❖ LSB_SBD_PORT=6882
The port numbers can be any numbers ranging from 1024 to 65535 that are not
already used by other services. To make sure that the port numbers you supply are
not already used by applications registered in your service database, check
/etc/services.
To change the port numbers:
a Shut down your cluster.
b Edit LSF_CONFDIR/lsf.conf.
c Restart LSF.
4 LSF daemons
not responding
After starting the LSF daemons, use the ps command to check that LSF is running on
all LSF hosts, and
mbatchd is running on the master host. mbatchd is started
automatically by
sbatchd on the master host. You never need to start mbatchd
yourself.
Before using any LSF commands, wait a few minutes
lim on all hosts to do the
following:
◆ Contact each other
◆ Select a master host
◆ Exchange initialization information
Check the daemon error logs. Most common problems are:
◆ LSF service port conflicts:
Check that the ports for
lim and res are not used by any other process, and are set
correctly in one of:
❖ LSF_CONFDIR/lsf.conf
❖ /etc/services
❖ NIS
and are not used by any other process.
A common mistake is a typo in port names in
LSF_CONFDIR/lsf.conf.
By default, the following ports are defined in
LSF_CONFDIR/lsf.conf:
❖ LSF_LIM_PORT=6879
❖ LSF_RES_PORT=6878
❖ LSB_MBD_PORT=6881
❖ LSB_SBD_PORT=6882
