Novell Cluster Services 1.8.2 For Linux; Novell Imanager; Identity Manager - Novell BUSINESS CONTINUITY CLUSTERING 1.1 SP1 - 9-21-2010 ADMINISTRATION GUIDE FOR OPEN ENTERPRISE SERVER 1 SP2 LINUX Administration Manual

2.1.4 Novell Cluster Services 1.8.2 for Linux

You need two to four clusters with Novell Cluster Services™ 1.8.2 (the version that ships with OES
1 SP2) installed and running on each node in the cluster.
Each cluster must have a unique name, even if the clusters reside in different Novell eDirectory
trees, and clusters must not have the same name as any of the eDirectory trees in the business
continuity cluster.
See the OES 1 SP2: Novell Cluster Services 1.8.2 Administration Guide for Linux (http://
www.novell.com/documentation/oes/cluster_admin_lx/data/h4hgu4hs.html)
installing and configuring Novell Cluster Services.

The hardware requirements for Novell Business Continuity Clustering software are the same as
for Novell Cluster Services. For more information, see


Some SAN vendors require you to purchase or license their CLI (Command Line Interface)
separately. The CLI for the SAN might not initially be included with your hardware.
Also, some SAN hardware may not be SMI-S compliant and cannot be managed by using SMI-
S commands.
The recommended configuration is to have each cluster in the same eDirectory tree. You can have a
business continuity cluster with clusters in separate eDirectory trees. See
"Implementing a Multiple-Tree BCC," on page 79
In order to add or change cluster peer credentials, you must access iManager on a server that is in the
same eDirectory tree as the cluster you are adding or changing peer credentials for.

2.1.5 Novell iManager

Novell iManager (the version released with OES 1 SP2) must be installed and running on a server in
the eDirectory tree where you are installing Business Continuity Clustering software. As part of the
install process, you will be installing snap-ins for the Identity Manager role that are management
templates for configuring a business continuity cluster.
The Identity Manager management utilities should be installed on the same server where you have
installed iManager. See "Business Continuity Cluster Component Locations" on page 22
information on where to install Identity Manager components.

2.1.6 Identity Manager

The Identity Manager 2.x or 3.01 engine and the eDirectory driver must be installed on one node in
each Novell Cluster Services for Linux cluster that you want to be in the business continuity cluster.
(Identity Manager was formerly called DirXML
must also be installed. The same Identity Manager installation program used to install the Identity
Manager engine is also used to install the Identity Manager drivers and management utilities.
