Chapter 15 Serviceguard

To see “live” clusters, from a management station, connect to a Serviceguard node’s Cluster
Object Manager (COM) daemon. (The COM is automatically installed with Serviceguard.)
This node becomes the session server. It goes out over its subnets, and establishes connections
with the COMs on other Serviceguard nodes. The session server relays commands from the
management station to the target nodes, and relays the target nodes’ configuration and status data
back to the management station. It also relays operation messages from the target nodes to the
management station.
If the Session Server node is running Serviceguard versions A.11.13 through A.11.17, the
Serviceguard Security Patch must be installed and enabled before the Session Server node can
connect to cluster nodes running A.11.17.
To connect, you need to specify a valid username and password from the session server’s
/etc/passwd file. List the cluster or clusters you want to see. Click “unused nodes” to see nodes
that are not currently configured into a cluster, but do have Serviceguard installed.
For the session server to get information from a cluster, the target cluster must allow it access.
The target node will resolve the session server’s hostname through /etc/hosts or DNS.
Access method and non-root roles changed in Serviceguard Version A.11.16:
 In clusters with Serviceguard version A.11.16 and later, the cluster configuration file or a
package configuration file, must have an Access Control Policy that specifies this triplet:
the intended user, the COM server’s hostname, and a role of at least Monitor.
 In earlier versions of Serviceguard, the /etc/cmcluster/cmclnodelist file must have this
pair listed: COM server’s host_node, and user root.
