HP Insight Control for Linux 6.0 User Guide

3 Discovering managed systems, switches, and enclosures
This chapter addresses the following tasks, which you must complete in the following order
when you are configuring and setting up HP Insight Control for Linux:
1. “Discovering systems ” (page 37)
2. “Assigning HP Insight Control for Linux licenses to discovered systems” (page 40)
3. “Preparing and discovering switches and enclosures” (page 41)
4. “Changing the boot method” (page 42)
3.1 Discovering systems
Before a server can be managed and monitored by HP SIM or HP Insight Control for Linux, it
must first be discovered. Discovery is the process of finding servers in the management domain
so that they can be managed from the CMS.
NOTE:
To discover or identify a server that will become a managed system, HP SIM requires that the
SNMP read community string must be set to public in the global credentials for that server.
The value public is the default value. Use the Options→Security→Credentials→Global
Credentials menu item to verify or set this parameter.
There may be additional read community string settings in addition to public, but public
must be specified. If you need to add another read community string, select Add to add another
one, but do not remove public.
The system discovery process depends on whether the server is currently installed with a
supported Linux OS (a running system) or not. Discovery also depends on whether PXE or virtual
media will be used to boot the server.
Use the appropriate procedure to discover systems:
• “Discovering bare-metal servers using PXE” (page 37)
• “Discovering bare-metal servers using virtual media” (page 39)
• “Discovering running systems ” (page 40)
