4.6.6 Problems Authenticating to Remote Servers during
Cluster Configuration
If, during the OES cluster installation and configuration, you choose Remote System on the NCS
LDAP Configuration page and you have LDAP configured to point to a NetWare 6.0 or earlier
NetWare server, the cluster configuration will fail. To work around this problem, you must edit the
etc/openldap/ldap.conf
file and either disable certificates (
TLS_REQCERT <level>
line) or change the file that contains the certificates (
TLS_CACERT <filename>
line). See the
ldap.conf man page for more information.
4.6.7 Reconfiguring a Cluster Node
If you want to remove a cluster node from one cluster and add it to another cluster, you must
reconfigure the node.
1 Bring down the cluster node.
2
In eDirectory, delete the cluster node object from the cluster container.
3 In eDirectory, find the NCP Server object and then go to Properties for that object.
This is not the cluster node object in the cluster container. It is the server object for the server.
4 Click Other , then find and delete the NCS:NetWare Cluster attribute.
5 Reconfigure Novell Cluster Services by following the procedure outlined in Section 3.5.3,
“Installing Novell Cluster Services after the OES Installation,” on page 20 .
4.6.8 Device Name Required to Create a Cluster Partition
If you are planning to work with shared-disk NSS Pools and Volumes, you must install a shared-disk
cluster by entering a device name for the cluster Split Brain Detector (SBD) partition at cluster
creation (new cluster) time. If you don't enter a device name, you won't be able to cluster enable
NSS Pools.
4.6.9 Creating a Cluster Partition (SBD Partition) after
Installation
If you did not create a cluster partition during the Novell Cluster Services installation, you can
create one later using the SBDUTIL utility. You must have a shared disk system (a Storage Area
Network or SAN) connected to your cluster nodes before attempting to create a cluster partition. See
Section 3.3, “Shared Disk System Requirements,” on page 18 for more information.
Before creating an SBD partition, you should first make sure one does not already exist on your
shared disk system. To do this, enter
sbdutil -f
at the server console of a cluster node.
If a cluster partition already exists, do not create another one. If a cluster partition does not exist,
enter
sbdutil -c -d device_name
at the server console. Replace device_name with the
name of the device where you want to create the cluster partition.
For example, you might enter something similar to the following:
sbdutil -c -d /dev/sda
See the man page for sbdutil for more information on how to use it.
