vxdiskadd - add one or more disks for use with Veritas Volume Manager
The vxdiskadd utility configures disks for use by
Veritas Volume Manager (VxVM).
Disks must already have been formatted, and have a valid, recognized partition
table. Currently, DOS and SOLARIS partitioning is supported.
vxdiskadd prompts the user for
a disk group name and disk name for the disks. If no disk group name
specified, the disks will be left as unassigned
replacement disks for future use. A new disk group may be created that
will become the disks disk group.
If a disk group is specified for the disks,
the user is prompted for whether the disks should be designated as spares
for the disk group.
If a disk is found to already contain partitioning not set up by VxVM,
the user will be asked whether the disk should be encapsulated.
Encapsulation will turn each partition of the disk
into a volume. A disk should be encapsulated if it contains file systems
or data that should not be overwritten. If encapsulation is not desired
for a disk, the disk can be initialized as a new disk for use by VxVM.
For new disks, all space on the disk becomes free space
in the disks disk group. vxdiskadd interactively allows
initialization to be done for all the disks specified or
allows the user to ask to make the decision for each disk individually.
One or more disks may be specified with a

All courses of action that do not involve clear failure conditions require
prompts from the user, with defaults supplied as appropriate. Help is made
available at every prompt. Entering ? in response to a prompt displays
a context-sensitive help message.

This reattach action is performed by calling the
Encapsulation of disks that have existing contents
This is the
default action for disks that do not have a valid, existing
Veritas Volume Manager private region, but that do have a VTOC or EFI label.
Encapsulation is performed by calling vxencap.
Initialization of a disk with reserved regions and partitions
Initialization of the disk is
performed by calling vxdisksetup.
Adding a disk to an existing disk group
This operation can be performed independently of the initialization of the
disk drive. The operation adds the disk to the group so that its
storage is added to the free space pool in that disk group.
utility can subsequently allocate from that free space.
Creation of new disk groups in which to import a new disk
If disks are added that are required to be put into a disk
group that does not exist,
the option of creating the disk group is offered.
Some environments provide guidelines to optimize VxVMs interaction
with intelligent storage systems. If these guidelines are present, VxVM
follows the guidelines when adding disks to disk groups. If the
operation fails due to these guideline(s), you are prompted to use the
force option. The force option ignores any such storage-specific

EFI disks cannot be added to a disk group that is compatible with
the Cross-platform Data Sharing (CDS) feature, nor can they be formatted
as CDS disks.
