Tuning, Troubleshooting, Security, and Maintenance
Changing Hostnames/IP Addresses
7. Reconfigure the ITO management server system with the new
hostname/IP address. For details, see the HP-UX System Manager's
Guide.
To change the host name permanently, run the special initialization
script /sbin/set_parms.
Switching to a name server environment: If moving from a "non-name
server" environment to a "name server" environment, make sure the
name server has the new hostname/IP address available.
8. Restart your ITO management server system.
Restarting and Reconfiguring the System After
Changing a Hostname/IP Address
1. Stop the management server if it is running:
/opt/OV/bin/ovstop opc ovoacomm
2. Start the OpenView Topology Manager Daemon Service:
/opt/OV/bin/ovstart ovtopmd
3. If you changed the hostname, you must also update the ITO subagent
configuration:
rm /etc/opt/OV/share/conf/OpC/mgmt_sv/svreg
touch /etc/opt/OV/share/conf/OpC/mgmt_sv/svreg
opt/OV/bin/OpC/install/opcsvreg -add \
/etc/opt/OV/share/conf/OpC/mgmt_sv/itosvr.reg
To reconfigure additionally installed subagent packages, please refer
to the manuals supplied with these packages.
4. If the netmon process automatically starts up when the system starts
up, stop the netmon process:
/opt/OV/bin/ovstop netmon
5. Remove all entries from the SNMP configuration cache:
/opt/OV/bin/xnmsnmpconf -clearCache
6. Update the creation time of objects contained in the ovtopmd
database. This will cause the objects to reappear in all maps the next
time they are synchronized:
/opt/OV/bin/ovtopofix -U
