HACMP does not deal with disks (disk devices), it only deals with volume groups. Basically, a "resource group" in HACMP is:
- a bundle of filesystems, organized in certain volume groups
- a number of processes to be started/stopped
- an (several) IP addresses to serve up data/services
When a resource group starts: the VGs are activated (varyonvg), the respective filesystems are mounted, the processes are started (via start-scripts) and the IP-address is activated on some interface.
When the resource group stops this process is reversed: the IP address is deleted from the interface, the processes are stopped (via stop-scripts) and the filesystems are unmounted, then the VGs are deactivated.
How and from what devices these VGs are built is transparent for HACMP. The only requirement is that HACMP is able to activate the VGs from every cluster node.
I hope this helps.

NAME
vxinstall - menu-driven Veritas Volume Manager initial configuration procedure
SYNOPSIS
vxinstall
DESCRIPTION
The vxinstall utility provides a menu driven interface to configure Veritas Volume Manager (VxVM). If you install the Veritas Volume Man-
ager software package using the operating system's package administration commands, you can run vxinstall to configure VxVM for initial use
on your system.
Note: If you use the Veritas software installation scripts, do not run this utility.
OPERATIONS
Licensing
vxinstall first asks if you want to view the Veritas licenses already installed on the system. Answering "yes" is equivalent to exe-
cuting the vxlicrep command (see vxlicrep(1)).
You are then asked if you want to add licenses for other Veritas products. Answering "yes" is equivalent to running the vxlicinst
command (see vxlicinst(1)). and entering a license key.
Enclosure-Based Naming
You can choose whether you want to use disk access names that are based on the device names assigned by the operating system, or that
are based on names that you assign to enclosures.
System-Wide Default Disk Group
You can enter the name for the default disk group (defaultdg). This is an alias for the disk group name that should be assumed if the
-g option is not specified to a command, or if the VXVM_DEFAULTDG environment variable is undefined. By default, defaultdg is set to
nodg (that is, no disk group).
NOTES
From release 4.0 of VxVM, it is no longer necessary to run vxinstall to configure the rootdg disk group. Disks and disk groups may be
added to VxVM by running commands such as vxdiskadm(1M) or by using the graphical user interface without first running vxinstall. The
operation of VxVM does not require any disk groups to have been configured, and a disk group named rootdg does not need to be present on
the system. Any disk group may be configured as the default disk group that is to be used with VxVM commands. Any disk group named rootdg
has no special significance to VxVM. See the vxdg(1M) manual page for further details.
