Before Installing Serviceguard A.11.17
Before you install Serviceguard A.11.17, you need to make sure that your
cluster has the correct hardware upgrades. On older systems you are
upgrading, ensure that your HP representative reviews the firmware
levels of SCSI controller cards and installs the latest versions.
Access changes in version A.11.16
Serviceguard version A.11.16 introduces a new access method. In
clusters with A.11.16 and A.11.17, Serviceguard will not look at the
cmclnodelist or .rhosts files; instead, 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.
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.
