Cluster Configuration Parameters
You need to define a set of cluster parameters. These are stored in the
binary cluster configuration file, which is distributed to each node in the
cluster. You configure these parameters by editing the cluster
configuration template file created by means of the cmquerycl
command, as described under “Configuring the Cluster” on page 172.
The following parameters must be configured:
CLUSTER_NAME
The name of the cluster as it will appear in the output
of cmviewcl and other commands, and as it appears in
the cluster configuration file.
The cluster name must not contain any of the following
characters: space, slash (/), backslash (\), and asterisk
(*).
NOTE In addition, the following characters must not be used
in the cluster name if you are using the Quorum
Server: at-sign (@), equal-sign (=), or-sign (|), semicolon
(;).
These characters are deprecated, meaning that you
should not use them, even if you are not using the
Quorum Server, because they will be illegal in a future
Serviceguard release.
All other characters are legal. The cluster name can
contain up to 39 characters.
