Maintaining OVO
Changing Hostnames and IP Addresses
560
Verifies that the new IP address and hostname are resolvable on the
management server.
Verifies that the new IP address and hostname are not already used
by other managed nodes.
Verifies that all management server processes including the
database processes are running.
Changes the IP address of hostname in the OVO database.
On managed nodes only:
— if the IP address has changed, ensures that the new IP address is
configured with the OVO agent software.
— if the hostname has changed, ensures that all currently assigned
templates are redistributed.
Updates the OpenView Network Node Manager if required.
Perform the following steps to change the hostname or IP address on the
managed node:
1. Execute the opc_node_change.pl script on the management server:
opc_node_change.pl -oldname -oldaddr \
-newname -newaddr\
[,,...]
where is old fully qualified name of the managed node
where is the old IP address of the managed node
where is new fully qualified name of the managed node
where is the new IP address of the managed node
Depending on the NNM functionality used on the managed node, the
following options need to be specified in addition:
-nnmupdate
if NNM functionality is used on the managed node, the NNM
needs to be updated using the -nnmupdate option. This option
needs the information of the netmask and the Adapter/MAC
address of the managed node. The MAC address can either be
passed by option -macaddr in hexadecimal notation or by a
callback command line utility passed as a parameter to -hook
option.
