HP Serviceguard Version A.11.20 Release Notes, April 2011

Considerations when Upgrading Serviceguard
• .rhosts
If you relied on .rhosts for access in the previous version of the cluster, you must now
configure Access Control Policies for the cluster users. For instructions on how to proceed, see
the subsection “Allowing Root Access to an Unconfigured Node” under “Configuring Root-Level
Access” in Chapter 5 of the Managing Serviceguard manual.
• cmclnodelist
When you upgrade from an earlier version, Serviceguard converts cmclnodelist entries
into new entries written into the cluster configuration file during the upgrade, as follows:
USER_NAME <user_name>
USER_HOST <host_node>
USER_ROLE Monitor
A wildcard + (plus) is converted as follows:
USER_NAME ANY_USER
USER_HOST ANY_SERVICEGUARD_NODE
USER_ROLE Monitor
After you complete the upgrade, use cmgetconf to create and save a copy of the new
configuration. If you do a cmapplyconf, you want to be sure it applies the newly migrated
Access Control Policies.
Considerations when Installing Serviceguard
When you install Serviceguard for the first time on a node, the node is not yet part of a cluster,
and so there is no Access Control Policy. For instructions on how to proceed, see the subsection
“Allowing Root Access to an Unconfigured Node” under “Configuring Root-Level Access” in Chapter
5 of the Managing Serviceguard manual.
