HP Systems Insight Manager 7.2 Technical Reference Guide

Options for adding a single system
• Know the IP address or host name of the system. If you know at least one of these, HP SIM
can find the other by validating the information with the Domain Name Service (DNS) for the
network.
• To add a cluster and nodes, enter each IP address separately.
• Decide if you want to set the system type, subtypes, or WBEM credentials as well as the
product model.
• Specify the WBEM settings for the system on the System Protocol Settings page. You can
override the default user name and passwords by selecting use values specified below and
entering appropriate user names and passwords.
• Specify the SNMP settings for this system to be unique or match the global discovery settings.
The current system default settings appear. If you override the default and specify a different
value, that community string must be supported on the system. If it is not and one of the defaults
is supported, HP SIM reverts back to the default value. When manually adding a single system,
you can modify the following settings:
The amount of time HP SIM waits for an SNMP response
when it sends a request to the system. The default timeout
timeout
value appears. If a response is not received within time
interval, HP SIM might determine that the system does not
support SNMP. Decreasing this value can cause increased
network traffic because the rate of retry attempts is
increased. Use caution when changing this value. A value
of three seconds usually works for a LAN. However, if
systems are connected through a WAN, try a higher value,
for example, 10 seconds.
The number of additional times after the first attempt is
made to communicate with a system before the attempts
stop.
retries
A community string sets up authentication that enables or
prohibits communication between the managed system
community strings
and the CMS. The CMS community string of the must match
the community string of the managed system. Use the
read-only community string to read variables. Use the write
community string to modify variables. Although only one
community is valid for a communication attempt, a system
can belong to multiple communities. However, HP SIM uses
only one community string when communicating with a
system.
NOTE: If an IP address is used to manually add a single system, it must be properly resolved to
a system name for the name to be displayed in the GUI.
Discovery related information
Configuring automatic discovery
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
