This section provides the following guidelines for planning volume management of your cluster configuration:
Oracle Solaris Cluster software uses volume manager software to group disks into device groups that can then be administered as one unit. You must install Solaris Volume Manager software on all nodes of the cluster.
See your volume manager documentation and Configuring Solaris Volume Manager Software for instructions about how to install and configure the volume manager software. For more information about the use of volume management in a cluster configuration, see Multihost Devices in Oracle Solaris Cluster Concepts Guide and Device Groups in Oracle Solaris Cluster Concepts Guide .
