Access Control Policies (also known as Role Based Access)
For each policy, specify USER_NAME, USER_HOST, and
USER_ROLE. Policies set in the configuration file of a
cluster and its packages must not be conflicting or
redundant. For more information, see “Access Roles” on
page 204.
FAILOVER_OPTIMIZATION
You will only see this parameter if you have installed
Serviceguard Extension for Faster Failover, a
separately purchased product. You enable the product
by setting this parameter to TWO_NODE. Default is
disabled, set to NONE. For more information about the
product and its cluster-configuration requirements, go
to http://www.docs.hp.com -> High Availability
and choose Serviceguard Extension for Faster Failover.
NETWORK_FAILURE_DETECTION
The configuration file specifies one of two ways to
decide when a network interface card has failed:
• INOUT
• INONLY_OR_INOUT
The default is INOUT.
See “Monitoring LAN Interfaces and Detecting Failure”
on page 100 for more information.
Can be changed while the cluster is running.
Cluster Configuration Worksheet
The following worksheet will help you to organize and record your cluster
configuration. This worksheet is an example; blank worksheets are in
Appendix F.
