Building an HA Cluster Configuration
Configuring the Cluster
Chapter 5 247
Package versus Cluster Roles
Package configuration will fail if there is any conflict in roles between
the package configuration and the cluster configuration, so it is a good
idea to have the cluster configuration file in front of you when you create
roles for a package; use cmgetconf to get a listing of the cluster
configuration file.
If a role is configured for a username/hostname in the cluster
configuration file, do not specify a role for the same username/hostname
in the package configuration file; and note that there is no point in
assigning a package administration role to a user who is root on any
node in the cluster; this user already has complete control over the
administration of the cluster and its packages.
Adding Volume Groups
Add any LVM volume groups you have configured to the cluster
configuration file, with a separate VOLUME_GROUP entry for each
cluster-aware volume group that will be used in the cluster. These
volume groups will be initialized with the cluster ID when the
cmapplyconf command is used. In addition, you should add the
appropriate volume group, logical volume and filesystem information to
each package that activates a volume group; see vg on page 303.
NOTE If you are using CVM disk groups, they should be configured after cluster
configuration is done, using the procedures described in “Creating the
Storage Infrastructure with Veritas Cluster Volume Manager (CVM)” on
page 262. Add CVM disk groups to the package configuration file; see
cvm_dg on page 303.
