Enabling topology split

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:

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
            
```
Find the following line:
```
NumberOfDomains = 1
```
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.
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>
            
```
