|Oracle Solaris Cluster Geographic Edition System Administration Guide Oracle Solaris Cluster 4.0|
You must be an experienced Oracle Solaris Cluster administrator to administer Geographic Edition software.
This section describes the Oracle Solaris Cluster administration topics that you need to understand before you administer the Geographic Edition software.
You use Oracle Solaris Cluster commands create failover and scalable resource groups.
For more information about administering resources and resource groups in Oracle Solaris Cluster software, see the Oracle Solaris Cluster Data Services Planning and Administration Guide.
The logical hostname is a special high-availability (HA) resource. The geoadm start command configures the logical hostname that corresponds to the cluster name. The IP address and host maps for the logical hostname must be set up before you run this command. Before assigning hostnames, familiarize yourself with the legal names and values that are described in Appendix B, Legal Names and Values of Geographic Edition Entities.
For more information about using the geoadm start command , see Enabling the Geographic Edition Software.
Note - If you are using the Availability Suite feature of Oracle Solaris for data replication, a logical hostname is created for each device group to be replicated. For more information, see Chapter 1, Replicating Data With theAvailability Suite Feature of Oracle Solaris, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite.
The following table lists the Oracle Solaris Cluster and Geographic Edition components that require IP addresses. Add these IP addresses to the following locations:
All naming services that are being used
The local /etc/inet/hosts file on each cluster node, after you install the Oracle Solaris OS software
Table 2-1 IP Addresses Required by Geographic Edition Software
For more information about configuring the IP address and host maps during the installation of Oracle Solaris Cluster software, refer to Chapter 2, Installing Software on Global-Cluster Nodes, in Oracle Solaris Cluster Software Installation Guide.
A device group is a hardware resource that is managed by the Oracle Solaris Cluster software. A device group is a type of global device that is used by the Oracle Solaris Cluster software to register device resources, such as disks. A device group can include the device resources of disks and Solaris Volume Manager disk sets.
For information about configuring device groups in Oracle Solaris Cluster software, refer to Chapter 5, Administering Global Devices, Disk-Path Monitoring, and Cluster File Systems, in Oracle Solaris Cluster System Administration Guide.
The Geographic Edition software configures Oracle Solaris Cluster device groups to include replication.
For more information about configuring data replication in Geographic Edition software, see Chapter 1, Replicating Data With theAvailability Suite Feature of Oracle Solaris, in Oracle Solaris Cluster Geographic Edition Data Replication Guide for Oracle Solaris Availability Suite.
