3.3.1 Using the Log Consolidation Wizard
The Log Consolidation Wizard is installed as /opt/dsau/sbin/clog_wizard. The wizard
supports creating the following configurations:
• a standalone log consolidation server
• a highly-available log consolidation server for use within a single Serviceguard cluster
(intra-cluster use only)
• a highly-available log consolidation server for use by the local Serviceguard cluster and
remote systems, including Serviceguard cluster clients
• a standalone system forwarding logs to a remote log consolidation server
• a Serviceguard cluster forwarding logs to a remote log consolidation server
Choose the appropriate configuration option.
The wizard detects whether you are running on a standalone system or a Serviceguard cluster.
IMPORTANT: When you run the clog_wizard on a cross-subnet cluster, the system prompts
you to respond to the following question:
Do you want to configure log consolidation? (y/n) [y]:
If you respond with y, the system displays a message indicating that the log consolidation master
server must be an external system outside the cross-subnet cluster, and prompts you to enter
the hostname or the IP address of the log consolidation server.
If the log consolidation server is not configured outside the cross-subnet cluster, then you must
configure an external system, preferably a quorum server, as the log consolidation master server
and later proceed to run the clog_wizard on the cross-subnet cluster node.
When running the wizard on a Serviceguard cluster, the default is to set up clog as a highly
available service (Serviceguard package). The administrator must provision the storage
environment for the package and the required package IP address and DNS name registration.
The wizard supports LVM storage configurations. Non-LVM configurations must be done
manually. The required package information that the wizard requires is listed in the following
table.

3.3.1.1 Configuring a Log Consolidation Standalone Server with clog_wizard
To start the log consolidation wizard, issue the following command:
/opt/dsau/sbin/clog_wizard
For a standalone system, the wizard first displays introductory paragraphs explaining log
consolidation and then asks:
