Environment

Novell Open Enterprise Server 11 (OES 11)
Novell Open Enterprise Server 2 (OES 2)
Novell Open Enterprise Server 1 (OES 1) Support Pack 2 Linux

Situation

There are several reasons you may want to recreate the clstrlib.conf file.
For example:
1. You change the admin password and need to have the clstrlib.conf reflect this change.
2. The LDAP server has changed so you need to use a new IP address.
3. You want to add an additional LDAP server.
4. The file may be corrupt.

Resolution

OES 1
Save the following lines in a python script called /opt/novell/ncs/bin/fixclstrlib.py

import clstrlibss
c = clstrlibss.data()
c.ldapUrl = 'ldaps://' + '151.155.247.116' + ':' + '636'
c.adminDn = 'cn=admin,o=novell'
c.adminPw = 'novell'
c.clusterDn = 'cn=wss-linux-cluster,o=novell'
clstrlibss.save(c)

Edit the information in single quotes to match your cluster setup - double check for accuracy.
Then run "python fixclstrlib.py" which will over-write the current clstrlib.conf file; you should make a backup first.


OES 2 and OES 11
1. Create a text file with configuration information. The following is the content of a sample file. The directives are self-explanatory.

CONFIG_NCS_CLUSTER_DN="cn=cluster.o=novell"
CONFIG_NCS_LDAP_IP="151.155.50.100"
CONFIG_NCS_LDAP_PORT="636"
CONFIG_NCS_ADMIN_DN="cn=admin.o=novell"
CONFIG_NCS_ADMIN_PASSWORD="novell"

2. Run command "/opt/novell/ncs/install/ncs_install.py -l -f configuration_file_name"
3. Delete the configuration file because it has your admin password in clear text.

If you have multiple LDAP servers, the syntax is slightly different. Here is an sample.

CONFIG_NCS_CLUSTER_DN="cn=cluster.o=novell"
CONFIG_NCS_LDAP_INFO="ldaps://151.155.50.100:636,ldaps://151.155.50.101:636"
CONFIG_NCS_ADMIN_DN="cn=admin.o=novell"
CONFIG_NCS_ADMIN_PASSWORD="novell"

Starting in the January 2010 version of Novell Cluster Services we use the local server IP address (from /etc/hosts) as the LDAP server.
The text file should have the following entries

CONFIG_NCS_CLUSTER_DN="cn=cluster.o=novell"
CONFIG_NCS_ADMIN_DN="cn=admin.o=novell"
CONFIG_NCS_ADMIN_PASSWORD="novell"

After running the ncs_install.py command you can manually modify the clstrlib.conf file to point to a different LDAP server.

OES2 SP3
Same steps as in OES2 with the following improvement.
You can now specify the LDAP server using the "CONFIG_NCS_LDAP_INFO" line.
Single LDAP Server
CONFIG_NCS_CLUSTER_DN="cn=cluster.o=novell"
CONFIG_NCS_ADMIN_DN="cn=admin.o=novell"
CONFIG_NCS_ADMIN_PASSWORD="novell"
CONFIG_NCS_LDAP_INFO="ldaps://192.168.1.1:636"

Multiple LDAP Servers
CONFIG_NCS_CLUSTER_DN="cn=cluster.o=novell"
CONFIG_NCS_ADMIN_DN="cn=admin.o=novell"
CONFIG_NCS_ADMIN_PASSWORD="novell"
CONFIG_NCS_LDAP_INFO="ldaps://192.168.1.1:636,ldaps://192.168.1.2:636,ldaps://192.168.1.3:636"
