Consolidated Log

(clog)

clog is the name of the Serviceguard package providing high availability for consolidated syslog

and package log files across all nodes in the cluster. It is also the DSAU command for displaying a

specified log file.

DSAU

Distributed System Administration Utilities provides several tools for simplifying the management of

groups of systems and Serviceguard clusters. In Serviceguard, it is used for consolidating syslog

and package logs from all nodes in the cluster to a central location.

Node

A host system or server that is configured to be a member of a Serviceguard cluster

Package

Application services (individual Linux processes) and resources grouped together and managed as a

unit within Serviceguard in the event that a failover is required

Relocatable IP

Address

A virtual IP address that is associated with a Serviceguard package; this type of IP address is not

stationary to a specific node because it can move from one cluster node to another when a package

is moved. Relocatable IP addresses are assigned and removed by Serviceguard.

Serviceguard

Manager

A web-based, HP System Management Homepage (HP SMH) tool used for monitoring,

administering, and configuring Serviceguard clusters.
