Commands to reconfigure your cluster
After you change parameters in LSF configuration files, you must run commands for LSF to reread the files to update the configuration.
Use the following commands to reconfigure a cluster:
- lsadmin reconfig to reconfigure the lim daemon
- badmin reconfig to reconfigure the mbatchd daemon without restarting
- badmin mbdrestart to restart the mbatchd daemon
- bctrld restart sbd to restart the sbatchd daemon
Note: After you change configuration, most LSF parameters require only reconfiguration (lsadmin reconfig or badmin reconfig). Several LSF parameters require restart (badmin mbdrestart). Which parameters require restart are indicated in the parameter description in the IBM Spectrum LSF configuration reference.
For most LSF parameters, the reconfiguration commands that you use depend on which files you change in LSF. The following table is a quick reference.
| File changed | Command | Result |
|---|---|---|
| hosts | badmin reconfig | Reloads configuration files |
| lsb.applications | badmin reconfig | Reloads configuration files Pending jobs use new application profile definition. Running jobs are not affected. |
| lsb.hosts | badmin reconfig | Reloads configuration files |
| lsb.modules | badmin reconfig | Reloads configuration files |
| lsb.nqsmaps | badmin reconfig | Reloads configuration files |
| lsb.params | badmin reconfig | Reloads configuration files |
| lsb.queues | badmin reconfig | Reloads configuration files |
| lsb.resources | badmin reconfig | Reloads configuration files |
| lsb.serviceclasses | badmin reconfig | Reloads configuration files |
| lsb.users | badmin reconfig | reloads configuration files |
| lsf.cluster.cluster_name | lsadmin reconfig AND badmin mbdrestart | restarts the lim daemon, reloads configuration files, and restarts the mbatchd daemon |
| lsf.conf | lsadmin reconfig AND badmin mbdrestart | Restarts the lim daemon, reloads configuration files, and restarts the mbatchd daemon |
| lsf.licensescheduler | bladmin reconfig lsadmin reconfig badmin mbdrestart |
Restarts the bld daemon, restarts the lim daemon, reloads configuration files, and restarts the mbatchd daemon |
| lsf.shared | lsadmin reconfig AND badmin mbdrestart | Restarts the lim daemon, reloads configuration files, and restarts the mbatchd daemon |
| lsf.sudoers | badmin reconfig | Reloads configuration files |
