Changing Hostnames/IP Addresses
Changing Hostnames/IP Addresses
Frequently, a node has several IP addresses and hostnames. You may
need to change an IP addresses if a node becomes a member of another
sub-net. In this case, the IP address or fully qualified domain name may
change
In general, on HP-UX systems, the IP address and the related hostname
are configured in:
❏ /etc/hosts
❏ the Domain Name Service (DNS), or
❏ the Network Information Service (NIS)
ITO also configures the hostname and IP address of the managed nodes’
management server in the management server database.
If you are moving from a non-name-server environment to a name-server
environment (DNS, BIND), make sure the name server has access to the
new IP address.
Hostnames work within IP networks to identify a managed node. While
a node may have many IP addresses, the hostname is used to pin-point a
specific node. The system hostname is the string returned when you use
the UNIX hostname(1) command.
Changing the Hostname/IP Address of the
Management Server
Change the hostname and/or IP address of the management server in
two stages. Firstly, set up the change by stopping processes and changing
the name. Then, restart and reconfigure ITO for your changes to take
effect. See the following section for information on how to change the
hostname/IP address of the managed nodes.
NOTE You must de-install the ITO agent software from the management server
before changing the hostname of the management server. Re-install the
ITO agent software when you have finished this task. For more
information on de-installing and re-installing the agent software, see the
HP OpenView IT/Operations Installation Guide for the Management
Server.
