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.

3.3.1.1Configuring 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:
