Chapter 7 257
Adding Previously Configured Nodes to a Running
Cluster
You can use Serviceguard Manager, or HP Serviceguard commands as
shown, to bring a configured node up within a running cluster.
Use the cmrunnode command to add one or more nodes to an already
running cluster. Any node you add must already be a part of the cluster
configuration. The following example adds node ftsys8 to the cluster
that was just started with only nodes ftsys9 and ftsys10. The -v
(verbose) option prints out all the messages
cmrunnode -v ftsys8
By default, cmrunnode will do network validation, making sure the
actual network setup matches the configured network setup. This is the
recommended method. If you have recently checked the network and find
the check takes a very long time, you can use the -w none option to
bypass the validation.
Since the node's cluster is already running, the node joins the cluster and
packages may be started, depending on the package configuration (see
node_name on page 210). If the node does not find its cluster running, or
the node is not part of the cluster configuration, the command fails.
