HP Operations Manager for UNIX Administrator’s Reference

Maintaining HPOM
Changing Hostnames and IP Addresses
10. Update all managed nodes with the new hostname of the
management server.
Perform the following steps on HTTPS-based managed nodes that
are configured in the Node Bank and which are running an HPOM
agent:
a. Stop all HPOM agent processes on the managed nodes, enter:
/opt/OV/bin/ovc -kill
b. Specify the new hostname of the management server in the
security name space:
/opt/OV/bin/ovconfchg -ns sec.core.auth \
-set MANAGER
c. If the certificate server is located on the same system as the
management server, the CERTIFICATE_SERVER variable must
also be updated. Enter:
/opt/OV/bin/ovconfchg -ns sec.cm.client \
-set CERTIFICATE_SERVER
d. Restart all HPOM agent processes by entering:
/opt/OV/bin/ovc -start
11. Change the primary management server.
If the modified HP Operations management server is configured as a
primary manager for some managed nodes, update those managed
nodes by running the following command from the modified HP
Operations management server:
/opt/OV/bin/OpC/opcragt -primmgr [-all | \
[-nodegrp …] …]
12. Verify and redistribute the templates.
Verify that the templates are still assigned to the managed nodes.
Then redistribute the templates.
13. Update flexible management environments.
• Make sure that your hostname and IP address changes are
reflected in all configurations and templates across the entire
flexible-management environment.
