Changing the IP Addresses of Servers in a Cluster
After preparing the cluster resources for the IP address change and stopping Novell Cluster Services
(see
“Changing the IP Addresses of Cluster Resources” on page 107
), you are ready to change the IP
addresses of the servers in the cluster.
1
For each server in the cluster, change the server’s IP address by following the instructions
“
Changing an OES 2 Server’s IP Address
” in the
OES 2 SP2: Planning and Implementation
Guide
.
2
The server IP address changes are not complete until you make those changes known to Novell
Cluster Services and eDirectory. Continue with
“Modifying the Cluster Configuration
Information” on page 108
.
Modifying the Cluster Configuration Information
Before restarting Novell Cluster Services, you must update the cluster configuration information in
Novell Cluster Services and eDirectory with the new IP addresses. You might also need to update
the IP address information for the LDAP server and administrator credentials that the cluster uses in
the new subnet.
1
If the cluster is using a different LDAP server or administrator in the new IP subnet, change the
LDAP server IP address and administrator credentials for the cluster in the Novell Cluster
Services configuration settings.
Follow the procedure in
Section 8.13.1, “Changing the Administrator Credentials or LDAP
Server IP Addresses for a Cluster,” on page 105
.

For each node in the cluster, including that of the master IP address resource, modify the
NCS:
Network Address
attribute of its Cluster Node object.

In iManager, click
Directory Administration

NCS: Network Address
and
Network Address
attributes of its Cluster object to specify the new IP address information.
Both
TCP
and
UDP
addresses need to be replaced.
