56 Chapter 3:Cluster Software Installation and Configuration
• Number of heartbeat connections (channels), both Ethernet and serial
• Device special file for each heartbeat serial line connection (for example, /dev/ttyS1)
• IP host name associated with each heartbeat Ethernet interface
• IP address for remote cluster monitoring, also referred to as the "cluster alias". Refer to Section
3.1.2, Configuring the Cluster Alias for further information.
• Device special files for the serial ports to which the power switches are connected, if any (for
example, /dev/ttyS0), or IP address of a network attached power switch.
• Power switch type (for example,
RPS10 or None if not using power switches)
• The system will prompt whether or not to enable remote monitoring. Refer to Section 3.1.2,
Configuring the Cluster Alias for more information.
See Section 3.1.4, Example of the
cluconfig Utility for an example of running the utility.
3. After completing the cluster initialization on one cluster system, perform the following tasks on
the other cluster system:
• Run the /sbin/cluconfig --init=
raw_file command, where raw_file specifies the
primary quorum partition. The script will use the information specified for the first cluster sys-
tem as defaults. For example:
cluconfig --init=/dev/raw/raw1
4. Check the cluster configuration:
• Invoke the cludiskutil utility with the -t option on both cluster systems to ensure that
the quorum partitions map to the same physical device. See Section 3.2.1, Testing the Quorum
Partitions for more information.
• If using power switches, invoke the clustonith command on both cluster systems to test
the remote connections to the power switches. See Section 3.2.2, Testing the Power Switches
for more information.
5. Optionally, configure event logging so that cluster messages are logged to a separate file. See
Section 3.3, Configuring syslog Event Logging for information.
6. Start the cluster by invoking the cluster start command located in the System V init
directory on both cluster systems. For example:
service cluster start
After initializing the cluster, proceed to add cluster services. See Section 3.4, Using the cluadmin
Utility and Section 4.1, Configuring a Service for more information.
