By default, topology split is disabled.

You can edit the tsm.conf file and enable this feature. The line to be edited is:

NumberOfDomains = 1

To enable topology split:

  1. Go to the TSM_BASEDIR/smarts/bin directory and enter the following command to open the tsm.conf file:

                   sm_edit conf/discovery/topo-split/tsm.conf
                
  2. Find the following line:

    NumberOfDomains = 1
    
  3. Change “1” to the number of domains into which the topology will be split. That number must be equal to the number of domains that are specified in the TSM_BASEDIR/smarts/local/conf/discovery/topo-split/topo-split.conf file.

  4. Save and close the file.

    The modified version of the tsm.conf file is saved to the TSM_BASEDIR/smarts/local/conf/discovery/topo-split directory.

    Or, as an alternative to the preceding procedure, and assuming that the NumberOfDomains parameter is commented-out in the tsm.conf file, use the dmctl utility to set the parameter. Go to the TSM_BASEDIR/smarts/bin directory and issue the following command:

                   dmctl -s
                   <TSM name>
                   put TopoSplit_Manager::TopoSplit-Manager::NumberOfDomains
                   
       <number of domains into which to split the topology>
