Planning your installation

Plan your installation to determine the required parameters for the install.config file.

Choose a primary LSF administrator (owns the LSF and EGO configuration files and log files). For example,
```
LSF_ADMINS="lsfadmin"
```
Choose a shared LSF installation directory. For example,
```
LSF_TOP="/usr/share/lsf"
```
Choose LSF hosts (management host, management candidates, server hosts, and client-only hosts). For example,
```
LSF_ADD_SERVERS="hostm hostb hostc hostd"
LSF_MASTER_LIST="hostm hostd"
LSF_ADD_CLIENTS="hoste hostf"
```
Important: Do not use the name of any host, user, or user group as the name of your cluster.
Choose LSF server hosts that are candidates to become the management host for the cluster, if you are installing a new host to be dynamically added to the cluster. For example,
```
LSF_MASTER_LIST="hosta hostb"
```
Choose a cluster name that has 39 characters or less with no white spaces. For example,
```
LSF_CLUSTER_NAME="cluster1"
```
If you are installing LSF Standard Edition, choose a configuration template to determine the initial configuration of your new cluster. For example,
```
CONFIGURATION_TEMPLATE="HIGH_THROUGHPUT"
```
Select one of the following templates, depending on the type of jobs that your cluster will run:

DEFAULT

Select this template for clusters with mixed workload. This configuration can serve different types of workload with good performance, but is not tuned for a particular type of cluster.

PARALLEL

Select this template for clusters that are running large parallel jobs. This configuration is designed for long running parallel jobs and not for clusters that mainly run short jobs due to the longer reporting time for each job.

HIGH_THROUGHPUT

This template is used for clusters that mainly run short jobs, where over 80% of jobs finish within one minute. This high turnover rate requires LSF to be more responsive and fast acting, but will use more resources as the daemons become busier.

Note: Do not specify the CONFIGURATION_TEMPLATE parameter for LSF Express Edition and Advanced Edition. These editions have their own default configuration templates for all installations.
If you are planning to use IBM® Spectrum LSF Analytics or IBM Spectrum LSF Application Center, set ENABLE_STREAM="Y" to enable LSF event streaming.
If you made any custom changes to your existing esubs, create a backup of these changes.
If you are planning to run an unattended installation, set SILENT_INSTALL="Y" and LSF_SILENT_INSTALL_TARLIST="ALL | Package_Name ...". The silent installation is a non-interactive installation without any input and output. Installation log files show output and error messages during the installation.
If you are planning to run a quiet installation, set LSF_QUIET_INSTALL="Y". The quiet installation shows all messages but does not prompt for confirmations.
