LSF_SERVER_HOSTS

Syntax

LSF_SERVER_HOSTS="host_name ..."

Description

Defines one or more server hosts that the client should contact to find a Load Information Manager (LIM). LSF server hosts are hosts that run LSF daemons and provide loading-sharing services. Client hosts are hosts that only run LSF commands or applications but do not provide services to any hosts.
Important:

LSF_SERVER_HOSTS is required for non-shared slave hosts.

Use this parameter to ensure that commands execute successfully when no LIM is running on the local host, or when the local LIM has just started. The client contacts the LIM on one of the LSF_SERVER_HOSTS and execute the command, provided that at least one of the hosts defined in the list has a LIM that is up and running.

If LSF_SERVER_HOSTS is not defined, the client tries to contact the LIM on the local host.

The host names in LSF_SERVER_HOSTS must be enclosed in quotes and separated by white space. For example:
LSF_SERVER_HOSTS="hostA hostD hostB"

The parameter string can include up to 4094 characters for UNIX or 255 characters for Windows.

Interaction with LSF_MASTER_LIST

Starting in LSF 7, LSF_MASTER_LIST must be defined in lsf.conf. You can use the same list of hosts, or a subset of the master host list, in LSF_SERVER_HOSTS. If you include the primary master host in LSF_SERVER_HOSTS, you should define it as the last host of the list.

If LSF_ADD_CLIENTS is defined in install.config at installation, lsfinstall automatically appends the hosts in LSF_MASTER_LIST to the list of hosts in LSF_SERVER_HOSTS so that the primary master host is last. For example: 
LSF_MASTER_LIST="lsfmaster hostE"
LSF_SERVER_HOSTS="hostB hostC hostD hostE lsfmaster"
LSF_ADD_CLIENTS="clientHostA"

The value of LSF_SERVER_HOSTS is not changed during upgrade.
