Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual page 49

This is the name you will give the new cluster and the eDirectory context where the new
Cluster object will reside.
You must specify an existing context. Specifying a new context does not create a new context.
Cluster names must be unique. You cannot create two clusters with the same name in the same
eDirectory tree.
Cluster IP Address
The cluster IP address is separate from the server IP address, is required to be on the same IP
subnet as the other servers in the same cluster, and is required for certain external network
management programs to get cluster status alerts. The cluster IP address provides a single point
for cluster access, configuration, and management. A Master IP Address resource that makes
this possible is created automatically during the Cluster Services installation.
The cluster IP address is bound to the master node and remains with the master node regardless
of which server is the master node.
SBD (Split Brain Detector) Partition
If you have a shared disk system attached to your cluster servers, Novell Cluster Services
creates a small cluster partition for the Split Brain Detector (SBD) on that shared disk system.
You can create the SBD partition as part of the first cluster node setup, or any time before you
attempt to install the second node in the cluster by using one of the following procedures:
Section 8.16.3, "Creating a Non-Mirrored Cluster SBD Partition," on page 111
Section 8.16.4, "Creating a Mirrored Cluster SBD Partition," on page 112
IMPORTANT: For each SBD partition, you must have at least 20 MB of free space on a
device that has been initialized and marked as shareable for clustering.
If your cluster
Has no shared devices
Has shared devices, but a device that you want
to use for the SBD partition has not yet been
initialized and marked as shareable for
clustering, or you want to set up the SBD later.
Has shared devices, and you want to create a
single SBD partition. The partition you want to
use has been initialized and marked as
shareable for clustering.
Has shared devices, and you want to create a
mirrored SBD partition for greater fault tolerance.
The partitions you want to use have each been
initialized and marked as shareable for
clustering.
Do this
Accept the default setting of None.
The SBD is not needed.
Accept the default setting of None.
To create an SBD partition after the install, see
Section 8.16.3, "Creating a Non-Mirrored Cluster
SBD Partition," on page
To create a mirrored SBD partitions after the
install, see Section 8.16.4, "Creating a Mirrored
Cluster SBD Partition," on page
Select the device where the SBD partition will be
created and specify the size to use.
For example, the device might be something
similar to sdc
Select the device where the SBD partition will be
created, specify the size to use, and select the
device where you want to create the mirrored
partition.
