NOTE: All nodes in the cluster must be either SGeRAC nodes or Serviceguard nodes. For the
up-to-date version compatibility for Serviceguard and HP-UX, see the SGeRAC release notes for
your version.

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 18).
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.
Cluster information is provided via a special system multi-node package, which runs on all nodes
in the cluster. The cluster must be up and must be running this package before you can configure
VxVM disk groups for use with CVM. Disk groups must be created from the CVM Master node.
The package for CVM version 5.x and later is named SG-CFS-pkg. CVM allows you to activate
storage on one node at a time, or you can perform write activation on one node and read activation
on another node at the same time (for example, allowing backups). CVM provides full mirroring
and dynamic multipathing (DMP) for clusters. CVM supports concurrent storage read/write
access between multiple nodes by applications that can manage read/write access contention,
such as Oracle Real Application Cluster (RAC).
NOTE: CVM (and CFS – Cluster File System) are supported on some, but not all current releases
of HP-UX. See the latest release notes for your version of Serviceguard at
www.hp.com/go/hpux-serviceguard-docs.
Veritas Storage Management Products
Veritas Volume Manager (VxVM) 3.5 is not supported on HP-UX 11i v3. If you are running
VxVM 3.5 as part of HP-UX (VxVM-Base), version 3.5 will be upgraded to version 4.1 when you
upgrade to HP-UX 11i v3.
About Multipathing
Multipathing is automatically configured in HP-UX 11i v3 (this is often called native
multipathing), or in some cases can be configured with third-party software such as EMC
Powerpath.
