LSF Version 7.3 - Platform LSF Configuration Reference

You can use either an IPv4 or an IPv6 format for the IP address (if you define the parameter
LSF_ENABLE_SUPPORT_IPV6 in lsf.conf).
Example hosts file
IPv4 example
192.168.1.1 hostA hostB 192.168.2.2 hostA hostC host-C
In this example, hostA has 2 IP addresses and 3 aliases. The alias hostB specifies the first
address, and the aliases hostC and host-C specify the second address. LSF uses the official
host name, hostA, to identify that both IP addresses belong to the same host.
IPv6 example
3ffe:b80:3:1a91::2 hostA hostB 3ffe:b80:3:1a91::3 hostA hostC host-C
In this example, hostA has 2 IP addresses and 3 aliases. The alias hostB specifies the first
address, and the aliases hostC and host-C specify the second address. LSF uses the official
host name, hostA, to identify that both IP addresses belong to the same host.
