Managing Device Groups

A device group is a hardware resource that is managed by the Sun Cluster software. A device group is a type of global device that is used by the Sun Cluster software to register device resources, such as disks. A device group can include the device resources of disks, Solaris Volume Manager disksets, and VERITAS Volume Manager disk groups.

For information about configuring device groups in Sun Cluster software, refer to Chapter 4, Administering Global Devices, Disk-Path Monitoring, and Cluster File Systems, in Sun Cluster System Administration Guide for Solaris OS.

The Sun Cluster Geographic Edition software configures Sun Cluster device groups to include replication.

For more information about configuring data replication in Sun Cluster Geographic Edition software, see Chapter 1, Replicating Data With Sun StorEdge Availability Suite 3.2.1 Software, in Sun Cluster Geographic Edition Data Replication Guide for Sun StorEdge Availability Suite, Chapter 1, Replicating Data With Hitachi TrueCopy Software, in Sun Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy, and Chapter 1, Replicating Data With EMC Symmetrix Remote Data Facility Software, in Sun Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility.
