The requirements in this section must be met prior to installing Novell Business Continuity Clustering software.
Novell Business Continuity Clustering software requires a paper license agreement for each business continuity cluster. For purchasing information, see Novell Business Continuity Clustering.
NetWare® 6.5 Support Pack 5 or 6 (the same as Novell Open Enterprise Server 1 Support Pack 2 for NetWare (OES 2 SP2 NetWare)) must be installed and running on all servers that will be part of the business continuity cluster. When NetWare 6.5 SP6 was released, it replaced SP5 in the OES 1 SP2 NetWare downloads.
IMPORTANT:Novell Business Continuity Clustering 1.1 is not supported on NetWare 6.5 Support Pack 7 (same as Novell Open Enterprise Server 2 for NetWare (OES 2 NetWare)) or later.
Using NetWare 6.5 Support Pack 5 also requires the NetWare 6.5 post Support Pack 5 Update. See OES SP2, NW6.5 SP5 Update 1: TID # 2974185. If you have installed NetWare 6.5 Support Pack 6, the Support Pack 5 Update is not required.
See the NW65 SP8: Installation Guide for information on installing and configuring NetWare 6.5.
Novell eDirectory™ 8.8 is supported with Business Continuity Clustering 1.1 Support Pack 1. See the eDirectory 8.8 documentation for more information.
IMPORTANT:When you install the Business Continuity Clustering engine software, the eDirectory schema is automatically extended in the eDirectory tree where the BCC software is installed. You need to be able to provide the credentials to authorize the schema extension during the install.
The Identity Manager engine and eDirectory driver must be installed on one node in each cluster. The node where Identity Manager is installed must have an eDirectory full replica with at least read/write access to all eDirectory objects that will be synchronized between clusters. This does not apply to all eDirectory objects in the tree.
IMPORTANT:Full eDirectory replicas are required. Filtered eDirectory replicas are not supported with this version of Business Continuity Clustering software.
The eDirectory full replica must have at least read/write access to the following containers:
The Identity Manager driver set container.
The container where the Cluster object resides.
The container where the server objects reside.
If server objects reside in multiple containers, this must be a container high enough in the tree to be above all containers that contain server objects.
Best practice is to have all server objects in one container.
The container where the cluster pool and volume objects are placed when they are synchronized to this cluster. This container is referred to as the landing zone. The NCP server objects for the virtual server of a BCC-enabled resource are also placed in the landing zone.
If the eDirectory full replica does not have read/write access to the containers listed above, cluster resource synchronization and user object synchronization do not work properly.
You need two to four clusters with Novell Cluster Services™ 1.8.2 (the version that ships with NetWare 6.5 Support Pack 5 and 6 (the same as OES 1 SP2 NetWare) 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 NW6.5 SP8: Novell Cluster Services 1.8.5 Administration Guide for information on 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 NW6.5 SP8: Novell Cluster Services 1.8.5 Administration Guide.
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 of a business continuity cluster is to have each Novell Cluster Services cluster be in the same eDirectory tree. You can have a business continuity cluster with clusters in separate eDirectory trees. See Section A.0, Implementing a Multiple-Tree BCC for more information.
You must have the nwcs18pt3 or later cluster patch. See NetWare Cluster Services Field Test: TID # 2974985. This patch can be applied only to NetWare 6.5 Support Pack 5. If you have upgraded to NetWare 6.5 Support Pack 6, this patch is not required.
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.
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 for specific information on where to install Identity Manager components.
The Identity Manager 2.x or 3.0.1 engine and the eDirectory driver must be installed on one node in each Novell Cluster Services cluster that you want to be in the business continuity cluster. (Identity Manager was formerly called DirXML®.) The Identity Manager management utilities 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.
Business Continuity Clustering 1.1 and 1.1 Support Pack 1 support Identity Manager 2.x. Identity Manager 2.0.2 is part of the Identity Manager 2 Bundle Edition (formerly referred to as a Starter Pack) that is included with OES 1 SP2. For installation instructions, see
Installing Identity Manager on NetWare in the Novell Nsure Identity Manager 2.0.1 Administration Guide.
NOTE:The Identity Manager 2.0.1 documentation also applies to Identity Manager 2.0.2 and later versions.
Identity Manager 3.0.1 is also supported beginning with Business Continuity Clustering 1.1 Support Pack 1. It is included with the Identity Manager 3.0.1 Bundle Edition. Instructions for installing and configuring the Identity Manager 3.0.1 Bundle Edition can be found with the Identity Manager 3.0.1 Bundle Edition documentation.
The node where the Identity Manager engine and the eDirectory driver are installed must have an eDirectory full replica with at least read/write access to all eDirectory objects that will be synchronized between clusters. This does not apply to all eDirectory objects in the tree. For information about the eDirectory full replica requirements, see Section 2.1.3, Novell eDirectory 8.8.
The Identity Manager management utilities can be installed on a cluster node, but installing them on a non-cluster node is the recommended configuration. The management utilities should be installed on the same server as iManager.
See Business Continuity Cluster Component Locations for specific information on where to install Identity Manager components.
The Business Continuity Clustering installation program is run from a Windows workstation. Prior to running the installation program:
The Windows workstation must have the latest Novell Client™ software installed.
You must be authenticated to the eDirectory tree where the cluster resides.
You must have SLP (Server Location Protocol) set up and configured properly. See
Configuring OpenSLP for eDirectory in the Novell eDirectory 8.7.3 Administration Guide.
OpenWBEM must be running and configured to start in autoexec.ncf. See the OpenWBEM Services Administration Guide for OES.
For the required OpenWBEM patch, see CIMOM Update for NetWare 6.5 SP6 (Technical Information Document # 5004180).
BASH must be installed on all nodes that participate in the business continuity cluster. The BASH shell does not need to be running, only installed.
You must have the latest LIBC patch installed. This is currently libcsp6X. See LIBC Update NetWare 6.5 SP6 9.00.05 (Technical Information Document # 5003460).
The sys:\system\autoexec.ncf file must be modified so that the call to sys:/bin/unixenv.ncf is before the calls to openwbem.ncf and ldbcc.ncf.
For Business Continuity Clustering 1.1 on NetWare, a shared disk system (Storage Area Network or SAN) is required for each cluster in the business continuity cluster. See NW6.5 SP8: Novell Cluster Services 1.8.5 Administration Guide.
For real-time mirroring, link speeds should be 1 GB or better, the Fibre Channel cable length between sites should be less than 200 kilometers, and the links should be dedicated.
Many factors should be considered for distances greater than 200 kilometers, some of which include:
The amount of data being transferred
The bandwidth of the link
Whether or not snapshot technology is being used
