Initiating an incremental topology split
To initiate an incremental topology split:
- Configure the as follows:
- Enable topology splitSet the NumberOfDomains configuration parameter 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 modeEnsure that the IsTrialLearningEnabled configuration parameter is FALSE.
- Select incremental topology splitEnsure that the IsSplitFromScratch configuration parameter is FALSE.
- Optional but recommended: Enable automatic topology synchronizationSet the IsTopoSyncEnabled configuration parameter to TRUE.
- Optional but recommended: Enable edge managementSet the EnableAutoEdgeManagement configuration parameter to TRUE. Note that automatic topology synchronization must be enabled before edge management can be enabled.
- Enable the TSM hook scriptSet the IsTSMHookEnabled configuration parameter to TRUE.
- 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
- If IsTopoSyncEnabled is TRUE: For eachIP Availability Manager, go to the BASEDIR/smarts/bin directory in the appropriateIP Managerinstallation area and enter the following command to invoke a pending discovery:dmctl -s<AM name>invoke ICF_TopologyManager::ICF-TopologyManager discoverPendingdmctl -s AM001 invokeICF_TopologyManager::ICF-TopologyManager discoverPending
- If IsTopoSyncEnabled is FALSE: For eachIP Availability Manager, use the associated seed file in the ’s local/logs directory to manually initiate a discovery at theIP Availability Manager. If theIP Availability Manageris on a different host, copy the associated seed file to that host and place it in the BASEDIR/smarts/local/conf directory.
- After theIP Availability Managers have completed their discoveries, check all critical numbers to determine if they meet your predefined criteria.
