System requirements

Installation and configuration

6.1 Before installation

Shutdown LSF on all work load manager (WLM) and launch node (LN) hosts.

Back up the LSF configuration from the conf ($LSF_ENVDIR) directory and any scripts or binary files that you added to the LSF_SERVERDIR directory (for example, customized elims, esubs, stage in pre-scripts, stage in post scripts).

Run rpm -qa| grep lsf to list the currently installed rpm files.

Use yum erase or rpm -evh to unistall the existing LSF packages.
rpm -ev --allmatches -notriggers 'list of filenames as they appear in step 3'

6.2 Installation steps

Download lsf-10.1-522444.ppc64le_csm.bin package

Run lsf-10.1-522444.ppc64le_csm.bin to extract the RPM files. Accept the license agreement when prompted to continue with the file extraction.
lsf-common-10.1-20190614.ppc64le.rpm
lsf-master-10.1-20190614.ppc64le.rpm
lsf-misc-10.1-20190614.ppc64le.rpm
lsf-server-10.1-20190614.ppc64le.rpm
lsf-pythonapi-10.1.0.6.csm.ppc64le.rpm
ibm_smpi-jsm-10.03.00.01rtm3-rh7_20190611.ppc64le.rpm

Use rpm -ivh or yum install commands to deploy the common, server, and master RPM packages. The installation is relocatable (--prefix options supported)

On the work load manager
rpm -ivh lsf-common-10.1-20190614.ppc64le.rpm lsf-server-10.1-20190614.ppc64le.rpm lsf-master-10.1-20190614.ppc64le.rpm

On the launch node
rpm -ivh lsf-common-10.1-20190614.ppc64le.rpm lsf-server-10.1-20190614.ppc64le.rpm

Verify that the installation is successful:
rpm -qa | grep lsf
lsf-server-10.1-20190614.ppc64le
lsf-common-10.1-20190614.ppc64le
lsf-master-10.1-20190614.ppc64le

6.3 After installation

Restore previously backed up LSF conf directory and any customized scripts or binaries in LSF_SERVERDIR

(Optional) Under LSF_TOP:
Rename work.rpmsave to work

Using bash: On each WLM and LN, run the following commands as root:
. /opt/ibm/spectrumcomputing/lsf/conf/profile.lsf
or if you have used the --prefix to define your own LSF_TOP
. /conf/profile.lsf
Start up LSF

6.4 Uninstallation

Shut down LSF on all WLM and LN hosts.
lsf_daemons stop

Back up the LSF conf directory and any customized scripts or binaries as stated in previous steps.

Use yum erase or rpm -evh commands to unistall LSF following the same previous steps.
