Building an HA Cluster Configuration
Preparing Your Systems
Chapter 5 129
Using the cmclnodelist File
The cmclnodelist file is not created by default in new installations. If
administrators want to create this bootstrap file they should add a
comment such as the following:
###########################################################
# Do Not Edit This File
# This is only a temporary file to bootstrap an unconfigured
# node with Serviceguard version A.11.16
# Once a cluster is created, Serviceguard will not consult
# this file.
###########################################################
The format for entries in the cmclnodelist file is as follows:
[hostname or IP address] [user] [#Comment]
For example:
gryf root # Cluster 1,Node 1
gryf user1 # Cluster 1, Node 1
sly root # Cluster 1, Node 2
sly user1 # Cluster 1, Node 2
bit root # Administration /COM Server
In this example, root on the nodes gryf, sly, and bit all have root access
to the node with this file. The non-root user “user1” has the Monitor role
from nodes gryf and sly.
Serviceguard also accepts the use of a “+” in the cmclnodelist file which
indicates that any root user on any node may configure this node and any
non-root user has the Monitor role.
Using Equivalent Hosts
For installations that wish to use hostsequiv, the primary IP addresses or
hostnames for each node in the cluster needs to be authorized. For more
information on using hostsequiv, see man hosts.equiv(4) or the HP-UX
guide, “Managing Systems and Workgroups”.
