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 199).

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 220)

“Preparing the Cluster for Use with CVM ” (page 220)

“Identifying the Master Node” (page 220)

“Initializing Disks for CVM” (page 220)

“Creating Disk Groups” (page 221)

“Creating Volumes ” (page 221)

“Adding Disk Groups to the Package Configuration ” (page 221)

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.
