58 Chapter 3:Cluster Software Installation and Configuration
While running cluconfig, you will be prompted as to whether or not you wish to configure a cluster
alias. This appears as the following prompt:
Enter IP address for cluster alias [NONE]: 172.16.33.105
As shown above, the default value is set to NONE, which means that there is no cluster alias, but
the user overrides this default and configures an alias using an IP address of 172.16.33.105. The IP
address used for a cluster alias is distinct from the IP addresses associated with the cluster member’s
hostnames. It is also different from IP addresses associated with cluster services.
3.1.3 Enabling Remote Monitoring
While running cluconfig to specify cluster configuration parameters, the utility will prompt for the
following:
Do you wish to enable monitoring, both locally and remotely, via \
the Cluster GUI? yes/no [yes]:
Answering yes enables the cluster to be locally and remotely monitored by the cluster GUI. This is
currently the only security provision controlling cluster monitoring access. The cluster GUI is only
capable of performing monitoring requests and cannot make any active configuration changes.
Answering no disables Cluster GUI access completely.
3.1.4 Example of the cluconfig Utility
This section details an example of the cluconfig cluster configuration utility, which prompts you for
information about the cluster members, and then enters the information into the cluster database. A
copy of this is located in the cluster.conf file. In this example, the information entered in clu-
config prompts applies to the following configuration:
• On the
storage0 cluster system:
Ethernet heartbeat channels: storage0
Power switch serial port: /dev/ttyC0
Power switch: RPS10
Quorum partitions: /dev/raw/raw1 and /dev/raw/raw2
• On the storage1 cluster system:
Ethernet heartbeat channels: storage1 and cstorage1
Serial heartbeat channel: /dev/ttyS1
Power switch serial port: /dev/ttyS0
Power switch: RPS10
Quorum partitions: /dev/raw/raw1 and /dev/raw/raw2
• IP address to be used for the cluster alias: 10.0.0.154
