How to Configure a Disk 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:

  • Introduction to Data Replication

  • Guidelines for Configuring Data Replication

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

Steps

1. Access nodeA as superuser.

   nodeA is the first node of the primary cluster. For a reminder of which node is nodeA, see Figure 6–7.

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

   For information about configuring a disk group by using the VxVM software, see Chapter 4, SPARC: Installing and Configuring VERITAS Volume Manager.

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

   nodeA# /usr/cluster/bin/scconf -a \ -D type=vxvm,name=devicegroup,nodelist=nodeA:nodeB

   The disk device group is called devicegroup.

4. Create the file system for the disk device group.

   nodeA# /usr/sbin/newfs /dev/vx/rdsk/devicegroup/vol01 < /dev/null nodeA# /usr/sbin/newfs /dev/vx/rdsk/devicegroup/vol02 < /dev/null

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