Setting Up VxFS 5.0 and VxVM 5.0
Chapter 5 37
• Specify the name of the default disk group to be used by the commands if the -g option is
not used to specify a disk group.
• Choose whether to use enclosure-based naming for disks. This type of naming enables you
to associate more meaningful disk-access names with disks in different arrays.
NOTE For more information on setting up VxVM disk groups and volumes after
installation, refer to section “Configuring Veritas Volume Manager” in the
Veritas Volume Manager 5.0 Administrator’s Guide.
To configure VxVM 5.0, complete the following steps:
Step 1. To set up the Veritas Volume Manager, enter the following:
# vxinstall
The following output is displayed:

a VxVM license key on your system, you will need to do so if you want to
use the full functionality of the product.
Licensing information:
System host ID: <hostid>
Host type: <servertype>
Are you prepared to enter a license key [y,n,q] (default: n) y
Step 2. To use enclosure-based names, enter y when prompted by the vxinstall utility:
Do you want to use enclosure based names for all disks ? y
[y,n,q,?] (default: n)
NOTE Disks use the traditional naming format, usually c#t#d#.
Enclosure-based naming allows disk devices to be named for
enclosures rather than for the controllers through which they are
accessed. In a Storage Area Network (SAN) that uses Fibre Channel
hubs or fabric switches, information about the disk location provided
by the operating system may not correctly indicate the physical
location of the disks. Enclosure-based naming allows VxVM to access
