2.1.11 Shared Disk Systems

For Business Continuity Clustering 1.1 on Linux, a shared disk system (Storage Area Network or

Requirements" (http://www.novell.com/documentation/oes/cluster_admin_lx/data/hclznvyg.html)
in the OES Novell Cluster Services 1.8.2 for Linux Administration Guide.

2.1.12 Link Speeds

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
2.2 Installing Novell Business Continuity
Clustering Software
It is necessary to run the Novell Business Continuity Clustering installation program when you want
to:

Install and configure Business Continuity Clustering engine software on the cluster nodes for
the clusters that will be part of a business continuity cluster.
The Business Continuity Clustering for Linux installation installs to only one server at a time.
You must run the installation program on each node of each cluster that you want to be part of a
business continuity cluster.

Install the BCC-specific Identity Manager templates iManager snap-ins on either an OES 1
Linux server or an OES 1 NetWare server.
The templates add functionality to iManager so you can manage your business continuity
cluster. You must have previously installed iManager on the server where you plan to install the
templates.

Uninstall Business Continuity Clustering software.
