Template configuration-description files are provided with DSAU that
include examples of the common files that need to be synchronized in a
Serviceguard cluster.
For additional information on DSAU, refer to the Managing Systems
and Workgroups manual posted at http://docs.hp.com.
Log Consolidation
The Distributed Systems Administration Utilities (DSAU) lets you
configure a highly available log consolidation package. Using the log
consolidator, the data from each member-specific
/var/adm/syslog/syslog.log file can be combined into a single file, similar
to standard syslog forwarding. (Note that the DSAU consolidated log
uses the same format as syslog.log: date/time, hostname, message.)
In addition, member-specific package logs can be consolidated in a single
package-specific consolidated log. This helps the administrator easily
monitor, analyze and troubleshoot cluster members and packages.
The log-consolidation tools also offer increased logging reliability using
TCP as well as UDP transports, and sophisticated log-filtering features.
For additional information on DSAU, refer to the Managing Systems
and Workgroups manual posted at http://docs.hp.com.
Using Command Fan-out
Using DSAU command fan-out tools, you can issue commands
cluster-wide. With the cexec tool, you can issue commands from any
member and target the entire cluster or subsets of members in the
cluster.
