Initiating discovery
After preparing your deployment for discovery, you initiate an
IP Availability Manager
discovery for eachIP Availability Manager
application in the deployment. Then, you initiate a discovery by adding eachIP Availability Manager
as a topology source to. provides two options for adding an
IP Availability Manager
as a topology source. - Option 1 (Recommended): Specify the name of theIP Availability Managerin the domain.conf file.EachIP Availability Managerspecified in the domain.conf file is automatically added as a topology source when starts up.
- Option 2: Manually add theIP Availability Manageras a topology source using the Add Source command.A user attaches theGlobal Consoleto and issues an Add Source command for eachIP Availability Managerthat is to be added as a topology source.Using either option will cause to import device topology from theIP Availability Managersources and to initiate its own discovery. Option 2 can be used at any time to add an additionalIP Availability Manageras a topology source.You can combine Option 1 with Option 2 or use just one of the options to addIP Availability Managersources to. The Comparison of discovery initialization Options 1 and 2 table compares the two options.
Option 1: Automatically added sources (Recommended) | Option 2: Manually added sources |
|---|---|
A user needs to specify the IP Availability Manager sources in the domain.conf file before starting. | A user can add an IP Availability Manager source at any time without restarting. |
Whenever is restarted, it adds as topology sources only theIP Availability Manager s specified in the domain.conf file. | Whenever is restarted, it does not add as topology sources theIP Availability Manager sources previously added using the Add Source command. |
When an IP Availability Manager is not running, proceeds as follows:
| When an IP Availability Manager is not running, invoking the Add Source command to add theIP Availability Manager as a topology source will fail. |
Adding an
IP Availability Manager
as a topology source causes to start a probe that:- Creates an InChargeDomain object having the instance name of theIP Availability Managerapplication.
- Starts a synchronization program that probes theIP Availability Managerrepository for device topology.Thereafter, at startup or whenever the connection to theIP Availability Manageris lost and then re-established, automatically runs this probe.
