HP Serviceguard A.11.20- Managing Serviceguard Twentieth Edition, August 2011

NOTE: For more information and advice, see the white paper Securing Serviceguard at http://
www.hp.com/go/hpux-serviceguard-docs.
Define access-control policies for a cluster in the cluster configuration file; see “Cluster Configuration
Parameters ” (page 109). You can define up to 200 access policies for each cluster. A root user
can create or modify access control policies while the cluster is running.
Define policies for a specific package in the package configuration file; see the entries for
user_name and related package-configuration parameters (page 253).
NOTE: Once nodes are configured into a cluster, the access-control policies you set in the cluster
and package configuration files govern cluster-wide security; changes to the “bootstrap”
cmclnodelist file are ignored (see “Allowing Root Access to an Unconfigured Node” (page 166)).
Access control policies are defined by three parameters in the configuration file:
• Each USER_NAME can consist either of the literal ANY_USER, or a maximum of 8 login names
from the /etc/passwd file on USER_HOST. The names must be separated by spaces or tabs,
for example:
# Policy 1:
USER_NAME john fred patrick
USER_HOST bit
USER_ROLE PACKAGE_ADMIN
• USER_HOST is the node where USER_NAME will issue Serviceguard commands.
NOTE: The commands must be issued onUSER_HOST but can take effect on other nodes;
for example patrick can use bit’s command line to start a package on gryf.
Choose one of these three values for USER_HOST:
◦ ANY_SERVICEGUARD_NODE - any node on which Serviceguard is configured, and which
is on a subnet with which nodes in this cluster can communicate (as reported
bycmquerycl -w full).
NOTE: If you set USER_HOST to ANY_SERVICEGUARD_NODE, set USER_ROLE to
MONITOR; users connecting from outside the cluster cannot have any higher privileges
(unless they are connecting via rsh or ssh; this is treated as a local connection).
Depending on your network configuration, ANY_SERVICEGUARD_NODE can provide
wide-ranging read-only access to the cluster.
◦ CLUSTER_MEMBER_NODE - any node in the cluster
◦ A specific node name - Use the hostname portion (the first of four parts) of a fully-qualified
domain name that can be resolved by the name service you are using; it should also be
in each node’s /etc/hosts. Do not use an IP addresses or the fully-qualified domain
name. If there are multiple hostnames (aliases) for an IP address, one of those must match
USER_HOST. See “Configuring Name Resolution” (page 168) for more information.
• USER_ROLE must be one of these three values:
◦ MONITOR
◦ FULL_ADMIN
◦ PACKAGE_ADMIN
MONITOR and FULL_ADMIN can be set only in the cluster configuration file and they apply
to the entire cluster. PACKAGE_ADMIN can be set in the cluster configuration file or a package
configuration file. If it is set in the cluster configuration file, PACKAGE_ADMIN applies to all
configured packages; if it is set in a package configuration file, it applies to that package
