You can use the sm_tpmgr command to reload the parameters in the discovery.conf, tpmgr-param.conf, or name-resolver.conf file. A discovery cycle should not be in progress when you issue this command.
After you use the sm_edit utility to make a parameter change in the discovery.conf, tpmgr-param.conf, or name-resolver.conf file, you can use the sm_tpmgr command to make that change known to the Topology Split Manager without the need to restart the Topology Split Manager.
The syntax for the sm_tpmgr command is:
sm_tpmgr -s <TSM name> --load-conf=<configuration filename>
For example:
sm_tpmgr -s INCHARGE-TSM --load-conf=discovery.conf
