Creating the Storage Infrastructure with Veritas
Cluster Volume Manager (CVM)
NOTE Check the Serviceguard, SGeRAC, and SMS Compatibility and Feature
Matrix and the latest Release Notes for your version of Serviceguard for
up-to-date information on support for CVM (and CFS - Cluster File
System): http://www.docs.hp.com -> High Availability - >
Serviceguard.
This section has information about configuring the Veritas Cluster
Volume Manager without Veritas CFS (Cluster File System). The
configuration may be needed to set up raw devices for Serviceguard
Extension for RAC.
The previous section (“Creating a Storage Infrastructure with Veritas
Cluster File System (CFS)” on page 251) has information about
configuring a cluster with CFS.
Both solutions - with and without CFS - use many of the same
commands, but the processes are in a slightly different order.
Before starting, make sure the directory in which VxVM commands are
stored (/usr/lib/vxvm/bin) is in your path. Once you have created the
root disk group with vxinstall, you can use VxVM commands or the
Veritas Storage Administrator GUI, VEA, to carry out configuration
tasks. Instructions for running vxinstall are in the Veritas Installation
Guide for your version. For more information, refer to the Veritas Volume
Manager Administrator’s Guide for your version.
Separate procedures are given below for:
• Initializing the Volume Manager
• Preparing the Cluster for Use with CVM
• Creating Disk Groups for Shared Storage
