After choosing a trial initial topology split, you should restart the Topology Split Manager with the repository file from that trial and perform an incremental topology split (with topology synchronization, edge management, and TSM hook enabled) to continue with the desired trial result as a starting point.

Here is the procedure for using a trial initial topology split. In the procedure, for simplification purposes, the Topology Split Manager is named INCHARGE-TSM, and the chosen initial topology split is located in the INCHARGE-TSM.trial.002 directory and is named INCHARGE-TSM.rps.

  1. Go to the TSM_BASEDIR/smarts/bin directory and enter the following command to stop the Topology Split Manager:

    For a Topology Split Manager that was started with a service command (sm_service):

                   sm_service stop ic-tsm
                   dmquit -s INCHARGE-TSM
  2. Copy the repository file for the chosen initial topology split to the TSM_BASEDIR/smarts/local/repos/icf directory:

    On a UNIX system:

                   cp /opt/InCharge/TSM/IP/smarts/local/logs/INCHARGE-TSM.trial.002/
                     INCHARGE-TSM.rps  /opt/InCharge/IP/TSM/smarts/local/repos/icf
                   xcopy C:\InCharge\TSM\IP\smarts\local\logs\INCHARGE-TSM.trial.002\
                     INCHARGE-TSM.rps  C:\InCharge\TSM\IP\smarts\local\repos\icf
  3. Enter the following command from TSM_BASEDIR/smarts/bin to start the Topology Split Manager:

    For a service startup command (sm_service):

                   sm_service start ic-tsm
                   sm_server --name=INCHARGE-TSM --config=icf 
                     --bootstrap=bootstrap-tsm.conf --ignore-restore-errors 
                       --noreconfigure --output --daemon
  4. Configure the Topology Split Manager as follows:

    • Enable topology split

      Ensure that the NumberOfDomains configuration parameter is set to the number of domains that are specified in the TSM_BASEDIR/smarts/local/conf/discovery/ topo-split/topo-split.conf file. That number must be greater than 1.

      • Select normal mode

        Ensure that the IsTrialLearningEnabled configuration parameter is FALSE.

      • Select incremental topology split

        Ensure that the IsSplitFromScratch configuration parameter is FALSE.

      • Enable automatic topology synchronization

        Set the IsTopoSyncEnabled configuration parameter to TRUE.

      • Enable edge management

        Set the EnableAutoEdgeManagement configuration parameter to TRUE. Note that automatic topology synchronization must be enabled before edge management can be enabled.

      • Enable the TSM hook script

        Set the IsTSMHookEnabled configuration parameter to TRUE.

  5. Enter the following command from TSM_BASEDIR/smarts/bin to invoke an incremental topology split:

                   dmctl -s <TSM name> invoke GA_Driver::TopoSplit-Driver start
  6. For each IP Availability Manager, go to the BASEDIR/smarts/bin directory in the appropriate IP Manager installation area and enter the following command to invoke a pending discovery:

                   dmctl -s <AM name>    invoke ICF_TopologyManager::ICF-TopologyManager discoverPending
                   dmctl -s AM001 invoke 
                      ICF_TopologyManager::ICF-TopologyManager discoverPending
  7. After the IP Availability Managers have completed their discoveries, check all critical numbers to determine if they meet your predefined criteria.
