Installing Serviceguard Extension for RAC
Installing Serviceguard Extension for RAC includes updating the software and
rebuilding the kernel to support high availability cluster operation for Oracle Real
Application Clusters.
Prior to installing Serviceguard Extension for RAC, the following must be installed:
• Correct version of HP-UX
• Correct version of Serviceguard
NOTE: For the most up-to-date compatibility information for Serviceguard and
HP-UX, see the Serviceguard Extension for RAC support matrix located at
http://docs.hp.com -> High Availability -> Serviceguard Extension for Real
Application Clusters-> Support Matrixes.
To install Serviceguard Extension for RAC, use the following steps for each node:
1. Mount the distribution media in the tape drive, CD, or DVD reader.

5. After choosing the bundle, select OK. The software is loaded.
Veritas Cluster Volume Manager (CVM) and Cluster File System (CFS)
You may choose to configure cluster storage with the Veritas Cluster Volume Manager
(CVM) instead of the Volume Manager (VxVM). The Base-VxVM provides some basic
cluster features when Serviceguard is installed, but there is no support for software
mirroring, dynamic multipathing (for active/active storage devices), or numerous other
features that require the additional licenses (on HP-UX releases that support Veritas
CFS and CVM; see “About Veritas CFS and CVM from Symantec” (page 25)).
VxVM supports up to 16 nodes, and CVM supports up to 8. CFS 5.0 also supports up
to 8 nodes; earlier versions of CFS support up to 4. The VxVM Full Product and CVM
are enhanced versions of the VxVM volume manager specifically designed for cluster
use. When installed with the Veritas Volume Manager, the CVM add-on product
provides most of the enhanced VxVM features in a clustered environment. CVM is
truly cluster-aware, obtaining information about cluster membership from Serviceguard
directly.
