How to Configure a Device Group on the Primary Cluster

Before You Begin

Ensure that you have completed the following tasks:

• Read the guidelines and requirements in the following sections:

  • Understanding Sun StorageTek Availability Suite Software in a Cluster

  • Guidelines for Configuring Host-Based Data Replication Between Clusters

• Set up the primary and secondary clusters as described in Connecting and Installing the Clusters.

1. Access nodeA as superuser or assume a role that provides solaris.cluster.modify RBAC authorization.

   The node nodeA is the first node of the primary cluster. For a reminder of which node is nodeA, see Figure 4–9.

2. Create a disk group on nodeA that contains volume 1, vol01 through volume 4, vol04.

   For information about configuring a disk group by using the VxVM software, see the Chapter 5, Installing and Configuring VERITAS Volume Manager, in Sun Cluster Software Installation Guide for Solaris OS.

3. Configure the disk group to create a device group.

   nodeA# cldevicegroup create -t vxvm -n nodeA nodeB devgrp

   The device group is called devgrp.

4. Create the file system for the device group.

   nodeA# newfs /dev/vx/rdsk/devgrp/vol01 < /dev/null nodeA# newfs /dev/vx/rdsk/devgrp/vol02 < /dev/null

   No file system is needed for vol03 or vol04, which are instead used as raw volumes.
