Creating the Storage Infrastructure with Veritas Cluster Volume Manager (CVM)
NOTE: Check the Serviceguard/SGeRAC/SMS/Serviceguard Manager Plug-in 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, the Cluster File System): http://www.hp.com/go/
hpux-serviceguard-docs.
This section explains how to configure the Veritas Cluster Volume Manager without Veritas CFS
(Cluster File System) — for example, to set up raw devices for Serviceguard Extension for RAC.
You can use the instructions below to configure CVM disk groups for raw access whether you have
purchased CVM as a standalone product, or as part of a bundle that includes CFS.
NOTE: You must use CFS if you want to configure file systems on your CVM disk groups; see
“Creating a Storage Infrastructure with Veritas Cluster File System (CFS)” (page 204).
The two sets of procedures — with and without CFS — use many of the same commands, but in
a slightly different order.
Before you start, 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.
You need to do the tasks described in the following sections:
• “Initializing the Veritas Volume Manager ” (page 225)
• “Preparing the Cluster for Use with CVM ” (page 225)
• “Identifying the Master Node” (page 225)
• “Initializing Disks for CVM” (page 225)
• “Creating Disk Groups” (page 226)
• “Creating Volumes ” (page 226)
• “Adding Disk Groups to the Package Configuration ” (page 226)
For more information, including details about configuration of plexes (mirrors), multipathing, and
RAID, refer to the HP-UX documentation for the Veritas Volume Manager. See the documents for
HP Serviceguard Storage Management Suite posted at http://www.hp.com/go/
hpux-serviceguard-docs.
