HP Systems Insight Manager - Manual (Page 46)

NOTE: If discovery tasks are run out of order, errors are likely. Typical errors due to running
discovery tasks in an improper order include:
• Association errors For example, a server not associated with a management processor or
virtual machine not associated with a virtual machine host.
• Credentials errors Because discovery of systems can trigger additional discovery of associated
systems or management processors, if the correct credentials are not supplied for the associated
systems, their discoveries are likely to show errors. If you discover these associated systems
with a subsequent discovery task containing the proper credentials, they should then complete
successfully.
NOTE: Citrix Xen VMs discovered in category 5 will always return a discovery error unless the
Citrix Xen Host has been registered through Configure
→Virtual Machine→Register Virtual
Machine Host .
If you have a small network, an alternate way of setting up your discovery tasks is to create a
single task with one IP address range and all of the required credentials for the systems in that
range. However, doing this can make it difficult to troubleshoot and diagnose errors if one or more
systems are not configured correctly.
Options on the Discovery page
Under the For all automatic discoveries section, the following options are available:
• Configure general settings Select this option to configure general settings that apply to all
discovery tasks.
• Manage hosts files Select this option to manage hosts files
• Configure global protocol settings Select this option to configure global protocol settings.
NOTE: To discover clusters correctly, you must enable SNMP with the correct security settings
on HP SIM on the target systems.
From the Discovery page, you can:
• Create a new discovery task Click New and the New Discovery section appears.
• Edit an existing discovery task Select a task from the table,and click Edit. The Edit Discovery
section appears.
• 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.
• Delete an existing discovery task Select a task from the table and click Delete.
• View Task Results This button displays the task results for the current discovery task.
• 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.
• Stop a discovery task from running Select the running task and click Stop.
See the Systems Insight Manager online help for more information on each of these options.
Discovery credentials
One of the best ways to configure credentials for your managed systems is to do so as part of a
discovery task. You can enter one or more sets of credentials. As each system is discovered, the
credentials listed in the discovery task will be tried on it, in order, until one set is found to work.
