6 Discovery
Discovery is the process of finding systems in the management domain so that they can be managed
from the CMS by Systems Insight Manager. Systems Insight Manager can automatically discover
and identify systems attached to the network using information from management protocols such
as SNMP, WMI, WBEM, SSH, and SSL. Create discovery tasks to limit discovery to specific network
segments or IP address ranges, or to control the frequency that each task runs. Use discovery filters
to prevent discovery of unwanted system types.
When you access the Discovery page, a table displays a list 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 percentage of completion.
Automatic discovery and completion percentages are calculated by weighting two factors: the
ping sweep (performed on each host) is 10% of the process; the system identification is 90% of
the process. If no host is found on an IP address, the system identification is considered complete.
For example, you have 100 hosts in your discovery range. If 50 hosts have been pinged, but only
10 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: You can run only one discovery task 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.
Recommended discovery tasks
For best results, HP recommends creating the following discovery tasks, and running them
sequentially in the suggested order. You might want to create multiple tasks for certain types, such
as servers, grouping them so that systems with the same credentials are in the same discovery
tasks, with up to three sets of credentials supplied in each discovery task. This reduces the chance
of account lockout when an invalid credential is tried too many times.
1. Central Management Server (CMS)
This discovery task is for discovery of the Systems Insight Manager CMS and its management
processor, if it has one.
2. Onboard Administrator
This discovery task is for discovery of the Onboard Administrators for every enclosure to be
managed. When specifying credentials for this task, include the iLO credentials for every
blade in the enclosures associated with the Onboard Administrators.
3. Management Processors
This discovery task is for discovery of all management processors not discovered in the previous
tasks. This includes iLOs and management processors for all non-blade systems.
4. Physical Servers
This discovery task is for discovery of physical servers (blade servers and standalone servers).
The management processors for these servers must be discovered prior to this discovery task
being run.
5. Virtual Machines
This discovery task is for discovery of virtual machines associated with servers discovered in
the previous category.
