voldiskadd - Adds one or more disks for use with the Logical Storage
The voldiskadd interactive utility sets up new disks that are added to the
system after the initial system installation and configures the disks for
use by the Logical Storage Manager. A valid disk label must exist on the
disk before using the voldiskadd utility.
One or more disks may be specified using a disk-address-list. Disk
addresses in the list have the form dskn (for the entire disk) or dsknp
(for a specific partition). When specifying multiple disks, use a space
between entries. Disk address names relate directly to device names in the
For example, the following are valid voldiskadd disk-address-list specifi-
# voldiskadd dsk1
# voldiskadd dsk2 dsk3a
The file /etc/vol/disks.exclude may be used to exclude disks from use by
voldiskadd. Each line of the file specifies the name of a disk to exclude
(for example, dsk5).
The voldiskadd utility prompts you for a disk group name and disk media
name for the disks. If you specify a new disk group name, that disk group
is created for the new disks. If you do not specify a disk group name, the
disks are left as unassigned replacement disks for future use. If you
specify an existing disk group name, you are prompted for whether the disks
should be designated as spares for the disk group.
If a disk is found to already contain non-Logical Storage Manager parti-
tioning, you are asked whether the disk should be encapsulated. Encapsula-
tion turns each partition of the disk into a volume. Encapsulate a disk if
it contains file systems or data that should not be overwritten. If you do
not want to encapsulate the disk, you can initialize it as a new disk for
use by the Logical Storage Manager. For new disks, all space on the disk
becomes free space in the disk's disk group.

The voldiskadd utility supports the following general classes of actions:
+ Initializing a disk with reserved regions and partitions.
Disk initialization is performed by calling voldisksetup command.
+ Adding a disk to an existing disk group.
You can add disks to disk groups independently of initializing disks,
to add a disk's storage space to a disk group's free space pool. The
volassist command may subsequently allocate from that free space. You
can also add the disk as a hot spare device.
+ Creating new disk groups in which to add new disks.
If no disk group exists for adding disks, you can create a new disk
+ Encapsulating disks that have existing contents.
This is the default action for disks that do not have a valid, exist-
ing Logical Storage Manager private region, but that do have a disk
label. Encapsulation is performed by calling volencap.
+ Reconnecting a drive that was temporarily inaccessible.
This situation is detected automatically, by noting that the specified
drive has a disk ID that matches a disk media record with no currently
associated physical disk. After reconnection, any stale plexes refer-
ring the disk are reattached, and any stopped volumes referring the
disk are restarted. This reattach action is performed by calling the

If you are sure that the disk partition does not have valid data and that
the partition can be added to LSM, you can ignore the warning message by
entering y at the prompt. The voldiskadd command will proceed to initialize
the disk partition and add it to LSM.
