Novell OPEN ENTERPRISE SERVER 2 SP 2 - CLUSTER SERVICES 1.8.7 FOR LINUX Manual page 145

The pool resides on a disk that has been enabled as Sharable for Clustering. For information,
see Section 10.3.2, "Enabling Sharing on a Device," on page
Each pool resource requires its own static IP address that is in the same IP subnet as the cluster
IP address.
Volumes on cluster-enabled pools do not appear as independent cluster resources. NSS pools are
resources, and the resource's load and unload scripts are automatically generated for them. Each
cluster-enabled NSS pool requires its own IP address. This means that each cluster-enabled volume
does not have an associated load and unload script or an assigned IP address.
When a server fails, any cluster-enabled pools being accessed by that server fail over to other servers
in the cluster. Because the cluster-enabled pool fails over, all volumes in the pool also fail over, but
only the volumes that have been added to the load script are automatically mounted. Any volumes in
the pool that are not in the load script must be mounted manually. For this reason, volumes that you
do not want to fail over should be in separate pools that are not cluster-enabled.
If you want each volume to be its own cluster resource, each volume must have its own pool.
Some server applications don't require NCP client access to NSS volumes, so cluster-enabling pools
and volumes might not be necessary.
IMPORTANT: Before you attempt to cluster-enable an existing pool and its volumes, the pool
should be deactivated and its volumes should be dismounted.
Comment out (or remove) the volume's entry in the /etc/fstab file. The load and unload scripts that
are created when you cluster-enable the pool will be responsible for mounting and dismounting the
volume after the pool is cluster enabled.
1 Start your Internet browser and enter the URL for iManager.
The URL is http://server_ip_address/nps/imanager.html. Replace server_ip_address with the
IP address or DNS name of a server in the cluster that has iManager installed or with the IP
address for Apache-based services.
2 Specify your username and password, specify the tree information, then click Login.
3 In Roles and Tasks, select Storage, then go the Volumes and Pools pages to verify that the
volumes are not mounted and the pool is deactive.
4 In Roles and Tasks, select Clusters, click Cluster Options, then browse to locate and select the
Cluster object of the cluster you want to manage.
5 On the Cluster Options page, click the New link.
6 Specify Pool as the resource type you want to create by clicking the Pool radio button, then
click Next.
7 Type the name of the pool you want to cluster-enable, or browse and select it.
8 (Optional) Change the default name of the virtual Server object.
When you cluster-enable a pool, a Virtual Server object is automatically created and given the
name of the Cluster object plus the cluster-enabled pool. For example, if the cluster name is
and the cluster-enabled pool name is
cluster1
cluster1_pool1_server
9 If Novell CIFS is running on the cluster server and you want to enable it for this pool, specify
the CIFS Virtual Server Name (up to 15 characters), which is the name assigned to the virtual
server for handling CIFS requests.
