join the cluster, you can optionally use
LSF_HOST_ADDR_RANGE in
lsf.cluster.cluster_name to identify a range of
IP addresses to identify hosts that are allowed to be dynamically added as LSF hosts.
LSF_HOST_ADDR_RANGE (lsf.cluster.cluster_name)
If a value is defined for LSF_HOST_ADDR_RANGE, security for dynamically adding
hosts is enabled, and only hosts with IP addresses within the specified range can be
added to a cluster dynamically.
