Configuring automatic discovery
When you access the Automatic tab on the Discovery page, a table displays a listing of all available
discovery tasks. You can configure multiple instances of discovery with each instance having its own schedule
and set of inclusion ranges. When a discovery task is executed, the Last Run column is updated to display
its progress, including the percent complete.
NOTE: Automatic discovery and percent complete are calculated by weighting two factors. First, a ping
sweep is performed on each host, which counts as 10% of the process. Second, the identification process
counts as 90% of the process. (If no host was found on that IP, the 90% part is considered complete.) For
example, if you have 100 hosts in your discovery range and 50 have been pinged, but only 10 have been
identified, you have: 50/100 * .10 = 0.05 (ping sweep) 10/100 * .90 = 0.09 (identification) 0.05 +
0.09 = 0.14 * 100 = 14% (total completed percentage).
NOTE: Only one discovery task can run at a time. If you select to run more than one discovery task, the
percentage in the Last Run column remains at 0% until the currently running task is complete.
Under the For all automatic discoveries section, three options are available:
• Configure general settings Used to configure settings that apply to all discovery tasks. See “Configuring
automatic discovery general settings” for more information.
• Manage templates Used to manage discovery templates. See “Managing discovery templates” for
more information.
• Configure global protocol settings Used to configure global protocol settings. See “Setting global
protocols” for more information.
Note: SNMP must be enabled with correct security settings on HP Systems Insight Manager (HP SIM)
and running on the target systems to discover clusters correctly.
Note: DMI identification is only supported on Windows and HP-UX-based Central Management Server
(CMS) installs. In addition, only like operating systems can be identified. For example, a Windows-based
CMS can identify only Windows-based DMI systems, and an HP-UX-based CMS can identify only
HP-UX-based DMI systems.
Also from the Automatic tab, you can:
• Create a new discovery task Click New and the New Discovery section appears. See “Creating a
new discovery task” for more information.
• Edit an existing discovery task Select a task from the table, and click Edit. The Edit Discovery
section appears. See “Editing a discovery task” for more information.
• Enable or disable a discovery task Select a task and click Disable to disable the schedule of an
enabled task. If a task is disabled, the button changes to Enable. To resume automatic execution of
the task, click Enable. See “Disabling or enabling a discovery task” for more information.
• Delete an existing discovery task Select a task from the table, and click Delete. See “Deleting a
discovery task” for more information.
• Run a discovery task Select the task you want to run, and click Run Now. When a task is running,
the Run Now button changes to a Stop button. See “Running a discovery task” for more information.
NOTE: Two discovery tasks cannot be running at the same exact time. Instead, the second task displays
0% until the first task completes.
• Stop a discovery task from running Select the running task, and click Stop. See “Running a discovery
task” for more information.
