Access changes in version A.11.16
Serviceguard version A.11.16 introduces a new access method. Instead
of looking at the cmclnodelist or .rhosts files, Serviceguard will check
the configuration files for an Access Control Policy.
If you want any non-root access to a cluster, you must configure an
Access Control Policy in the cluster configuration or in a package
configuration file.
There is a brief description of policies in “What’s in This Version” above.
For more information about role-based access, see the Managing
Serviceguard manual (http://docs.hp.com/hpux/ha), in the
Serviceguard Manager help (under Configuring Clusters -> Roles), and
in the cluster and package configuration files themselves.
Upgrading Serviceguard
Access policies are not supported in a mixed revision cluster.
If you relied on .rhosts for access, be sure to manually configure policies
for those users.
When you upgrade from an earlier version, Serviceguard converts
cmclnodelist entries into Access Control Policies when every node in
the cluster finishes updating. All are given the role of Monitor in the
cluster configuration file.
After you complete a rolling upgrade, be sure to create and save a copy of
the new configuration, using the cmgetconf command. If an
cmapplyconf is issued, you want to be sure it applies the newly migrated
Access Control Policies.
Newly installed Serviceguard
When you install Serviceguard for the first time on a node, you do not
have a cluster. Without cluster configuration, however, you cannot have
an Access Control Policy.
