HP Insight Control Software for Linux - Manual (Page 211)

Corrective Actions Cause/Symptom
• Verify that the /etc/opt/mx/config/
RootTrustList.txt
file contains the address of
the CMS and the management hubs.
• Ensure that the /opt/hptc/database/etc/ssl
file on the CMS and management hubs contains the
following:
certfile.pem
keyfile.pem
•
Ensure that Trusted Certificates from HP SIM have at
least one certificate for Insight Control for Linux.
Ensure that the output of the
Options
→Security→Credentials→Trusted Systems…
task matches the values in certfile.pem.
•
Use the grep command for the text endpoint in the
following files:
/opt/hptc/database/lib/sim/
MxpiMainService.pm
/opt/hptc/perl/lib/raapisRPCService.pm
Also verify the IP address for the CMS and port 50002
in those files.
Rerun the operation. The second or third attempt should
work. Root cause:Error connecting to MP at IP address: Read
timed out.
Many Insight Control for Linux operations require
connecting to an iLO. On rare occasions, you might see
this intermittent read time out error. Ensure that the iLO was upgraded to the latest available
iLO firmware.
See “Resolving host names on the CMS” (page 79) Managed System's name changes in HP SIM
The displayed name of a managed system changes to
another name or to localhost, which can cause
connection problems and Nagios failures. Often, this
situation is the result of multiple NICs.
25.7 Troubleshooting DHCP problems
The following table describes possible causes of problems with Dynamic Host Configuration Protocol
(
DHCP ) and provides actions to correct them.
Corrective actions Cause/Symptom
Perform the appropriate action: DHCP Process Not Running
The DHCP server process is absent from the process list,
verified with the following command: •
Verify that the /etc/dhcpd.conf service configuration
file exists and that it is not empty.
• Verify that the /etc/dhcpd.conf service configuration
file is valid. Verify it against the output of the examples
in dhcpd.conf(5). # ps –ef | grep dhcp
• Verify that DHCP is configured to serve IP addresses on
the correct network interface. Compare the output of
the ifconfig command and the contents of the /etc/
sysconfig/dhcpd
file to identify the correct interface.
•
Start the DHCP service with the following command:
# /etc/init.d/dhcpd start
