To display or change the default values for initializing disks, select menu item
21 (Change/display the default disk layout) from the vxdiskadm

Adding a disk to VxVM
Formatted disks being placed under VxVM control may be new or previously
used outside VxVM. The set of disks can consist of all disks on the system, all
disks on a controller, selected disks, or a combination of these.
Depending on the circumstances, all of the disks may not be processed in the
same way.
Caution: Initialization does not preserve data on disks.
When initializing multiple disks at one time, it is possible to exclude certain
disks or certain controllers. To exclude disks, list the names of the disks to be
excluded in the file /etc/vx/disks.exclude before the initialization. You
can exclude all disks on specific controllers from initialization by listing those
controllers in the file /etc/vx/cntrls.exclude.

as spares. Or they may be added as nohotuses to be excluded
from hot-relocation use. The selected disks may also be
initialized without adding them to a disk group leaving the
