Complete the procedure How to Configure a Device Group on the Primary Cluster.
Access nodeC as superuser or assume a role that provides solaris.cluster.modify RBAC authorization.
Create a disk group on nodeC that contains four volumes: volume 1, vol01, through volume 4, vol04.
Configure the disk group to create a device group.
nodeC# cldevicegroup create -t vxvm -n nodeC devgrp
The device group is named devgrp.
Create the file system for the device group.
nodeC# newfs /dev/vx/rdsk/devgrp/vol01 < /dev/null nodeC# newfs /dev/vx/rdsk/devgrp/vol02 < /dev/null
No file system is needed for vol03 or vol04, which are instead used as raw volumes.
