Mainframe discovery can be initiated through a ServiceNow discovery schedule or by making a copy of the "Schedule Mainframe Discovery" job provided. If you choose to use the ServiceNow discovery schedule to schedule mainframe discovery or start an on-demand discovery, the discovery job will include all probes that are marked as active in the Ironstream Mainframe Probe table. Using the scheduled job method will allow you to schedule discovery of different mainframe components on different schedules. For example, you can create a scheduled job to run discovery of LPAR components each day, and run discovery of other components only once per week.
You should choose either the ServiceNow discovery schedule method or the scheduled job method to initiate discovery, but not both. Using both could produce unexpected results.
