Initiating an incremental topology split

To initiate an incremental topology split:
  1. Configure the
    as follows:
    • Enable topology split
      Set 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 mode
        Ensure that the IsTrialLearningEnabled configuration parameter is FALSE.
      • Select incremental topology split
        Ensure that the IsSplitFromScratch configuration parameter is FALSE.
      • Optional but recommended: Enable automatic topology synchronization
        Set the IsTopoSyncEnabled configuration parameter to TRUE.
      • Optional but recommended: 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.
  2. 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
  3. If IsTopoSyncEnabled is TRUE: 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
  4. If IsTopoSyncEnabled is FALSE: For each
    IP Availability Manager
    , use the associated seed file in the
    ’s local/logs directory to manually initiate a discovery at the
    IP Availability Manager
    . If the
    IP Availability Manager
    is on a different host, copy the associated seed file to that host and place it in the BASEDIR/smarts/local/conf directory.
  5. After the
    IP Availability Manager
    s have completed their discoveries, check all critical numbers to determine if they meet your predefined criteria.
