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
