nodes
After you create a node definition file for your cluster, you can define the nodes to
CSM using the following command:
# definenode -f /tmp/nodedefs
After the definenode command runs, the management server is set up with all
the node information for CSM, and you are ready to verify the node definitions.
Since the actual node installation has not happened yet, you can make changes
to any of the node definitions at this time. To determine whether the nodes have
been defined, enter the lsnode command from the management server.
After you run the lsnode command, the system responds with a line for each
node that was successfully defined. If a node is not defined, it does not appear in
the output for the lsnode command.
To display all the information about each node, use the lsnode command from
the management server with the –l (lowercase L) option, such as:
# lsnode -l
The system responds with a list (output) that contains the extended information
for each node that was successfully defined. If a node is not defined, it does not
appear in the output for the lsnode command.
Some of the attributes for a node may have null values at this point. If a node is
not defined, it is not installed. If you must correct the information, you can change
the attributes of the nodes either by running the chnode command, or by
rerunning the definenode command with the -m (modify) flag. The definenode -m
command accepts a new nodedef file or a new command line and only modifies
nodes that have changed attributes. To change attribute values of a node, enter
the chnode command from the management server:
chnode hostname attr=value
Setting up the installation environment
After you successfully define the node, configure how the node is to be installed
in the cluster. For Red Hat AS or Red Hat EL 3 installations, use Kickstart, and
run the csmsetupks command. For SUSE LINUX Enterprise Server installations,
use AutoYaST, and run the csmsetupyast command. The csmsetupks and
csmsetupyast commands configure the install process, collect MAC addresses,
and configure the network boot of the nodes.
