Setting up Secondary Master Host on Platform LSF


To setup Secondary Master Host on Platform LSF can be very easy.

Step 1: Update the LSF_MASTER_LIST parameter in lsf.conf by updating the current master host

# cd $LSF_ENVDIR
# vim lsf.conf

At line 114

.....
LSF_MASTER_LIST="h00 h01"
.....

If you wish to switch the order of Master Host for maintenance, it can be done as well

Step 2: Reconfigure the cluster and restart the LSF mbatchd and mbschd processes

# lsadmin reconfig
# badmin mbdrestart

Step 3: Update the master_hosts in lsb.hosts

# cd $LSF_ENVDIR/lsbatch/yourhpclcuster/configdir/configdir
# vim lsb.hosts
Begin HostGroup
GROUP_NAME    GROUP_MEMBER      #GROUP_ADMIN # Key words
master_hosts      (h00 h01)
End HostGroup
