Chapter 4
Working with Hosts
Adding dynamic hosts in a shared file system
If the new dynamically added hosts share the same set of configuration and
binary files with normal hosts, you only need to start the LSF daemons on that
host and the host is recognized by the master as an LSF host.
New installation 1 Specify the installation options in install.config.
The following parameters are required:
❖ LSF_TOP="/path"
❖ LSF_ADMINS="user_name [user_name ...]"
❖ LSF_CLUSTER_NAME="cluster_name"
Existing
installation
❖ LSF_MASTER_LIST="host_name [host_name ...]"
List the hosts that are candidates to become the master host for the
cluster.
2 Use lsfinstall -f install.config to install LSF.
1 On the master host, configure the following parameters:
❖ lsf.conf:
✧ LSF_MASTER_LIST="host_name [host_name ...]"
List the hosts that are candidates to become the master host for the
cluster.
✧ LSF_DYNAMIC_HOST_TIMEOUT=timeout[m | M] (optional)
Set an optional timeout value in hours or minutes. If the dynamic
host is unavailable for longer than the time specified, it is removed
from the cluster. To specify a value in minutes, append “m” or “M”
to the timeout value.
❖ lsf.cluster.cluster_name (optional)
✧ LSF_HOST_ADDR_RANGE=IP_address ...
2 Log on as root to each host you want to join a cluster.
3 Use one of the following to set the LSF environment:
❖ For csh or tcsh:
% source LSF_TOP/conf/cshrc.lsf
❖
For sh, ksh, or bash:
$ . LSF_TOP/conf/profile.lsf
4 Optionally, run hostsetup on each LSF server host.
You only need to run hostsetup if you want LSF to automatically start
when the host is rebooted. For example:
# cd /usr/share/lsf/5.1/install
# ./hostsetup --top="/usr/share/lsf" --boot="y"
For complete hostsetup usage, enter hostsetup -h.
5 Use the following commands start LSF:
# lsadmin limstartup
# lsadmin resstartup
# badmin hstartup
