Console Commands for BCC
Novell
®
Business Continuity Clustering (BCC) provides server console commands to help you
perform certain BCC management tasks. Some of the commands can also be used to manage Novell
Cluster Services
TM
clusters.
IMPORTANT: For Novell Cluster Services console commands, see “ Console Commands for
Novell Cluster Services ” in the OES 2 SP2: Novell Cluster Services 1.8.7 for Linux Administration
Guide .

A.1 Using Console Commands
Table A-1 lists the server console commands for managing a business continuity cluster and gives a
brief description of each command.
To execute a cluster console command, enter
cluster
followed by the command. For example, if
this cluster belongs to a business continuity cluster, and you want to see this cluster’s peer clusters,
enter
cluster view
at the server console. You can also enter
cluster help
at the console prompt
to get information on the commands and their functions.
IMPORTANT: You must be logged in as the
root
user, or any other user in
admin
or
ncsgroup
.
Some commands prompt the user for input. When using the command in a script, the prompt is not
needed. You can use the
--noprompt
option for the command to bypass the prompted interaction.
For example, the
cluster migrate
command prompts the user to specify whether to continue
migration if the cluster is experiencing connection issues. When you use the
cluster migrate
command in a script, add the
--noprompt
option to the command line to skip the prompt:
cluster migrate --noprompt [ source/resource ] [ destination/nodename ]
