This section describes how to change the IP address if the IP address of interconnect is changed after installation of the PRIMECLUSTER system.
Operation Procedure:
Start all the nodes that constitute the cluster system.
If the nodes are already operating, you do not need to restart them.
Stop CF on all the nodes that constitute the cluster system.
For information on how to stop CF, see "4.6 Starting and stopping CF" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."
While referring to the cip.cf file, confirm the CIP name to change the IP address.
For details on the cip.cf file, see "1.2 CIP configuration file" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide" and the manual page describing cip.cf.
For the IPv6 address, edit the cip.cf file and change the IP address corresponding to the CIP name.
When the original address and the modified address are both IPv4, you do not need to change it.
Perform this procedure on all the nodes constituting the cluster system.
Change the IP address of the CIP name that is defined in the hosts(5) file.
Perform this procedure on all the nodes constituting the cluster system.
In the environment where the shutdown agent SA_icmp for VMware environment is used, if the cluster interconnect is used to check whether the node is alive or not, modify /etc/opt/SMAW/SMAWsf/SA_icmp.cfg on each node.

For details, see "H.2.3.3 Setting Up the Shutdown Facility (when using I/O fencing function)."
Start CF on all the nodes constituting the cluster system.
For instructions on how to start CF, see "4.6 Starting and stopping CF" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."
Use the ciptool command to confirm that the IP address of CIP was changed.
# /opt/SMAW/SMAWcf/bin/ciptool -a
