HP Insight control for Linux 6.2 Installation Guide

3.4.2 CMS configuration requirements
Verify that the CMS meets the configuration requirements for Systems Insight Manager and
Insight Control for Linux described in this section. If the CMS configuration does not meet a
requirement, complete the configuration task or tasks now.
3.4.2.1 Configure a network interface
Before installing Insight Control for Linux, you must configure a network interface on the CMS
for communication with the managed systems. During the Insight Control for Linux installation
process, services and applications are configured using the management network interface, thus
it must be configured before you run the Insight Control for Linux installation script.
For more information about configuring network interfaces, see the vendor-supplied OS
documentation.
3.4.2.2 Configure SNMP
When the CMS is an HP ProLiant server with an iLO-based MP, Section 3.4.1.5 (page 23) instructed
you to install the PSP on it.
Now, enter the following command to configure SNMP on the CMS:
NOTE: Do not configure SNMP if the CMS is a Xen or KVM virtual guest.
# /sbin/hpsnmpconfig
For a sample of the SNMP configuration questions and how to respond, see the related appendix
in the HP Insight Control for Linux User Guide. Typically, you can accept the default responses to
most questions.
3.4.2.3 Modify the CMS entry in the /etc/hosts file
View the CMS information in the /etc/hosts file to ensure that the real host name of the CMS
is not equated to localhost.
Example 3-1 provides an example of the contents of this file. If your /etc/hosts file does not
look similar to the example, modify the file accordingly.
Example 3-1 /etc/hosts file entries for the CMS
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
CMS_IP_address CMS_fq_hostname CMS_hostname
The 127.0.0.1 IP address must be associated with the localhost entry, and the CMS information
cannot appear on the same line with localhost. The CMS IP address, fully qualified host name,
and host name must be on a separate line.
If those entries are not located on a separate line, use a text editor to make the necessary
adjustments.
For example, the /etc/hosts entries for a CMS named earth look like this:
127.0.0.1 localhost.localdomain localhost
192.0.2.5 earth.example.com earth
3.4.2.4 Configure a static IP address
Because managed systems need to know where to report events, ensure that the CMS is configured
with a static, stable IP address. HP does not recommend using DHCP for the CMS.
