LSF Version 7.3 - Platform LSF Configuration Reference

If the LIM has just been started, this is normal, because the LIM needs time to get initialized
by reading configuration files and contacting other LIMs. If the LIM does not become available
within one or two minutes, check the LIM error log for the host you are working on.
To prevent communication timeouts when starting or restarting the local LIM, define the
parameter LSF_SERVER_HOSTS in the lsf.conf file. The client will contact 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.
When the local LIM is running but there is no master LIM in the cluster, LSF applications
display the following message:
Cannot locate master LIM now, try later.
Check the LIM error logs on the first few hosts listed in the Host section of the
lsf.cluster.cluster_name file. If LSF_MASTER_LIST is defined in lsf.conf, check the
LIM error logs on the hosts listed in this parameter instead.
Master LIM is down
Sometimes the master LIM is up, but executing the lsload or lshosts command prints the
following error message:
Master LIM is down; try later
If the /etc/hosts file on the host where the master LIM is running is configured with the
host name assigned to the loopback IP address (127.0.0.1), LSF client LIMs cannot contact the
master LIM. When the master LIM starts up, it sets its official host name and IP address to
the loopback address. Any client requests will get the master LIM address as 127.0.0.1, and try
to connect to it, and in fact will try to access itself.
Check the IP configuration of your master LIM in /etc/hosts. The following IPv4 example
incorrectly sets the master LIM IP address to the loopback address:
127.0.0.1 localhost myhostname
The following example correctly sets the master LIM IP address:
127.0.0.1 localhost
192.168.123.123 myhostname
For a master LIM running on a host that uses an IPv6 address, the loopback address is
::1
An IPv6-enabled host should have the following entries in its /etc/hosts file:
::1 localhost ipv6-localhost ipv6-loopback
fe00::0 ipv6-localnet
ff00::0 ipv6-mcastprefix
ff02::1 ipv6-allnodes
ff02::2 ipv6-allrouters
ff02::3 ipv6-allhosts
RES does not start
Check the RES error log.
On UNIX, if the RES is unable to read the lsf.conf file and does not know where to write
error messages, it logs errors into syslog.
On Windows, if the RES is unable to read the lsf.conf file and does not know where to write
error messages, it logs errors into C:\temp.
