Configuration
Before invoking a topology split, a user edits a file named topo-split.conf to specify the names of the domains into which the topology will be split, and edits a file named tsm.conf (or invokes dmctl commands) to control
the following aspects of the topology split:
- Enable the topology splitThe associated configuration parameter is NumberOfDomains (Default: 1).
- Select an operating mode for the topology split: normal mode or trial learning modeThe associated configuration parameters are:
- IsTrialLearningEnabled (Default: FALSE)
- NumberOfTrials (Default: 3)
- Configure operating features for the topology splitThe associated configuration parameters are:
- IsSplitFromScratch (Default: TRUE)
- IsTopoSyncEnabled (Default: FALSE)
- EnableAutoEdgeManagement (Default: FALSE)
- IsTSMHookEnabled (Default: FALSE)
- Fine tune the topology-split algorithmThe associated configuration parameters are:
- AdapterHighWaterMark (Default: 100000)
- DeviceHighWaterMark (Default: 5000)...
- NumberOfRetries (Default: 3)By default, topology split is disabled because the default value of the NumberOfDomains configuration parameter is 1. To enable topology split, a user must set NumberOfDomains to the number of domains that are specified in the topo-split.conf file. That number must be greater than 1.The tsm.conf file and the topology-split configuration parameters are described in“Description of tsm.conf” on page 52. The topo-split.conf file and the “DOMAINNAME” configuration parameter are described in“Description of topo-split.conf” on page 59.Chapter 2, Configuring the Topology Split Manager, identifies the configuration tasks in a deployment and provides the procedures for completing those tasks.
