Distributed Systems Administration Utilities V1.9 Release Notes for HP-UX 11i v2 March 2008

When a user runs the csync_wizard on a cross-subnet cluster, the system displays a message
indicating that the csync master must be an external system outside the cross-subnet cluster.
Depending on whether the csync master is already configured, one of the following is possible:
• If the csync master is already configured outside the cross-subnet cluster, the system displays
the hostname or the IP address of the csync master.
• If the csync master is not configured outside the cross-subnet cluster, then the user must
configure an external system, preferably a quorum server, as the csync master server and
later proceed to run the csync_wizard on the cross-subnet cluster.
Known Problems and Workarounds
• The csync_wizard supports the -f filename option to allow for non-interactive use. The
input file csync_wizard_input.txt located at /var/opt/dsau/cfengine/tmpdir/
contains the answers to all the questions that the wizard asks during an interactive session.
When configuring configuration synchronization in a Serviceguard cluster, cfengine is
defined to run as a package. The data items specified in the input file include the volume
group and logical volume names for the package. Both of these values must be fully qualified.
For example:
volumegroup:/dev/vgcsync
logicalvolume:/dev/vgcsync/lvol1
• When running the Configuration Synchronization Wizard in a Serviceguard cluster, make
sure your current directory is not on the filesystem associated with the shared storage for
the package. When creating the Serviceguard package, the filesystem is forcibly dismounted
and Serviceguard will inadvertently kill the wizard process since it is preventing the
filesystem from being dismounted.
• During each use, the Configuration Synchronization Wizard creates backups of the current
cfengine configuration in the directory /var/opt/dsau/cfengine/backups. The top
level files in this directory are the most recent backups. Any previous configurations are
saved time-stamped subdirectories named "v_timestamp". These backup directories are never
deleted and can accumulate if the wizard is used many times. HP recommends that you
delete these backup directories periodically.
Consolidated Logging
New Features
Configuring Log Consolidation Server in Cross-Subnet Cluster Environments
In a cluster environment, if all the nodes are within the same subnet, then a server within that
cluster environment can be configured as the log consolidation server.
However, in a cross-subnet cluster environment, the log consolidation server must be an external
system, preferably a quorum server, outside the cross-subnet cluster. A cross-subnet cluster can
be configured only as a log forwarding client, with an external system acting as the log
consolidation master server. After an external system is configured as the log consolidation
master server, the cross-subnet cluster nodes can be configured as log forwarding clients.
When a user runs the clog_wizard on a cross-subnet cluster, the system prompts the user to
respond to the following question:
Do you want to configure log consolidation? (y/n) [y]:
If the user responds with y, the system displays a message indicating that the log consolidation
master server must be an external system, preferably a quorum server, outside the cross-subnet
cluster, and then prompts the user to enter the hostname or the IP address of the log consolidation
server.
