Distributed Systems Administration Utilities V1.2 Release Notes for HP-UX 11i v2 September 2006

Consolidated Logging
New Feature – Forwarding ASCII Log Data:
DSAU consolidated logging supports the following actions:
• Consolidation of Serviceguard ASCII package logs
• syslog consolidation
Log consolidation allows faster and simpler analysis of events occurring across a cluster or group of
systems.
New in this release is support for the consolidation of arbitrary ASCII log files. The administrator defines
which ASCII logs to consolidate and defines the appropriate filters for those logs on the log consolidation
server. For more information, refer to the Distributed Systems Administration Utilities User's Guide.
Problems that Have Been Fixed
• When using the Consolidated Logging Wizard in a Serviceguard cluster and choosing to have the
cluster be a log consolidation server, the wizard creates a Serviceguard package named "clog.” If you
then run the wizard and choose to re-configure the cluster to be a log forwarding client, the package
should be deleted. In previous versions of DSAU, the package had to be deleted manually. The wizard
now correctly deletes the package.
• When using the System Log Viewer, which is part of the System Management Homepage, the user
can use the Filter tab to specify the number of lines to read from the end of the file. This can improve
performance when the log file is very large. In previous releases, if the user entered a number larger
than the number of lines in the log file, an incorrect number of lines was displayed. This has been
fixed.
Known Problems and Workarounds
Before using consolidated logging, the syslogd(1M) cumulative patch PHCO_34253 must be applied to
both the consolidation server and to log forwarding clients. This patch fixes a problem where log forwarding
did not work after a system was rebooted. This patch is available from the HP IT Resource Center
(www.itrc.hp.com) patch database. Without the patches, syslogd does not properly forward log messages
at system startup or after system reboots. Specifically, syslogd must be manually restarted after the
network has started before log forwarding will operate correctly.
Command Fanout
New Feature – Broadcast Messages:
A new command, cwall(1M), displays a wall(1M) broadcast message on multiple hosts.
Known Problems and Workarounds
Parallel Distributed Shell (pdsh), Parallel Distributed Copy (pdcp) and the commands based on these
utilities (cexec, ccp, ckill, cuptime, cps) display misleading error messages when the security
environment is not properly configured. For example, if non-interactive ssh is not properly configured,
pdsh and pdcp display error messages such as the following:
pdsh@source_node:target_node:Failed to initiate RCP protocol
pdsh@source_node:target_node:ssh exited with exit code 255
This indicates that pdsh was unable to establish an ssh connection with the remote node. For additional
troubleshooting information, refer to Managing Systems and Workgroups, Chapter 3, Configuring a System.
