Cifs And Cluster Services; Prerequisites - Novell OPEN ENTERPRISE SERVER 2 SP2 - ADMINISTRATION Manual

Virtual server: A cluster-enabled pool and related services that appears to clients as a physical
server but is not associated with a specific server in the cluster. This is the name of the virtual
server as it appears to NCP
CIFS virtual server: A cluster-enabled pool and the Novell CIFS service that appear to CIFS
clients as a physical server but are not associated with a specific server in the cluster. This is the
name of the virtual server as it appears to CIFS clients.
Cluster IP address: Each cluster-enabled NSS pool requires its own static IP address. The IP
address is used to provide access and failover capability to the cluster-enabled pool (virtual
server). The IP address assigned to the pool remains assigned to the pool regardless of which
server in the cluster is accessing the pool.
Load script: A file that contains the cluster resource definition and commands that load
services and load the NSS pool and its volumes for a given cluster resource. Load scripts are
generated by default when you cluster-enable a pool, and are modified by using the Clusters
plug-in for Novell Cluster Services.
Unload script: A file that contains the cluster resource definition and commands that unload
services and dismount the NSS pool and its volumes for a given cluster resource. Unload
scripts are generated by default when you cluster-enable a pool, and are modified by using the
Clusters plug-in for Novell Cluster Services.

8.3 CIFS and Cluster Services

Novell Cluster Services can be configured either during or after OES 2 SP2 installation. In a cluster,
Novell CIFS for OES 2 SP2 Linux, is available only in ACTIVE/PASSIVE mode, which means that
CIFS software runs on all nodes in the cluster. When a server fails, the cluster volumes that were
mounted on the failed server fail over to that other node. The following sections give details about
using Novell CIFS in a cluster environment:
Section 8.3.1, "Prerequisites," on page 56
Section 8.3.2, "Using CIFS in a Cluster Environment," on page 57

8.3.1 Prerequisites
