2.2.7 Removing Business Continuity Clustering Core Software
If you need to uninstall Novell Business Continuity Clustering, you can do so by using the Business
Continuity Clustering installation program.
1 Using the KDE desktop environment, log in as user
Clustering CD you created into an OES 1 Linux server, and then wait for the Business
Continuity Clustering installation script to launch.
If you are using the GNOME desktop environment instead of KDE, the installation does not
automatically launch. To start the installation, browse the installation CD using My Computer,
double-click the
autorun.sh
2 Deselect the Install Core Business Continuity Clustering 1.1 Software and Configure Core
Software options, select Remove Installed Software, then click Next.
2.3 Configuring File System Mirroring
Several different methods and scenarios exist for mirroring data between geographically separate
sites. Each method has its own strengths and weaknesses. For a Business Continuity Clustering
system, you need to choose either host-based mirroring or SAN-based mirroring (also called array-
based mirroring) and whether you want the mirroring to be synchronous or asynchronous.
SAN-based synchronous mirroring is preferred and is provided by SAN hardware manufacturers.
Host-based synchronous mirroring functionality is included with the NSS file system (NSS
mirroring) that is part of OES 1 Linux.
NOTE: The Business Continuity Cluster 1.1 product does not perform data mirroring. You must
separately configure either SAN-based mirroring or host-based mirroring.
NSS mirroring is a checkpoint-based synchronous mirroring solution. Data blocks are written
synchronously to multiple storage devices. It is an alternative to SAN array-based synchronous
replication options.
IMPORTANT: NSS pool snapshot technology does not work in a business continuity cluster.
